Transportation and Communication

MOTORS is a comprehensive package for planners and decision makers concerned with all phases of highway and transit planning. The programs in MOTORS can model both small traffic management projects and large ones covering whole transportation corridors, cities, regions, or even entire countries. For convenience, the MOTORS programs are divided into five categories: demand modeling programs, matrix programs, highway network programs, transit programs, and utility programs. The highway network programs are used to simulate highway networks using link-and-node formats, to find minimum paths, and to carry out operational evaluations on networks. Inputs to the highway network programs include: travel time, link length, link speed, link capacity and capacity class, percentages of peak volume, link classification, and link jurisdiction. The Quick Benefit-Cost Procedure estimates the benefits of a proposed highway project as the difference between projected operating and travel-time costs under conditions before and after construction of the project.
