Is it Safe? The Ventura County Callbox Accessibility Program

Introduction

In California over the last half-dozen years, the roadside callbox
has become a significant component of the highway network in major
metropolitan areas. There are today over 14,000 callboxes across the
state providing motorist assistance to the millions of California
residents and visitors travelling within the state. Each day, over
100,000 motorists use the callboxes to obtain roadside services, such
as towing, and to report accidents or unsafe conditions.

This callbox "boom" began with the passage of state legislation in
1986 which  authorized counties to levy a $1 fee on vehicles
registered within their borders to support the installation,
operation and maintenance of a roadside callbox system. Since that
time, the number of callboxes in operation throughout the state has
climbed steadily. However recent federal actions may "stem the tide"
and significantly reduce the number of new callbox installations in
California. Specifically, recently promulgated rules under the
Americans with Disabilities Act Architectural Guidelines (ADAAG)
require full physical site access at all new callboxes.

While California's callbox agencies have supported site access within
the confines of state highway design standards, encouraging or
requiring mobility-impaired drivers to get out of their cars to use
a callbox was not considered a good solution to the problem. In fact,
a number of mobility impaired Ventura County residents pointed out
that when their car was on the side of the highway, they simply were
unable to get out of their car. Recognizing these problems, The
Ventura County Service Authority for Freeway Emergencies (SAFE) set
about trying to understand the basic issue and then develop a program
which meaningfully improved callbox accessibility in a manner
acceptable to the community.

This paper discusses the Ventura County program and the "regulatory"
environment in which it has been implemented. More specifically, the
paper contains: 1) A brief overview of the recently issued callbox
accessibility requirements; 2) a discussion of California's viewpoint
and difficulties with these rules; and 3) Ventura County's program
for improving accessibility to the callbox system and its services.

While Ventura County, with its 700,000 residents and 550,000
registered vehicles, represents less than three percent of the
state's people and cars, it has been "aggressive" in the area  of
callbox accessibility. For this reason, the programs described here
may be the forerunners of future statewide efforts.

Callbox Accessibility Requirements

California's many SAFE programs have been grappling with the issue of
callbox accessiblity repeatedly since the mid-1980's. In 1988, the
Office of the State Architect declared that there iwere no State
regulations governing access to callbox systems by disabled persons,
with the exception of the height of the callbox unit and the length
of the handset cord. Also, state callbox design standards require a
level surface and installation of a concrete pad of a size sufficient
to safely accomodate a wheelchair.


Although it may seem narrow-minded or parochial, the SAFE's had in
essence focused only on making their callbox sites accessible. It was
universally accepted in California that the SAFE's did not have the
responsiblity, authority, or financial wherewithal to address
accessibility along the highway system. This viewpoint has, however,
been under challenge since the passage of Title II of the Americans
with Disabilities Act (ADA) of 1990.

ADA extended protection of the civil rights of disabled persons to
include state and local government agencies, and requires that
existing programs and services be readily accessible and usable by
individuals with disabilities. The ADA did not specifically address
callbox accessibility and for the next two years a rather unfocused
debate took place among the  SAFE's, the State Department of
Transportation (Catrans) and advocates for the rights of disabled
individuals. Then, in December, 1992, the Architectural and
Transportation Barriers Compliance Board (Access Board) released a
Notice of Proposed Rulemaking (NPRM) that for the first time
specifically addressed access to roadside callbox systems by
physically challenged drivers.

The 1992 NPRM identified the following specific requirements for
callbox accessiblity:

     .     Controls and operating mechanisms shall be operable with
           one hand and shall not require tight grasping, pinching or
           twisting of the wrist;

     .     The highest operable part of the callbox shall not exceed
           54 inches above the finished grade;

     .     The force required to operate the callbox shall not exceed
           5 pounds of force;

     .     Both visual and auditory acknowledgment of call receipt
           (answering of the call) are required,while voice
           communications is not;

     .     A firm, stable, slip-resistant surface area not less than
           30"x48" shall be provided; and

     .     The level callbox site is prohibited from being separated
           from the roadway by a ditch, gutter, curb or other barrier
           (including dirt, rocks, etc.).

In the summer of 1994, the Access Board issued its Interim Final Rule
(IFR) which contained the above elements with the lone substantive
change of establishing a "highest operable part" maximum height of
48".


