Benefit Summary HTML

This project was initiated by Caltrans, looking to increase throughput on four HOV lanes (express lanes) on a seven-mile section of the I-15 in San Diego County. The study evaluated the implications of converting the concrete median that separates the express and regular lanes into a nine-foot automated vehicle (AV) exclusive reversible lane. The study conducted an extensive literature review, an AV manufacturers product review, expert interviews, a consumer questionnaire review, a crash data analysis, and a microscopic traffic simulation analysis. The microscopic simulation model, developed in a commercially available software package, was used to evaluate the impact of the exclusive AV lane on traffic conditions under different market penetration rates (MPR).
