This study examines path flows for road networks by considering various cost factors and finding the route with the minimum cumulative cost. The research explores how different cost factors contribute to explaining observed link traffic flows. The results suggest that flows from various path types associated with different internal cost components, along with distance, provide the best fit for traffic flows in the Minneapolis - St. Paul metropolitan area.
This study examines path flows for road networks. Path flows sum individual route choices from individual travelers, associated with specific path objective. We estimate these flows for each cost factor of auto travel: time, safety, emission, and monetary costs, as well as their composite, internal and full cost of travel. For each factor, we find the route with the minimum cumulative cost. We further explore the extent to which each cost factor contributes to explaining the observed link traffic flows given an estimated home-to-work demand pattern. The results of the Minneapolis - St. Paul metropolitan area indicate that flows from multiple path types, associated with different internal cost components, along with distance, provide the best fit.
