چکیده
This report describes unique surveillance system on a section of I-80 freeway in the city of Emeryville. The system, called the Berkeley Highway Laboratory (BHL), consists of eight dual loop detector stations along the freeway section, and 12 video cameras. Advanced machine vision algorithms were developed to process the video data to generate vehicle trajectories. Efforts are underway to fuse the loop and video detector data to obtain detailed and accurate information on traffic operating conditions

One source of vehicle conflict is the freeway weaving section, where a merge and diverge in close proximity require vehicles either entering or exiting the freeway to execute one or more lane changes. Using accident data for a portion of Southern California, we examined accidents that occurred on three types of weaving sections defined in traffic engineering: Type A, where every merging or dive...

This paper develops an economic framework for developing strategies necessary to deploy networks, and applies the framework to the deployment of road pricing. The cost structure of highways are discussed. A graphical method for measuring welfare with road pricing is presented. The relationship of space and financing mechanism is reviewed. A network model of the economy is presented. This is fol...
