For air quality dispersion models, mobile source emissions, including both link- and traffic zone-level emissions, must be disaggregated into grid cells. Current gridding methods assign all traffic analysis zone level emissions to the single grid cell containing the TAX centroid. In this study,...

In general, the limitations of the current California vehicle emissions inventory models can be summarized as: - There is no direct connection between the regional emissions inventory model and the gridded emissions model. Separate model runs must be processed to develop regional emissions...

Previous analysis of bottleneck congestion and departure time choice have focused on the trade-off between queuing delay cost and early/late arrival penalty for a given work start schedule. The actual scheduling of travel and work activities may well depend on some other important factors, such...

We present in this report a new car-following theory that can reproduce both the so-called capacity drop and traffic hysteresis, two prominent features of multi-phase vehicular traffic flow. This is achieved through the introduction of a single variable, driver response time, that depends on...
