This report documents a research effort to understand the current practice and issues associated with Bus Rapid Transit (BRT) planning and deployment. It reviewed the design options incorporated into existing BRT deployments across California and the nation. The project team interviewed...

This report addresses Transit Signal Priority (TSP) deployment issues. It reviews National Transportation Communications for ITS Protocol (NTCIP) 1211 Signal Control and Prioritization (SCP) standards, defines five SCP scenarios, and describes how the SCP scenarios can be applied differently...

This research demonstrated two potential VII (vehicle-infrastructure integration) services, one in traffic data probes and the other with safety. A real private vehicle, operating on California roadways, “talked†to the roadside, with the roadside backhaul interfacing into an existing...

The California Department of Transportation (Caltrans) is developing a virtual weigh and compliance system (VWCS) for better commercial vehicle monitoring and weight enforcement. The objective of this synthesis is to document recent efforts and technologies associated with the automated...

Employment and the journey to work have long been a focus of transportation study. Although today, the work trip accounts for a much smaller share of total trips than it did a few decades ago, there are several reasons why this subject deserves our continued attention. In planning for the...