The California Response
While the issuance of the NPRM in late 1992 was intended to "provide
guidance to the Department of Justice in establishing new standards,"
it also accomplished a second


 objective: it united California's disparate callbox agencies on the
issue. This second accomplishment is not to be taken lightly. For
several years the state's callbox agencies had discussed and debated
callbox accessiblity and had failed to reach agreement on a state-
wide approach. This disagreement existed not only among the SAFE's
but also with Caltrans, the agency responsible for the state highway
system, and the California Highway Patrol (CHP), the agency
responsible for answering and often responding to callbox calls.

This new unity in California callbox circles was based almost
entirely upon one specific requirement in the NPRM: the requirement
of an "unobstructed" pathway between the roadway shoulder and the
callbox site. The California callbox and site design standard was
developed with accessibility in mind and it substantially met most
all of the other requirements. (The decision to change the operable
height requirement to 48" in the IFR may create problems for the
callboxes, which are set at the standard 54". If the 48" requirements
is maintained, a redesign of the California callbox system may be
required.)

California's opposition to the requirement for a continuous pathway
from shoulder to the callbox site was based upon  concerns related to
basic safety and functionality as well as highway design
considerations particular to California. The basib concerns could be
summarized as follows:

     .     Standard freeway and conventional highway shoulders do not
           meet ADA Accessiblity Guidelines regarding slopes, ramps or
           passenger loading zones;

     .     Freeway shoulder standards include berms and curbs for
           drainage and erosion control;

     .     The SAFE's have no authority over the design and
           construction of roadway shoulders, nor do they have the
           financial capability to construct or maintain modified
           shoulders; and

     .     There is along most highway a level of roadway debris
           (rocks, dirt, glass, etc.) which makes wheelchair operation
           particularly challenging if not impossible.

These concerns are directed toward the roadway environment and not
the callbox sites themselves. They are based on the fundamental
notion that a freeway or highway shoulder is not a safe place to be,
and it is an even less safe environment for a mobility-impaired
individual. Interestingly, accessiblity "advocates" rarely argue that
this is an untrue assessment. What they argue is that this fact is
irrelevant.

For most of the SAFEs in the state, as well as Caltrans and the CHP,
these concerns were based on engineering practices, observations of
pedestrian activities on highways, and the financial realities
associated with highway construction. Caltrans' standards call for an
eight-foot shoulder on most state highways. This does not provide
sufficient width for a

wheelchair user to safelypark a van or automobile and get out of the
vehicle (tje standard width for safe operation of a wheelchair lift,
for exmple, is thirteen feet). The problem is compounded by the fact
that in many urban areas in the state, the standard eight-foot
shoulder has been narrowed to make room for more travel lanes on
congested freeways.

In addition, the standard cross-slope for highway shoulders is five
percent, which makes wheelchair maneuverability extremely difficul.
This problem is compounded by any significant running slope which may
be present. In Ventura County, for example, many lengthy sections of
highway have been constructed at grades of three to five percent,
with one of our busiest freeway sections at over eight percent. These
roadway sections simply cannot be made wheelchair accessible.

Finally, California's freeway design standards include berm and/or
curbs at the edge of pavement to control drainage and thereby prevent
erosion, which is viewed at best as a maintenance problem and at
worst as a safety hazard. The SAFE for the San Francisco Bay Area has
invested significant time and money in developing a solution to this
problem. To date, their design solutions have carried with them a
high price tag (in the neighborhood of $1000 per site) and a concern
that they may compromise roadway drainage or create a hazard. For
this second reason they have yet to receive Caltrans approval.

For the Ventura County SAFE, these concerns were reinforced by the
opinions of members of an Accessibility Committee which had been
formed in mid-1991. The committee, made up almost entirely of
mobility and speech and/or hearing-impaired county residents, had
been evaluating callbox accessibility for over a year when the NPRM
was relased. They had evaluated a number of possible methods for
improving access to callbox services. In addition to physical site
access, the committee evaluated the use of CB radios, distress flags,
cellular phones, telecommunication devices for the deaf (TDD), and
custom hand-held remote control units.

The preference was for a "solution" that met the needs of both
mobility and hearing/speech impaired drivers. However, it became
clear that the needs of each group were very different and that any
Accessibility Plan would involve two distinct programs. It is most
important to mention in the context of this paper, however, that the
primary desire of the two groups was the same. Namely, that neither
the mobility nor hearing/speech impaired committee members wanted to
be outside of their vehicles on the roadway shoulder.

