D1−1: Multi−Level Transportation Management Plan (TMP)

DESCRIPTION:

The goal of a Transportation Management Plan (TMP) is to proactively manage the traffic−related impacts of a construction project. TMPs manage impacts through the application of traditional and innovative traffic mitigation strategies. A project−level TMP is required for every Federal−aid highway project by the 2004 Work Zone Safety and Mobility Rule (http://www.ops.fhwa.dot.gov/wz/resources/final_rule.htm). A multi−level TMP coordinates these efforts for several work zones across a city, region, or State. A multi−level TMP is particularly useful when several road projects may be occurring at the same time and have a compounding effect on traffic and mobility in a region. Multi−level TMPs build off of one another, with the higher level TMP setting policies for the lower−level TMPs.

The Oregon Department of Transportation (ODOT) developed a multi−level TMP approach to address safety and mobility at a regional and statewide level, recognizing that motorists may encounter multiple work zones on a trip and the combined impacts of those work zones may add up. This approach improved ODOT's ability to identify potential mobility or safety issues earlier, and provide proactive, coordinated solutions. Oregon uses three levels of TMPs: program−level, corridor−level, and project−level. Oregon's program−level TMP serves as the framework for corridor−level TMPs, providing overarching safety and mobility policies for the State. Oregon's corridor−level TMPs identify corridor management, construction staging, and mobility strategies for six high−volume freight and passenger travel routes. Lastly, Oregon's project−level TMPs describe traffic control, congestion mitigation, and public information/outreach strategies for individual projects.

A similar approach is being used for the Virginia Megaprojects program. The program is a Virginia Department of Transportation (VDOT) initiative to develop, facilitate, and use coordinated transportation management strategies for several major regional mobility projects in Northern Virginia, just outside the Nation's Capital. Projects include construction of high occupancy toll (HOT) lanes along I−495, widening of I−95 and I−66, expansion of the Metrorail system from downtown Washington, DC to Dulles airport in suburban Virginia, and other spot improvements across the region. Each specific project proposed under the Megaprojects banner developed its own independent TMP. VDOT also developed a regional TMP to analyze the overarching impacts of these individual project TMPs on mobility throughout the Washington, DC metro area. In creating the regional TMP, VDOT identified the combined impacts of the projects and potential areas of conflicts or excessive impacts, and met with stakeholders to resolve those issues. Methods were proposed to alleviate concerns through shared mitigation strategies. The regional TMP provided VDOT with a framework to monitor conditions and quickly implement or modify impact management strategies as needed.

REASON(S) FOR ADOPTING:

When developing complex large−scale projects, a multi−level TMP can provide a comprehensive analysis of the cross−cutting impacts that a series of simultaneous projects will have on one another and coordinate the efforts to manage the impacts. It can also identify the smaller−scale impacts that each project will likely have on mobility and safety in the surrounding community.

PRIMARY BENEFIT(S):

Reduced overall impacts from better coordinated projects that consider the safety and mobility impacts each project will have on others in the region and the combined impacts that projects will have on motorists, businesses, and other stakeholders. Potentially increased efficiencies and reduced costs for traffic management strategies since some strategies (e.g., a motorist assist program, CCTV, variable message signs) may be suitable for sharing across projects.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

Regions where multiple projects will be occurring simultaneously that could affect mobility through the region. Multi−level TMPs are also applicable for large scale rehabilitation and construction projects that impact entire corridors, regions, or States.
