STOPS Model Development and Forecasting San Diego Metropolitan Transit System (SMTS) Transpo developed forecasts of ridership for public transportation projects within the SMTS service area, which supported their long-range planning effort. The projects ranged from the implementation of service patterns on new routes (e.g. aerial tramways and trolleys) to improved transit service frequency across multiple routes. STOPS was calibrated to match SMTS’ systemwide boardings, route-level boardings, and ratio of unlinked to linked trips. Following model calibration, the model was used to develop ridership forecasts for each of the proposed new or improved transit services. I-5 DTA Modeling Service Washington State Department of Transportation Transpo developed, and continues to apply, an innovative mesoscopic Dynamic Traffic Assignment (DTA) Model for this I-5 corridor. This project also includes parallel and intersecting state routes in the vicinity to enable testing of a wide variety of alternative routing options. Proposed treatments simulated with the DTA model include ramp meter installations, interchange ramp re-configuration/re-alignment, and HOV-lane additions. The DTA model is capable of analyzing traffic conditions under many different geometric and operational scenarios, such as lane reconfiguration, new intersection controls, new roadway connections and improvements.
