The Metropolitan Transportation Plan (MTP) for Clark County is the region's principal transportation planning document. It represents a regional transportation plan for Clark County, developed through a coordinated process between local jurisdictions and transportation agencies in order to develop regional solutions to transportation needs.
MTP document downloads are available from the main MTP page.
Transportation Systems Management and Operations (TSMO) strategies focus on lower cost operational and multimodal approaches that are coordinated between technologies and agencies to make better use of existing transportation facilities. These strategies are directed toward improving system efficiency and performance without adding new roadway capacity. They support regional transportation goals by improving travel time reliability, reducing crashes, improving transit on-time performance, and by reducing travel delay, fuel use, and air pollution. TSMO strategies can include a wide range of projects such as: traveler information, freeway management, arterial management, coordinated incident management, and transit signal priority.
The Regional Transportation Systems Management and Operations Plan for Southwest Washington, adopted by the RTC Board in June 2011, sets the policy and performance guidelines, a 10-year TSMO project plan, and a set of transportation corridors for the consideration of regional operational strategies in Clark County.
The full TSMO Plan is 109 pages long is 4.0 Mb.
Also available is a 14-page Executive Summary and the plan's Regional Intelligent Transportation Architecture.

The federal transportation act, SAFETEA-LU, requires development of a Coordinated Human Services Transportation Plan (HSTP). The HSTP addresses the transportation needs of the elderly, people with disabilities, low income populations, and rural residents unable to provide transportation for themselves. The first Human Services Transportation Plan for Clark, Skamania and Klickitat Counties was adopted by the RTC Board of Directors on January 2, 2007. The adopted 2010 HSTP update supports grant requests submitted by this region for state and federal funding for human services transportation needs through the Washington State Department of Transportation's statewide competitive Consolidated Public Transportation Grant program.
The Final Report (PDF, v7) is 123 pages and the download is 2.8 Mb. The Report includes RTC Board Resolution 12-10-25 signifying the Board's approval of the Plan update and the latest listing ranked human services transportation projects from RTC's three-county Regional Transportation Planning Organization region.
The Clark County High Capacity Transit System Study report is the culmination of a two-year effort, on the part of RTC and its partner agencies, to develop a High Capacity Transit (HCT) System Plan. The plan includes bus rapid transit (BRT) in the Highway 99, Fourth Plain, and Mill Plain corridors and significant bus improvements in the I-205 corridor. The plan will serve as a guide for C-TRAN and the communities in Clark County as they move forward with improvements in the planning of future HCT Corridors. The Final Report, System Plan Map, and numerous other related documents, maps and factsheets are available online for your review in the Documents section of this study's Information page.

InterACT, a subsidiary of Identity Clark County (a private, non-profit organization focused on community and economic development), recognized an impending implosion of voter financial support for Clark County’s transportation system and elected to take on a project that enabled its citizens to dream it, fund it, build it. Their findings detail how the project was conceived, designed and executed, and documents the results. The “Additional Information” provided as attachments to the report capture direct comments/concerns from the jurisdictions prior to launching the project, actual text of polling questions used, keypad technology polling results, a transportation briefing document (educational piece), direct citizen input comments, and jurisdiction reactions to the project.

The purpose of the study was to develop project recommendations along the corridor to improve safety, by reducing weaving, and increase or maintain the levels of service along the section of I-205 between SR 14 and NE 83rd Street. The recommendations include provisions for new access locations and the modification to existing access locations. The Access Point Decision Report was published and submitted to the Federal Highway Administration (FHWA) to gain federal approval for these project recommendations.

The I-5 HOV Corridor Operational Study investigated the feasibility and operations of a bi-state HOV facility in the I-5 corridor. The study was conducted in two phases. The first phase analyzed and identified a range of feasible HOV lane configurations for detailed operational analysis. While Phase I examined several configurations, the key to this portion of the study was an assessment on the feasibility of a reversible lane across the Interstate Bridge that will allow new HOV capacity without reducing general purpose capacity. The second phase of the study was the development of an HOV implementation plan. Phase II included a micro traffic operational analysis, the development and design of an HOV lane configuration in the I-5 corridor, an estimate of capital and operating costs, and a public information program, including a Clark County transportation survey.
The Final Report (PDF) is 100 pages and the download is 1.7Mb. The I-5 High-Occupancy Vehicle Operational Study Executive Summary with Technical Advisory Committee Findings (HTML) is also available online. The study concluded with a recommendation to implement a southbound high occupancy vehicle lane in the corridor during the morning commute period in conjunction with the I-5 widening construction project. The Vancouver HOV Lane Project is scheduled to open in Fall 2001.
Nowhere in the region is the cost of delay more apparent than on Interstate 5 from Portland to Vancouver. Interstate 5 is critical to the regional, state, and national economy. It is the most significant freight freeway on the West Coast linking markets in Canada, the United States, and Mexico. It is also the busiest commuter roadway in the region, linking the region's two largest cities.
The region's transportation policy-makers appointed a 14-member Leadership Committee and asked them to examine the problems in the I-5 Trade Corridor and to address the following questions. What is the magnitude of the problem? What are the costs of inaction? What improvements are needed? How can they be funded? What are the next steps? This report is the Leadership Committee's response to the charge.

The purpose of the study was to develop a High Occupancy Vehicle region-wide system plan for Clark County that defines policies and objectives, identifies the need and benefits, and identifies the location of possible corridors and/or facilities. HOV lanes are travel lanes that are dedicated for use by carpools or buses; they are essentially for use by vehicles that carry more than one passenger. An HOV program can improve overall mobility in the most congested parts of our region by increasing the people-moving efficiency and capacity of freeway and arterials.
The study recommendations are made up of three elements: 1) goals and policies of a Clark County HOV System, 2) HOV System Plan, and 3) next steps, including a detailed examination for the implementation of an HOV facility in the I-5 corridor.
