TRB's Airport Cooperative Research Program (ACRP) and Transit Cooperative Research Program (TCRP) have released a joint report, ACRP Synthesis 91 / TCRP Synthesis 137: Microgrids and Their Application for Airports and Public Transit. The report describes microgrids that airports and public transit agencies can implement to increase resilience of their critical infrastructure. A microgrid is described as a collection of loads, on-site energy sources, local energy storage systems, and an overarching contro...

TRB’s Transit Cooperative Research Program (TCRP) Web-Only Document 44: Literature Review for Providing Access to Public Transportation Stations describes the results of the literature review examining various alternatives for providing access to and from stations of new and mature high-capacity public transportation systems, including heavy rail, light rail, commuter rail, and bus rapid transit. In 2012 TRB released TCRP Report 153 : Guidelines for Providing Access to Public Transportation Stations, whi...

TRB’s Transit Cooperative Research Program (TCRP) Research Results Digest 89: Public Transportation’s Role in Addressing Global Climate Change provides an overview of an International Transit Studies Program mission that investigated public transportation’s role in addressing global climate change in several cities in Ireland, Germany, Italy, and Spain.

TRB’s Transit Cooperative Research Program (TCRP) Synthesis 80: Transit Security Update explores transit-related counterterrorism and anti-crime security measures and practices; examines crime and security incident trends; and highlights other related topics, including major issues and obstacles to security and policing management.  The report is an update to TCRP Synthesis of Transit Practice 21: Improving Transit Security, which did not address terrorism.

TRB’s Transit Cooperative Research Program (TCRP) Synthesis 79: Light Rail Vehicle Collisions with Vehicles at Signalized Intersections explores mitigation methods tested and used by transit agencies to reduce collisions between light rail vehicles (LRVs) and motor vehicles where light rail transit (LRT) runs through or adjacent to highway intersections controlled by conventional traffic signals.

TRB’s Transit Cooperative Research Program (TCRP) Research Results Digest 91: Synthesis of Information Related to Transit Problems is a digest of the progress and status of TCRP Project J-7, “Synthesis of Information Related to Transit Problems,” for which the Transportation Research Board is the agency conducting the research.

TRB’s Transit Cooperative Research Program (TCRP) Synthesis 77: Passenger Counting Systems explores analytical tools and technologies for collecting transit ridership and other subsidiary data. The report also examines issues of potential concern to transit agencies considering automatic passenger counter systems.

TRB’s Transit Cooperative Research Program (TCRP) Synthesis 78: Transit Systems in College and University Communities has released a report that explores practices and trends in the areas of campus transit operations, policies, and planning, with a special focus area in technology and environmental innovations.  The report also examines innovative partnership strategies used to enhance services for students, faculty, staff, and the surrounding community.

TRB’s Transit Cooperative Research Program (TCRP) Legal Research Digest 28: Uses of Fees or Alternatives to Fund Transit explores the use of impact fees for transit in the United States.  The report examines policy and legal considerations relating to the use of impact fees and developer exactions for transit, reviews various methodologies currently in use, and identifies cases that exemplify strategies transit agencies may pursue when considering impact fees as an alternative funding source.

TRB’s Transit Cooperative Research Program (TCRP) Synthesis 76: Integration of Paratransit and Fixed-Route Transit Services explores the experiences of transit agencies that have attempted to depart from the traditional binary model of separate fixed-route and paratransit services by seeking a variety of ways to integrate their services.  Options examined in the report include the provision of paratransit feeder services, community bus or circulators, connectors, fixed-route fare incentives, ...
