Abstract

In urban planning, the development of the city for the future must be controlled. Therefore, in the city planning phase, it is necessary to plan for all events, from meteorological conditions, weather pollution, and settling to traffic accidents, according to potential future requirements. Road maps produced using statistical methods must be the base products for city planning. This study develops methods to obtain maps to determine traffic hot zones in Konya, Turkey, by applying Spatial Analyst (SA) supported by Geographical Information Systems (GIS). In this study, unlike preceding studies, the aim is to determine new safe routes and zones with the help of GIS. Another, different aim is to map and determine graduated hot or safe zones using different criteria. Accident criteria (AC): AC1 is the number of mortalities criterion, AC2 is the number of injured people criterion, AC3 is the number of accidents with damage only criterion and AC4 is the total number of accidents criterion.

Key words: Spatial analyst, kernel density estimation, GIS, density map, traffic accidents.