This was particularly true for the members with mobility impairments.
While they encoraged, if not demanded, the construction of physical
site access improvements where feasible, they also without exception
stated that they would never leave the relative safety of their
vehicle to  get to a callbox, even if it was accessible. This
viewpoint was shared by a number of individuals and groups in the
state and many of them testified accordingly at the regional hearing
held to solicit comments on the NPRM. Most importantly for Ventura
County, this was the viewpoint expressed at our SAFE hearings, and it
formed the basis of our Accessibility Plan.


Prior to discussing in detail the Ventura County SAFE's accessibility
programs, it is important to note that California's current standard
callbox also does not meet the new requirement for a visual as well
as auditory call acknowledgement. California's callboxes are
essentially telephones which provide full voice communication between
the user and the CHP. They do not provide any visual indicators.
Unlike the pathway requirement, however, there was general agreement
among the SAFEs that this requirement was reasonable attainable. This
viewpoint was based on the anticipated "affordability" of the
improvement and the fact that it was contained  within the callbox
itself and not a part of the roadway environment. In fact, callboxes
currently being installed in the Sacramento metropolitan area are
equipped with a call indicator light. Ventura County's proposed TDD
callbox program, and a remote control device being developed in the
San Francisco Bay Area, would also meet this requirement.


Ventura County's Program

As mentioned above, the SAFE's Accessibility Committee wrestled for
almost a year with the development of a program to improve callbox
accessibility. Ultimately, the recommendation of the committee, which
was adopted by the SAFE Board, was to implement a program with two
primary components: the distribution of portable cellular telephones
and the develoment of a TDD callbox. The former program was
implemented in mid-1993 and is on-going while the latter is currently
in the field test phase. Each is dicussed in detail below.



Portable Phone Program

This program, formerly referred to as our "Cellular Telephone Program
for the Mobility Impaired," can be described very simply as the
distribution of portable cellular telephones to Ventura County
drivers who cannot use a roadside callbox due to a mobility
impairment. While this described the program well, it also raised a
number of questions for the potential user: Where do I get the phone?
How much does it cost? Can I use the phone for personal calls? What
qualifies as a mobility impairment? All of these questions had to be
answered before the program could be initiated. And the SAFE relied 
on our Accessibility Committee to help provide the answers.

First, in keeping with the goal of "equivalent access," it was
decided the phones would be provided at no cost to the user. After
all, there is no charge to the motorist to use the roadside callbox.
In addition, there is no deposit required. This decision was based
not only on the desire for equivalent access, but also on the fact it
was anticipated that many of those in the program would be on a fixed
incomme, and any deposit, no matter how small, could pose a hardship.
Selection of the type of phone to be distributed was also an issue to
be addressed. The decision was made to use an off-the-shelf portable
telephone. This was based on the desire to implement the program as
quickly as possible with equipment which has proven its worhtiness
and durability. A request for proposal (RFP) was prepared and bids
solicited from phone manufacturers and distributions.

The Ventura County Accessibility Committee was involved in developing
the RFP and phone specifications, focusing primarily on size, weight,
power source and ease of use. Three different phone models were
tested over a period of several days by each of the committee members
so that they could make an imformed recommendation as possible. The
recommended unit, manufactured by Motorola, has been purchased over
the past year at a cost ranging from $200 to $300 dollars.

In California today, all 911 calls made from cellular phones are
answered by CHP dispatchers. These same dispatchers are responsible
for answering callbox calls. Using the equivalent access principle as
a guide, it was decided that the phones distributed through this
program would be limited to making 911 calls only. However, the
option to subscribe for additional service, fully at the users
expense, through the cellular service provider was left open. This
was done for two reasons: 1) it did not seem logical to prevent 
additional services if there was no cost to the SAFE; and 2) it held
out to the cellular service provider the potential for additional
customers.

Mention of the potential market for the service provider raises a
very important point: This program could not have been put in place
without the assistance and cooperation of Cellular One, our cellular
service provider. To their credit, Cellular One recognized the value
of the program to the community and public service "mileage" that it
could gain them. As a result, they agreed to provide access to 911
calls at no cost. In addition, they have contributed to the cost of
printing program information brochures which have been distributed
across the county. Cellular One's cooperation has led to a program
which, on the operational side, has been relatively simple and
inexpensive to operate.

Given the limited budget of the SAFE, the Accessibility Committee
recommended the program be administered on a "first-come-first-
served" basis. (Note: To date all eligible applicants have received
a cellular phone.) Along these lines, the committee also recommended
structuring the program so that those most in need of the service
were eligible to participate. Based on this direction, and on the
desire to keep the eligiblity requirements as simple as possible, the
following eligibility criteria were adopted:

The applicant must:

     .     Have a disability which prohibits them from reaching a
           roadside callbox. 

