Evaluation of Urban Green Transportation Development Level Based on Traveler Perception——Taking Hohhot as an Example

China’s continuous progress toward the strategic goal of a strong transportation nation has made green transportation one of the key development directions. Therefore, it is necessary to research the level of green transportation development within the city. This paper constructs an urban green transportation evaluation system from four dimensions, transportation function level, environmental protection and energy, information and policy, and social impact. Meanwhile, the green transportation evaluation classification index is proposed based on the perspective of traveler perception combined with the national policy on green transportation. Combinational optimization was conducted with the reference point in the prospect theory and the comprehensive evaluation value of each index was calculated based on the information assembly in group decision-making. Then, rationalization analysis was put forward. Taking the city of Hohhot as an example, the results show that Hohhot has achieved remarkable results in public transportation, environmental protection, and new energy promotion in the green transportation system. It is suggested that the municipal government should pay more attention to the green transportation policy, transportation information, transportation law enforcement, transportation inclusiveness, and slow-moving transportation.
