STREETS AND HIGHWAYS COMPONENT


OVERVIEW / BACKGROUND

Streets and highways are the backbone of the region's
transportation system and will continue to be into the foreseeable
future. The Regional Council estimates that in 1990, about 93
percent of all trips, on an average weekday, are made by private
vehicle; 72 percent as drivers, and 21 percent as passengers. In
1990, the Bureau of the Census documented that almost 80 percent of
the region's trips from home to work were in a private auto. The
Regional Council estimates that 73 percent of all trips were in
single-occupant vehicles (SOV), 17 percent in 2-person carpools,
and 2 percent in 3-person carpool.

Accommodating these auto trips is a roadway network totalling
16,700 miles in the four-county region. About 7 percent of this
mileage is under the state's jurisdiction, 76 percent under local
jurisdictions, and 17 percent under the jurisdiction of parks,
reservations, or other public lands.

Expenditures on transportation facilities have declined
dramatically relative to growth in vehicle miles of travel (VMT). 
The central Puget Sound region experienced the national "freeway
revolt" during the past 25 years as did many metropolitan regions. 
The long-term trend of resisting the placement of new highways
through built-up areas has firmly and clearly established a public
policy in this region that is unambiguous: major new or expanded
thoroughfares through developed urban and suburban areas are not
supported. Recent efforts to reintroduce new road alignments have
met with strong opposition and eventual abandonment of proposals. 
Options for new or substantially widened highway alignments through
residential areas, even if they were affordable, are limited by
public sentiment and policy.

Historical Perspective and Future Trends

The present transportation system was not designed for the current
levels of urbanization that continued growth has caused. The
freeway system designs of the 1950s and '60s were planned to
accommodate slower rates of growth. Moreover, due to fiscal,
environmental, and energy conservation concerns in the 1970s,
transportation plans were revised to reflect a regionwide policy of
fewer freeways in favor of higher capacity forms of transportation. 
In the process, 125 miles of proposed freeways or limited access
roadways were dropped from the plans.

Continued growth in the region is expected to result in a year 2020
population of more than 4 million with more than 2.4 million
employed. If existing travel behavior and conditions were to
persist, estimates show that this is likely to cause a doubling of
daily VMT in the region by year 2020.

Consequently, congestion over the next 25 years is expected to
worsen considerably demonstrated by several performance indicators. 
Trends reflecting low auto-occupancy rates, tolerable gas prices,
increases in per capita income, inexpensive and available parking,
more women entering the workplace, more registered vehicles, and
new housing and employment located in suburban areas, are an
indication that the propensity to travel by automobile will

Continue. Without implementation of aggressive demand management
and system management policies, this anticipated congestion may
have severe impacts on air quality, and economic growth. The focus
on accommodating travel increases has already shifted to transit,
ridesharing, and other public policies emphasizing alternatives to
private auto use.

VISION 2020 POLICY DIRECTION

VISION 2020 clearly establishes a transportation policy objective
of reducing dependence on the single-occupant vehicle, and
encouraging alternative modes of travel. VISION 2020 recognizes
that use of the auto as a relatively low-priced means of travel
does not support more geographically compact and transit-oriented
development patterns. Limited public works funding and local
resistance to new or wider freeways are forcing new ways of looking
at travel. The region is committed to reducing dependence on the
automobile, improving air quality, saving energy, preserving land
as open space, and making neighborhoods more livable.

However, VISION 2020 also recognizes that some highway improvements
and capacity enhancements are needed and has therefore embraced the
following policies:

-    Recognition of the mobility and accessibility needs of people,
     freight and goods;
-    Recognition of the specific mobility needs of business and
     industry;
-    Completion of key network linkages to provide continuity in
     circulation on the region's highway system;
-    Support for centers and provision of access to non-center job
     and residential areas within designated urban growth areas and
     rural center.

VISION 2020 further details the types of capacity improvements that
are consistent with the overall plan, and these are outlined in the
following table:

IMPLEMENTING VISION 2020

Identifying the Streets and Highways Facilities Component of the
Metropolitan Transportation System (MTS)

The Regional Council has several state and federal mandates to
identify regional facilities and services which comprise its
metropolitan transportation system. ISTEA requires the MPO to



MTP Baseline/Framework Report Background Information          Page 3





identify "an integrated metropolitan transportation system giving
emphasis to those facilities that serve important national and
regional transportation functions'. The Growth Management Act
(1990) and the Interlocal Agreement for Regional Planning (which
established the Regional Council) reinforce the need for identical
regionally significant facilities and services by the Regional
Transportation Planning Organization (RTPO).

As part of a cooperative effort by the Regional Council, WSDOT,
local jurisdiction, and other interested parties, an initial draft
of the highway component of the MTS is being developed. A consensus
has been developing over the past several months, and a core system
identified. Agreement on this core system has been relatively
straightforward due to recent completion of several federal and
state planning programs. The core system comprises all of the
region's designated National Highway System; all other state
highways; and other local principal arterials. Discussion is still
continuing to determine if any local system non-principal arterials
warrant consideration as having regional significance.

