Return to Travel and Land Use Forecasting  Travel and Land Use Forecasting    Project Summary :: 1  2  3  4  5   EIS & Toll Feasibility Study – Mountain View Corridor, Utah Project Background To address enormous anticipated growth and projected local and regional transportation demand in western Salt Lake County and western Utah County north of Utah Lake, the Federal Highway Administration and Federal Transit Administration, in cooperation with the Utah Department of Transportation, the Utah Transit Authority, Mountainland Association of Governments and the Wasatch Front Regional Council, are preparing the Mountain View Corridor Environmental Impact Statement. Several options are being considered, including the option of using tolls to manage demand and help finance construction and maintenance of a new roadway. Project Scope Resource Systems Group (RSG) was contracted to provide toll modeling expertise and to enhance the regional travel demand model to enable analysis of High-Occupancy Vehicle (HOV), High-Occupancy Toll (HOT), and dedicated toll-way demand in the region. Specific model enhancements included: •  Implementing advanced practice trip distribution models that were sensitive to more than general purpose auto travel time. RSG implemented a home-based-work destination choice model and non-work gravity models that utilized composite impedance. •  Expanding the nested logit mode choice model to consider toll and HOV highway travel separately from general purpose lane highway travel. The toll/non-toll choice is inherently a route choice decision, sensitive to relative travel times, costs and trip lengths. •  Reviewing and improving the network skim builder so that the potential toll market is adequately represented, reasonable toll paths are built and the mode choice modeling can be done with confidence Project Results The toll feasibility analysis is currently finishing up. The model was used to analyze and recommend toll road feasibility, phasing, and revenue potential. Utilizing the mode choice model for understanding toll demand is particularly useful because it allows for toll demand to be tracked and critiqued for reasonableness by trip purpose, trip length, and income, for example. The modeling system will be a valuable tool for the region as it moves forward with further long-range toll studies.