     .     Be an independent driver.

     .     Be a permanent resident of Ventura County or be visiting
           for at least six months.


The SAFE relies on a combination of in-person interviews, referrals
and recommendations from medical care providers and other health care
and social service agencies in determining whether an applicant meets
the first criteria. Specifically, after completing an application,
which includes a referral section, an application is required to
attend an in-person interview.

The interview allows the certification coordinator to make an initial
informal dtermination of the applicant's functional ability to use a
roadside callbox. If the coordinator is unable to make a
determination at that time, a verification form requesting additional
information is sent to the reference listed in the application. An
appeals process has also been developed but has as yet not been used.

The second criteria is intended to make ineligible those persons who
are mobility impaired but do not drive (i.e. those who travel at all
times with a driver/attendant). In the event roadside asssistance is
required for these individuals, the driver/attendant can access the
system via the roadside callbox. Interestingly, this criteria was
proposed and supported unanimously by the Accessibility Committee.
They recognized not only that funds were limited but also that those
funds were derived from a fee paid by drivers, and the callbox system
was put in place for the drivers benefit.

The third and final criteria is based upon the statutory restiction
that SAFE funds be spent only on callbox programs (and a small number
of other incident management activities) in the county within which
the funds are collected. In other words, Ventura County cannot fund
a callbox program in Los Angeles County, and vice-versa. In
recognition of the needs of "long-term" visitors to the county, the
Accessibility Committee recommended a six-month minimum stay for a
visitor to be eligible for the program. To date, no visitors have
applied for a cellular phone.

The Cellular Telephone Program has been in place for over one year
and has proven to be very successful. To date, we have distributed
almost 250 phones to Ventura County residents. The program has been
very well received, with extensive and positive local as well as
national (CNN) and international news coverage. Local client groups
and social service organizations have been provided marketing
materials and information brochures to make potential participants
aware of the program.

The program has also proven very easy to administer. The simple
eligibility criteria and application process are easily understood by
the applicants and as a result much easier to explain and carry out.
This is illustrated well by the fact that almost 10% of the
applicants have been denied telephones yet there has not been a
single appeal.

These outreach, application and administrative functions are carried
out by the county's ADA Coordinator, whose primary responsibility is
certifying persons for ADA transit services. As

expected, the telephone program tasks have meshed well with the ADA
Coordinator's primary responsibilities. The result is a program which
requires little administrative time other than the in-person
interview. To further economize on administrative time, eligibility
is typically determined at the in-person interview and equipment
training is provided at that time to approved applicants. To complete
the process, phone recipients are required to sign a simple
"contract" which outlines their responsibilities and the SAFE's
liability limitations.


TDD Callbox Program: 

As mentioned above, the Ventura County SAFE accessibility program was
guided in part by the objective of "equivalent access." The nature of
the highway environment (i.e. steep grades, cross-slopes, drainage
berms), unfortunately, made attainment of this objective very
difficult for mobility-impaired drivers. However, the situation for
hearing-impaired drivers was very different and "equivalent access,"
as a basic objective, seemed attainable.

Roadside callboxes in California today are basically telephones which
connect the user directly to the CHP. There are no lights, signals or
other message systems; in the parlance of the industry, they
represent "voice-only" communication. Moreover, this voice
communication is also "full duplex," meaning that it is person-to-
person with no limitations.

This level of communication has been the State standard largely at
the insistence of the CHP. The CHP does not wish to dispatch even one
of its limited number of field units to a scene unless it has a clear
and accurate understanding of the situation. Such an understanding
cannot be gained through a "Help" or "Fire" button or a series of
simple "yes" or "no" questions.

With this level of voice communication, "equivalent access" was
interpreted to mean an equal level of non-voice communication, which
to date has only been demonstrated through the use of a TDD. The
logical recommendation, from our Accessibility Committee's viewpoint,
was to install TDDs in the callboxes.
When this recommendation was approved by the SAFE Board in Mid-1992,
the SAFE began its pioneering effort to develop the first tdd
callbox. 

The challenges faced in the TDD Callbox Program were very different
than those in the Cellular Telephone program. The basic question was:
"Can we marry two existing technologies to create a new product that
is effective and affordable?" To answer this question, the SAFE
contracted with U.S. Commlink, an engineering/research & development
consultant working in the callbox field. To guide their effort, the
SAFE relied on the input and "expertise" of its Accessibility
Committee.

