A Gis-based Modelling of Vehicles Rational Routes

Methods of searching the rational route are dealt with in the presented article, where the main optimality parameters of the route are chosen: the shortest travelling route (1), the fastest travelling route (2) and the alternatively selected route (3), where the optimality criteria are calculated for one‐side traffic swath. Based on analysed aspects, GIS tools for transport flow modelling are picked and route search algorithm resulting in evaluation of the road permeability depending on the time of the day designed. Such methodology is based on real adaptability example in one transport area of Vilnius city.
