Abstract

Most of geographical phenomena studied in Geographical Information System (GIS); involve with some changes in time. Considering temporal changes is of prime importance in any GIS modeling. Such consideration enforces the development of SPATIO-TEMPORAL GIS that is one of the active research areas nowadays. These systems automatically apply the changes occurred on the data to GIS models and update them accordingly. One way to consider the changes is to use a suitable POSITIONING method in a SPATIO-TEMPORAL GIS to be customized for INTELLIGENT TRANSPORTATION SYSTEMs (ITS). This paper aims at identifying the most suitable POSITIONING method for ITS in IRAN and then aims at designing a SPATIO-TEMPORAL GIS Based on it.Positioning methods can be classified into four categories, namely; satellite POSITIONING, Inertial Navigation Systems (INS), POSITIONING on the vehicle and POSITIONING through communication networks. Selecting a suitable method requires to identify the governing factors and their influence on POSITIONING. Disregarding each of them may cause system restrictions.This paper evaluates the mentioned POSITIONING methods and selects the most suitable method for IRANian territory. Based on the evaluations, Global POSITIONING System (GPS) was selected as the most suitable POSITIONING method in IRAN. The paper is then concentrated on developing a SPATIO-TEMPORAL GIS with emphasis on finding optimum path based on the shortest time-distance in real-time automatically. For this purpose, trajectories of vehicle motions were recognized by using spatial and aspatial information in the first step.Secondly, the position of the vehicle was navigated by GPS that was enhanced by a map-matching process. Finally, a real-time route finding algorithm was used for dynamic updating of planned vehicle trajectory.The proposed system has two invoations. The first is in selecting the most suitable POSITIONING method for IRANian territory and the second is the introduction of a SPATIO-TEMPORAL GIS (STGIS) functionality for Dynamic guidance of the vehicles. Using STGIS, which is equipped with analytical capabilities, will provide more facilities for guiding vehicles. For example with STGIS, further extensions such as controlling autonomous vehicle for avoiding or leaving the banned regions are doable.This paper concentrated on determining the most suitable POSITIONING method for INTELLIGENT TRANSPORTATION SYSTEMs in IRAN and then aims at designing a SPATIO-TEMPORAL GIS Based on it. The proposed system was entirely designed by authors successfully and has the abilities of editing, map matching and Spatio- Temporal route finding based on minimum distance and time. Other researchers can improve the system operations by using other Spatio- Temporal functions such as alarming vehicle entrance to prohibited zones.