At the outset, a number of "design requirements" were established to
ensure a usable product was developed. Specifically, the TDD unit
needed to:

     .     Not interfere with, nor necessitate a redesign of , the
           current callbox electronics/software;

     .     Be weather-proof and substantially vandal-resistant;

     .     Be compatible with both of the current callbox designs;

     .     Not require any equipment or software change at the CHP
           dispatch center;

     .     Be readily usable and easily understood by regular TDD
           users;and

     .     Have reasonable installation and maintenance costs.

The Accessibility Committee's participation in the project was
directed toward making the unit usable and easily understood. While
this appeared at first glance to be a relatively simple task, the
comments and concerns of the committee members indicated otherwisa.
In the end,U.S. Commlink spent almost one year designing the keyboard
panel for the unit. Although during that time a number of committee
members complained the process was taking too long, the committee is
today unanimous in its support and enthusiasm for the product.

The requirements for compatibility with current callbox and CHP
electronics and software have also proven easy to attain. Our success
in these more technical areas was due largely to the cooperation of
the CHP and our callbox manufacturer, Cubic Communications, as well
as U.S. Commlink's experience with callbox operations. Related to
this, the operation of the TDD callbox is largely consistent with
current CHP dispatch procedures and protocol. This is essential if
CHP dispatch is to participate in the field test and if CHP
management is to support the program in general.

From a purely design perspective, the most daunting task was to
develop a product which was vandal-resistant. Callbox vandalism is
unfortunately a common occurrence in California. It ranges from
graffiti to theft to the occasional shotgun blast. While it is
impossible to design a TDD which can withstand all vandal "test," it
is important that it resist basic vandalism so that operations are
fairly continuous and maintenance costs are kept to a minimum. To
accomplish this task, very strong and durable materials have been
used and basic lab tests indicate they are reasonably effective.
Their effectiveness, however, will not be known until the current
field test and additional lab tests have been completed.

The final design-related requirement is on its face fairly simple:
The new TDD unit must fit into the existing callboxes. This
requirement is complicated though by the use of two distinct callbox
designs (and manufacturers) within the state. Both callbox types,
manufactured by Cubic Communications and GTE, function internally
much the same; they differ substantially in their housings. The Cubic
callbox is oval-shaped and constructed of cast aluminum, while the
GTE callbox is square and built of plastic. Until the issuance of
the IFR by the Access Board, this design requirement had been
addressed by U.S. Commlink. However, the IFR requirement for a 48"
inch maximum height for operable parts may make it impossible to fit
the TDD unit in the GTE callbox type. While we hope to overcome this
hurdle, the lack of a statewide application of the product may doom
its installation. Which leads to the final design restriction: Cost.

As might be expected, it is not likely to be inexpensive to purchase
and install a weather-proof, vandal-resistant and operating TDD in a
roadside callbox. Also not surprisingly, the cost is directly related
to the number of units to be purchased. Ballpark estimates by the
design consultants, while still preliminary, indicate that if Ventura 
County were to "go it alone," its 500 callbox TDDs would cost roughly
$1000 per unit to install. However, if all or a significant number of
the other SAFEsjoined in the project, that cost could be cut in half.
Obviously, the acceptance of the product by the "market" will have a
signicant impact on its future.

The size, if not the existence, of that market has also been effected
by the IFR and its requirement for visual as well as auditory call
acknowledgement. This has been interpreted in California to mean
installation of a simple signal light in the callbox is adequate to
meet ADA requirements and, more importantly, meet the needs of
hearing-impaired drivers. While a signal light  is certainly an
improvement over the current equipment, it is also just as certainly
not "equivalent access" to the system. Fortunately, a majority of
SAFEs are postponing a decision until the TDD Callbox field test is
complete in early 1995. Hopefully, local pressures for action in
combination with the IFR guidance will not force these SAFEs to act
before that time.


Conclusion 

The issue of access to the roadway callbox system in California is
not prone to an easy solution. In fact, it is clear there is no
single answer, and access will be improved through a combination of
different programs. In Ventura County, these programs include the
distribution of portable cellular telephones to our mobility-impaired
drivers, construction of physical site improvements where feasible,
and the development of a TDD callbox. While only the former two
programs have actually been implemented, we are hopeful in Ventura
County that the third element of the program will survive its field
test and be embraced by the callbox  "marketplace." California's
roadside callbox program has long served as a "model" for other
states and regions pursuing roadside assistance programs. The TDD
callbox will only continue that tradition.
