Deployment of Prior HOV Lanes Research Results in Developing Analysis Tools for New Managed Lanes Projects.

摘要

The Center for Environmental Research and Technology (CERT) at the University of California, Riverside, successfully completed a previousnresearch on the effectiveness of high-occupancy vehicle (HOV) lanes at improving air quality for the California Department of Transportationn(Caltrans). As part of that research, analysis tools were developed to evaluate the air quality benefits of limited access HOV lanes, which arencommonly found in Southern California. This project used researcher(s) unique skill sets in vehicle activity data collection, traffic simulationnand emission modeling as well as extensive experience in this research area to expand the capability of the developed tools to enable airnquality impact evaluation of the other types of managed lanes, including continuous access HOV lanes (commonly found in NorthernnCalifornia) and high-occupancy toll (HOT) lanes. These enhanced analysis tools will allow Caltrans’ technical staff to compare emissionnimpacts of projects involving the addition of new lane(s), either general-purposed (GP) or any type of managed lanes, or the conversion ofnexisting lane(s) from one type to another against the no-build and other alternatives. The analysis tools will be compatible with the California’snEMFAC model, and will be in a spreadsheet platform which is easy to use by Caltrans’ technical staff. In addition, prepared user’s guidendocumentation and conducted user training in order to ensure an effective knowledge and technology transfer to Caltrans.
