A freeway corridor consists of the freeway and its entrance/exit ramps, the cross streets, and adjacent parallel arterial streets. It is designed to provide a generally high level of service (LOS) to their users and to the communities which they serve. However, many corridors in the country are congested, with the worst congestion problems usually arising during the two peak periods(morning and evening) (Schrank and Lomax, 1999). =There are two types of traffic congestion observed: recurrent and non-recurrent. Recurrent congestion are due to excessive peak demands and non-recurrent...

Demographic forecasts suggest that these patterns will continue. California will continue to attract immigrants from throughout the world and will become increasingly diverse, racially and ethnically, with whites declining as a share of the population from 54 percent in 1995 to 30 to 34...

Augmented Speed Enforcement Project at PATH: Minimizing Hazards in Work Zones in Rural Areas

California PATH
2013

The Partners for Advanced Transportation Technology (PATH) developed, implemented, and field-tested an Augmented Speed Enforcement (aSE) system that will help enforce reduced speed limits in construction zones and thereby protect personnel working in the road-way. The work was conducted under a project sponsored by the United States Department of Transportation (USDOT) with collaboration from California Department of Transportation (Caltrans), California Highway Patrol (CHP), and Western Transportation Institute (WTI) of Montana State University. The project was carried out with the goal...
