Abstract
Highways constitute one of the busiest and most vital linear elements in a country's transportation system, and their significance has grown steadily with the expansion of urban life. Consequently, access to up-to-date and efficient information about these linear elements plays a crucial role in managing the transportation systems of nations. Volunteered Geographic Information (VGI) is generated by users who contribute their experiential or local knowledge of a specific location to a spatial database. Statistical approaches help in understanding the trends of participatory behaviors. This study examines the patterns of contributors' involvement in mapping highways and roads in the OpenStreetMap (OSM) database in Tehran. Analyzing participatory patterns provides rich information on biases, statistics, and user activity directions and shifts, which are instrumental in transportation, urban planning, and management. The proposed approach evaluates how the characteristics of a road impact its classification. Highway classes are categorized using a random forest classifier, and the inferred mapping trends are analyzed based on the classification. Linear data from Tehran city will be used for the upcoming experiment, and the classification algorithm will be applied with the extraction parameters that resulted in the highest classification accuracy. Results demonstrate that the optimal combination of extraction parameters, such as the azimuth of highways, geodesic length of lines, distance from the first mapped point to the nearest street, and the kernel density of the initial points, achieves an F-Score of 71%. An examination of the semantic parameters, such as the highway name and user name, indicates their ineffectiveness on classification accuracy. After assessing the importance of each selected parameter, the azimuth parameter is identified as the most influential factor in the classification of highway types regarding user participation behavior.
