The report describes the findings of a study to develop a simulation testbed for the Santa Monica freeway corridor. The study created one of the largest freeway corridor networks coded for the CORSIM microscopic simulation model. The coded network consists of about 10 miles of I-10 freeway and a...

This report presents the findings of a feasibility study which developed a simulation testbed for the Santa Monica freeway corridor. The study involved performing an evaluation of the state-of-the-art models for Advanced Traffic Management and Traffic Information Systems (ATMIS) on freeway...

This study looked at the operations and functions performed at the Caltrans Transportation Management Centers (TMC) with focus on the data sources, data processing, and performance measures. Recommendations are made for making greater use of archived real-time archived data. These include...

Traffic responsive control strategies are increasingly being implemented to improve intersection performance. Critical intersection control (CIC) is using real-time traffic data to better assign green times to conflicting movements. However, the benefits of CIC have not been assessed, and...

Freeway collisions are thought to be affected by traffic states. To reduce the number of collisions, the study to reveal how the traffic states influence collisions are required. Therefore, the purpose of the paper is to suggest a method to relate traffic states to collision frequency in...

The paper describes a methodology and its application to measure total, recurrent, and non-recurrent (incident related) delay on urban freeways. The methodology uses data from loop detectors and calculates the average and the probability distribution of delays. Application of the methodology to...
