A computer model for economic evaluation of road user costs in urban road projects

The paper describes the author's version of a group project. The objective is to determine the present worth of traffic costs on one section of an urban road. Variables include running section of road, signal and uncontrolled intersections, pedestrian and rail crossings, six vehicle types and occupants. Running times and delays are accumulated and a cubic travel time flow relationship is derived for the range from zero to capacity flow. The pelensky linear unit cost model is used. Annual cost is obtained by integrating over a polynomial hourly flow frequency distribution for the year. Traffic growth over the years is allowed in linear or exponential manner and costs are discounted to present worth. A novel approximation is used to estimate costs if future traffic grows beyond capacity. Accident costs can also be estimated. A similar treatment is available for motorways (a).
