Resumen
Decision makers need appropriate information systems to carry out spatial analyses related to transportation. Hence, Geographical Information Systems (GIS) are one of the effective tools used for realizing spatial analyses. Therefore, GIS were also used in this study for evaluating the information about intercity bus travels in Turkey. For this purpose, the intercity bus travel matrix obtained is transferred to GIS environment in order to evaluate this matrix in a visual environment. Estimation of Origin-Destination (O-D) matrices is very important in transportation planning, and several methods are used to obtain them. However, since it is generally expensive and time-consuming to use classical methods based on home surveys or roadside interviews, other methods have been developed. The model developed by Bell is also one of them, and estimates travel matrices from traffic counts. For finding the daily intercity bus travel matrix for the year of 2015 in Turkey, this model was used.
