Intelligent Transportation Systems (ITS), ushered in by ISTEA in 1991 and advanced under TEA-21 in 1998, fundamentally alter transportation planning and implementation in the United States. ITS shifts emphasis away from new construction and capacity to more efficient management of existing systems, in the process requiring increased coordination and integration of standards, systems, and policies. The National ITS Architecture provides a framework for integration, but leaves the majority of the implementation decisions to the state, regional, and local levels. California is well-positioned...

The purpose of this research is to assess the effectiveness on individual travel behavior as a result of using combined car-sharing and transit passes. This assessment was based upon participation in a mobility pass program or Compass + Pass Program that was implemented in late 2004 in the San Diego region. Program participants were highly satisfied for having an alternative to the drive-alone commute. This key finding points to the fact that there is some level of latent demand for alternatives to the drive alone commute, especially in corridors with heavy peak hour congestion. Also of...

Quality data collection, processing, and analysis are foundational to good research, policy making and regulation development. With the rapid development of Connected Automated Vehicles (CAV) technologies, it is urgent for both researchers and policy makers to obtain and evaluate good quality CAV data to better understand CAV impacts. CAV hardware-in-the-loop (HIL) tests can expedite CAV performance evaluation and system implementation. This research aims at equipping an existing HIL test tool with data management functions. To this end, a database instance on MySQL has been integrated...

This report has been prepared as the final deliverable for a research project developing a combined quantitative and qualitative approach to planning for improved intermodal connectivity at California airports. The quantitative approach involves the development of an Intermodal Airport Ground Access Planning Tool (IAPT) that combines transportation system performance measurement, an air passenger mode choice model, and a model of transportation provider behavior, and is designed to interface with a traffic network analysis model. The qualitative approach is used to enhance the quantitative...
