Texas Ranking of Interchange Projects: Trip, PC Interchange and RR Grade Separation Benefit-Cost Program

摘要

The report documents a PC computer program that will analyze proposed interchange, railroad grade separation, and bypass projects. The Program is called TRIP, Texas Ranking of Interchange Projects. The evaluation includes calculations of motorist savings in user costs over a planning period. These user costs include delay costs, vehicle operating costs, and accident costs. The final output is a benefit-cost ratio. TRIP is a menu driven program that includes a data input and editing process, data analysis, output display, and procedures to save both the input and output data. The menus allow for changes and modifications of the data at any stage, and a great deal of flexibility in changing the assumptions used to make the calculations. The methods used to input data, analyze a problem, and output the results are described in the report. The user cost calculations are described, along with an example of the input and output.