Conceptual Basis for Defining "Metropolitan" Facilities and
Services

MTS facilities are to be defined both functionally as well as
geographically. A facility should be part of the MTS if it provides
access to any activities crucial to the social or economic health
of the central Puget Sound region. Facilities that weave parts of
the region together by crossing county or city lines are critical
to the MTS concept. In addition to these links, any link that
accesses major regional activity centers, regardless of trip length
or origin, is also critical in def@g the MTS. The criteria for
determining elements of the MTS should focus on what the different
parts of the MTS do, rather than their geometric design or physical
characteristics. Thus the process for identifying the final MTS
will be based on its various modal components and serve as a multi-
purpose planning tool.

The National Highway System (NHS)

The purpose of the NHS is to provide an interconnected system of
principal routes which will serve major population centers,
international border crossings, ports, airports, public
transportation facilities, and other intermodal transportation
facilities. The NHS is to provide access to ma or travel
destinations; meet national defense requirements; and serve
interstate and interregional travel. Although based on more select
"national importance" criteria, it is clear that the NHS represents
the backbone of the regional system since several criteria used for
identifying the NHS are a prerequisite for those that would be
suggested for identifying the of metropolitan' system.

WSDOT, working in cooperation with the Regional Council, has
proposed a system of routes for this region. Following technical
and public review and discussion, the regional portion of the NHS
was endorsed by the Regional Council in February 1993, and
transmitted to the State Transportation Commission for its
endorsement in April. WSDOT then transmitted the proposed NHS to
the Federal Highway Administration.

System (Approved by FHWA in April 1993).

Other Facilities

State highways (and ferry routes) are inherently of regional
significance since inclusion in the state system requires that
these routes function as the most important inter-regional, intra-
regional, and urban-rural connectors.

Local jurisdictions have identified their most important roads -
principal arterials - based on traffic volumes, VMT, connectivity
to travel generators, directness of travel, and system continuity. 
These principal arterials will be a component of the MTS.

Principal arterials are classified by the state for federal
purposes, and by local jurisdictions for developing comprehensive
or arterial plans. Classification as a principal arterial in either
system denotes a facility of regional significance. Recently, ISTEA
required that all jurisdictions undertake a review of their
federal-aid functionally classified roadways. This review process
was coordinated, endorsed, and transmitted to FHWA by WSDOT and the
MPOs on October 31, 1992. This effort provided the basis for most
cities' classification of their principal arterials.

The Regional Council and its technical review committees are
currently in the process of identifying other roadways that serve a
"regional" function. The task of the committees is to focus on
identifying if any local system non-principal arterials warrant
consideration as having regional significance. Criteria for
defining regional significance will be refined over the next
several months and a consensus will be developed to ensure that the
selection of roadways in this component will be consistent and
equitable throughout the four counties. The review process will
continue until the final draft of the MTP is presented in December
1994. At this time, the Regional Council is recommending that the
following criteria be applied to candidate routes for determining
"regional significance"':

-    Provides important connections for principal arterial system
     continuity.

-    Provides a connection to a major regional activity center or
     travel generator.

-    Serves as a reliever for a freeway or expressway.

-    Serves as a major crosstown arterial for relieving congestion.

-    Serves as an important goods-movement route - if not already
     included in the above components.

-    Provides continuity of access to regional transit transfer
     facilities.

-    Provides major access to a regional port or airport - in
     addition to proposed NHS connectors.


(2) As part of this cooperative effort between the PSRC, WSDOT,
local jurisdictions, and other interested parties, the region must
identify and agree on which local arterials are serving "regional"
functions.


MTP Baseline/Framework Report Background Information          Page 5





-    Provides access to, or incorporates, regional non-motorized
     facilities.

Calculations show that a highway component of the MTS, when based
on the criteria described above, would consist of about 1,500 miles
of highway, and result in 45 million daily VMT. These figures
represent about 9 percent and 62 percent, respectively, of the
total four-county roadway system.(3)


MAJOR OUTSTANDING ISSUES

Setting Future Highway Service Objectives

Given the trend of continued auto use, highway service objectives
need to reflect the probability that demand for private auto use
and consequent VMT will increase if current trends persist. 
Federal and state legislation mandate reductions in VMT growth in
order to meet federal air quality conformity standards. The MTP as
a financially constrained plan will include a limited number of
highway capacity improvements. Approximately 50 - 65 miles of new
"regional highway" additions(4) are currently programmed or planned
for the long-term. Clearly, these improvements can only have a
negligible impact on reducing overall regional congestion. The
short-term Transportation Improvement Program will program funds
according to the most important priorities identified in the
financially constrained plan.

