Transit-oriented development form on traffic assignment, transit and land-use features

Transit-oriented development (TOD) is one of the most beneficial strategies that addresses both urban and transportation issues in solving urban traffic problems. To achieve more sustainable transport and resolve urban sprawl problems, this paper establishes a TOD evaluation criterion and formulates a novel TOD site-selection method, which fulfills the principle of sustainable transportation for the city of Qazvin. This paper outlines plausible TOD locations through three complementary steps: first, the saturated links of network are investigated by traffic assignment which were 12 zones; second, the cross points of high demand for public transport stations and top saturated links are considered and third, the three essential criteria of density, diversity and distance (3Ds) are calculated for each of the selected stations to rank them by the analytical hierarchy process method. The results show that the three top-ranked TOD locations with the highest potential are nominated for TOD implementation among the 43 candidates.
