Modeling travel mode choice in response to the cordon pricing of city's central zone and improving transportation with multiple logit models in different trip purpose (Case study of Esfahan)

The need to reduce the use of cars and the use of public transport should be the main goal of transport management policies. One of these policies is to determine the city's central zone and receive a toll from passengers arriving at this zone. Two different methods including stated preference and revealed preference are used. In this research, the aim is to create the possibility of modeling the pricing policy of the city's central zone and to study the results before the implementation and review the effect of improving the public transportation system on it. The stated preference method is used to examine the effect of the pricing policy of entering the zone in terms of improving the public transportation system. In this regard, modeling has been done with discrete multi-choice logic models for more precisely modeling, this modeling is done by business trips and shopping trips. To do this research, data collection was carried out through personal interviews with personal vehicle users for the purpose of travel trips and shopping trips, respectively. Interviewees (182 different drivers) interviewed by questions about travel characteristics, socio-economic features and their options in terms of pricing policies for personal vehicle access. The values of variable coefficients for entering the PRICE zone in the Utility Function of Multiple Logit models are equal to -0.00033 and -0.00032 for business and hopping trips respectively, and their elasticity are -0.6394 and -0.6350, indicating that the increase of price has the greatest effect on business trips.
