THE NEW HAMPSHIRE STATEWIDE TRAVEL MODEL SYSTEM

The New Hampshire Statewide Travel Demand Model System (NHSTMS) was developed as part of the Statewide Planning Study. The model will help predict travel behavior (i.e., how people travel - by car, bus, etc.) and travel demand (i.e., how many people want to travel on a certain road or by a certain mode). The model is based on statewide data collected on highway, bus, rail and airport systems; and land use, social and economic characteristics. Household travel, roadside motorist, and transit rider surveys were conducted as part of the data collection effort. The New Hampshire Department of Transportation and its consultants plan to use the model to identify potential new or improved transportation services and strategies, designed to improve overall transportation services, reduce congestion and improve air quality. This paper describes the NHSTMS and how it works. Following an introductory section, the next section describes the objectives of the model system. This is followed by a summary of the model structure. Section four discusses the data requirements of the NHSTMS. Section five describes the zone system and networks in the NHSTMS. Section six provides a detailed discussion of the trip table creation, mode choice, and assignment processes, and Section seven describes the database and Geographic Information System features of the model system.