VISION 2020 currently assumes that congestion and delays will
worsen without major changes to the operating environment in which
transportation choices are made. VISION 2020 also assumes that
there will be limited highway-related capacity improvements from a
systemwide perspective. This will mean that most major facilities
may eventually operate well beyond their designed capacity. Some of
the excessive demand may shift to transit and ridesharing. Some
users may seek alternate and often circuitous routes. Some travel
may be distributed into increasingly longer peak periods. Some
travel may be eliminated, particularly discretionary trips that can
be deferred. VISION 2020 recognizes that public policy cannot
control most individual transportation decisions nor can the region
afford to build enough capacity to respond to projected mobility
demands. The MTP must establish service expectations that
realistically represent what can be achieved to support VISION
2020's transportation/growth objectives with a public investment
and policy framework that carefully manages demand and advances
efficiency.

Major issues which will be addressed in the metropolitan
transportation planning process include:

- The Role of the Regional Highway System. The current and future
role of the region's highway system is somewhat downplayed in
VISION 2020. The freeways, state routes, and principal arterials
that comprise the regionally significant system are the backbone of
the region's transportation system and will continue to be for many
years. The issue to be resolved involves clarifying the most
effective role the street and highway system should play in meeting
regional

policy goals in other areas such as economic development and
congestion management.

- Highway Performance Objectives. Current trends indicate
increasing use of and reliance on the private automobile. In
establishing performance objectives for the street and highway
system, the region could assume that current trends will continue
or could develop policy-driven performance objectives based upon
assumptions reflecting a tapering off of future growth in
automobile use. These would include assumptions of a reduction in
the rate of growth for auto travel due to demographic changes,
intervention in the pricing of transportation services, increased
travel options, and applications of new technologies. The MTP
should test the technical and political viability of such
assumptions.

- Deteriorating Service Levels. The MTP is required to be a
financially constrained plan. Relative to other modes, VISION 2020
specifies limited highway capacity improvements on the regional
system over the long-term. Without incorporating major travel
demand management programs, highway improvements and additions
alone would have a negligible impact on overall regional
congestion, as projected future growth will more than offset
planned increases in capacity. Is the region ready to accept and
live with lower system performance in the form of decreased average
speeds, increased delay, and increased congestion for general
purpose highway travel? Most surveys suggest the public is already
aware that this is a future probability.

- The Role of Transportation Demand Management and Transportation
System Management in Accommodating Future Travel Demand. Given that
highway capacity improvements alone will not be able to maintain
current service levels on the region's street and highway system in
the long-term, what changes in public policy are necessary to
integrate demand management and system management into the region's
street and highway planning? A clear statement of performance
expectations for the highway system will be an essential element of
the required Congestion Management System (CMS).

- The Implications of Business As Usual. If the region were to
maintain its present levels of effort in terms of capacity
expansion, demand management, and system management in light of
forecasted population/employment growth, deteriorating service
levels would be inevitable. One default option the region has is to
conduct business as usual and assume that the travelling public
will automatically avail itself of all options that avoid the
capacity "wall". VISION 2020 recognizes that the region cannot
control individual mobility decisions, nor can it afford to build
enough capacity to respond to future travel demand. The
implications of a business as usual strategy for the regional
economy and adjacent counties is unknown. The MTP must set
performance expectations that establish a public policy/investment
framework that realistically represents what can be achieved to
support VISION 2020's growth management/transportation objectives.

- Highway Improvements/Growth Management Compatibility. It is
critical to assure that both state and local transportation system
plans be developed in concert with the MTP, so that the objectives
of all efforts are consistent and mutually supportive. These
transportation plans should address other concurrent planning
activities required under the state Growth Management Act (GMA),
ISTEA, and state and federal Clean Air Acts. The Regional Council,
the WSDOT and local governments will be cooperating on the
development of state highway system



MTP Baseline/Framework Report Background Information          Page 7



performance objectives, standards and ongoing system monitoring
procedures to be part of the final MTP.

- Rural Areas. Where highway widening solutions are proposed to
address safety and existing capacity deficiency concerns in rural
areas, there is a need to evaluate and integrate these solutions
with appropriate plans or conditions for controlled access and
potential local zoning controls to avoid unintended new development
pressures in rural areas. In some cases, there may be a need to
revise conceptual solutions developed by state and local agencies
in highway corridors for different access controls or to defer
development of the highway improvement until coordinated state and
local planning concludes that land use plans are compatible, to
assure maintenance of the rural character. These revisions should
be in concert with broader policy considerations.

Compatibility of Highway Improvements Recommended in the MTP Local
Growth Management Plans.

It is critical that both state and local transportation system
plans be developed in concert with the MTP--so that the objectives
of all efforts are consistent, and mutually supportive. These
transportation plans must address other concurrent planning
activities required under the state Growth Management Act (GMA),
ISTEA, and the federal Clean Air Act. Cooperation on the
development of highway system service objectives, standards, and
ongoing system monitoring procedures is presently being addressed
through a number of forums.
