FEASIBILITY AND DEMONSTRATION OF NETWORK SIMULATION TECHNIQUES FOR ESTIMATES OF EMISSIONS IN A LARGE URBAN AREA

The objective of this study was to investigate the possibility of using microscale network simulation computer models to estimate motor vehicle activity for a large urban area. Existing network simulation models are capable of resolving vehicle activity down to the individual vehicle level, and are used to study traffic movements for small areas such as intersections or short sections of highway. Regional travel demand models have historically not been used for the purpose of emissions estimation, and thus poorly define elements of vehicle operation such as accelerations and decelerations. The contractor was to investigate the feasibility of adapting existing microscale models to produce regional estimates of vehicle activity for the Eastern Bay Area region of northern California, due to 'sampling approach' which actually modeled only a subset of region and used this 'sample' as a surrogate for modelling the entire region. Within this constraint, the contractor successfully adapted existing models and developed 'post-processing' software to produce aggregate estimate accelerations, decelerations, cruises, and idle for the Bay Area region modeled.
