Abstract

Highway geometric design is part of planning process design for physical highway to fill up basic function of roads, to give good traffic service from one place to another. The important component of highway geometric design is selection of a minimum cost route which involves careful planning, design, right-of-way acquisition and construction. The characteristics of traffic flow, size of vehicle, driver's behavior, sight distance, super elevation and topography are the variables of highway geometric design after determination of the economy route and safety. It is not easy to select an economical route by manual design because a good proposed route should involve a complex design processes such as detailed assessment of geographic features, potential land use for road construction and environmental evaluation. Therefore, Geographic Information System (GIS) is a potential solution for acquiring detail information for design process. In this research, a computerized highway design model based on GIS is proposed to assist in evaluation of several alignment alternatives. A knowledge-base expert system was developed with acronym of ES-HGDesign using shell expert system of KAPPA-PC Version 2.4 that is object oriented and displaying higher graphic resolutions. The study stresses on the provision of design output and suggests road alignment based on the accumulation of knowledge from several experts, collecting data, reading literature and reports, discussions with domain experts, case studies by applying a modular approach. Normally, the process geometric designs are carried out by experts. The design process was computerized and apply artificial intelligent to provide a system that give decision and suggestion for the best route alignment.
