In this paper, the route selection system of heavy-cargo highway transportation was the secondary developed based on ArcGIS Engine . The spatial data platform was set up by simulating the actual road network, and combined with quantitative analysis of the influence factors, a route planning model of double objective was established. Finally, the optimal route was determined by using ArcGIS network analysis technology. Introduction The selection of transport routes is the major work in the early period of heavy-cargo highway transport. The optimal transportation lines can be quickly and scientifically determined by using the computer technology, which will greatly shorten the construction period and cost savings.As a computer system,GIS is used for collection,simulation, processing,query retrieval,analysis and expression of geographic data,and it has strong capability of spatial information processing and spatial data analysis. In this paper, the route selection system of heavy-cargo highway transportation is redeveloped based on ArcGIS and Visual studio 2010. The spatial data platform was set up by simulating the actual road network, then the transportation time, cost and safety factors of evaluation index can be written into the property field based on the arc-node topological data structure, and a certain weight of road network can be gotten.Combined with quantitative analysis of the influence factors, the multi-objective optimization model based on route is established, and the multi-objective optimal path and graphical display are gotten by adopting the platform of network analysis module. Establish the model of route selection of heavy-cargo highway transport Influence factors of route selection of heavy-cargo highway transport. According to the special requirements of heavy-cargo highway transport, the main factors of affecting the transport route selection are clearance restrictions of route, road pavement and administrative restrictions.Clearance restrictions mainly refers to the space restrictions in height and width, Road pavement restrictions mainly refer to the minimum curve radius and ramp,road pavement and bridges\dams loading capacity that required by vehicles and equipment in the transport route. Administrative restrictions mainly refer to the constraints of heavy-cargo transportation vehicles and equipment during transporting by relevant transport regulations of local transport authorities.When the actual route selection was conducted, in addition to the above factors, economically feasibility, the shortest time as well as the shortest transportation distance and other factors should also be taken into consideration, so that the transport task can be completed economically, efficiently and safely. Building model.When making heavy-cargo highway transportation, there are usually a variety of transport routes between origin and destination.Supposed that there are N cities from origin to destination, and every two adjacent cities are viewed as a road section,then a road network can be 3rd International Conference on Materials Engineering, Manufacturing Technology and Control (ICMEMTC 2016) © 2016.
