TCRP Report 173: Improving Transit Integration Among Multiple Providers presents a comprehensive set of guidelines and procedures to assist transit agencies in evaluating, planning, and implementing steps to integrate transit services in areas with multiple transit providers. The report comprises two volumes: the Transit Integration Manual and the Research Report. Together, these documents can help guide the process of transit service integration by (1) showing the benefits of integration; (2) illustrating the range of potential types of integration activities; and (3) describing procedures necessary to carry out integration efforts, including tips for success.

This report will be of interest to transit operators, metropolitan planning organizations, and others interested in the coordination and integration of transit services to improve customer service in areas with multiple transit providers.

Today’s airport practitioners need easy access to the tools that will keep their facilities open and thriving. In this era of uncertainty, the Airport Cooperative Research Program (ACRP) serves as a source of unbiased, accurate research to assist the industry. ACRP is an applied research program managed by the Transportation Research Board of the National Academies and sponsored by the Federal Aviation Administration. Together with public- and private-sector industry experts, ACRP produces reports, syntheses, and digests that cover a diverse set of research fields: safety, policy, planning, airport design, construction, legal issues, maintenance, operations, and administration.

The shift in the airport industry—from predictable traffic and passenger levels to economic instability, capacity constraints, and congestion—has required airport practitioners to respond with creative problem solving. ACRP has been offering practical, hands-on software guidance, modeling tools, sample planning documents, best practices, worksheets, checklists, and more since 2006. Critical to ACRP’s success has been its ability to establish and engage with a growing network of airport practitioners. Over the past nine years, industry experts representing all 50 states, Washington, D.C., and Puerto Rico, have contributed to the program’s research and helped ensure that ACRP’s work is relevant and meaningful to its audience.

This research aims to determine the relationship between driver inattention and crash risk in lead-vehicle precrash scenarios. It seeks to develop inattention-risk relationships describing how an increase in inattention performance variables combines with context in lead-vehicle precrash scenarios to increase risk. The inattention-risk relationships are intended to show which glance behaviors are safer than others and pinpoint the most dangerous glances away from the road. The results should support distraction policy, regulation, guidelines; improve intelligent vehicle safety systems; and teach safe glance behaviors.

TRB’s National Cooperative Freight Research Program (NCFRP) Report 31: Incorporating Truck Analysis into the Highway Capacity Manual presents capacity and level-of-service techniques to improve transportation agencies’ abilities to plan, design, manage, and operate streets and highways to serve trucks. The techniques also assist agencies’ ability to evaluate the effects of trucks on other modes of transportation.

These techniques are being incorporated into the Highway Capacity Manual, but will be useful to planners and designers working on projects with significant truck traffic.
