Comparison of using different kinds of traffic data in best route analysis based on GIS
Abstract
Geographic information systems (GIS) represent a sophisticated tool in transportation network analysis. It is very important how transportation network is modelled regarding traffic data. Usually, fixed travel speed data is used, but due to advancements in information and communication technologies (ICTs) and location-aware technologies (LATs), it is now possible to collect large amounts of mobility and activity data in real-time. The aim of the paper is to make a comparison between different types of best route analysis regarding different travel speed information: fixed travel speed, historical traffic, and live traffic. This finding would not be important only for best route analysis but also for other types of network analyses. First, we distinguish between different kinds of travel speed information, then we present our practical work of creating three different types of network models according to different types of traffic speed data, and finally we perform best route analysis along the above models and compare the results.
