Abstract: Transportation equity is vital for the fulfillment of citizens’ activities. To make better decisions for transportation planning, it is appropriate to have a method to evaluate each mode and assign an equity score to it. This paper aims to propose a method to assess the level of equity using different transportation modes in each zone of a city. Here, the equity level takes into account on one side the proportion between the frequency of long and short-distance trips, the volume-to-capacity ratio of streets, the air quality, and the parking availability. On the other side, the ratio of costs associated with using passenger cars, the average income of the residents, and transit and cycling infrastructure quality is used in a zone of a city. In this regard, at first, indicators are considered to assess the condition of buses, cycling, and passenger cars. Then, the Fuzzy Inference System (FIS) is used to determine the level of equity for each mode. The method has been applied to regular buses, cycling, and passenger cars in Kerman, Iran, as a case study. The results indicate a significant difference between the equity levels perceived by citizens and the performed calculations. The citizens’ perceptions about the equity of regular buses and cycling seem to be more pessimistic than what the FIS model shows. Based on the model outputs, more restrictions must be established about using passenger cars in most of the zones. Nevertheless, in this regard, citizens have stated that the current situation is fair. We believe this method can be a helpful way to quantitatively assess the equity level of transportation systems in each zone.
