Joint Analysis of the Commuting Departure Time and Travel Mode Choice: Role of the Built Environment

الملخص EN

This paper aims to conduct an empirical study to evaluate the influence of built environment features and socioeconomic factors on commuters’ simultaneous choice of departure time and travel mode.

Using Kunming, China, as the study region, the 2015 Regional Household Travel Survey and 2016 Point of Interest data are used in the analysis.

The results show that, in addition to socioeconomic factors, built environment, such as the density of residential building, employment, and service facility are correlated with joint choice behavior.

Moreover, there exist differences regarding the influence of built environment and socioeconomic factors on departure time and travel mode choice.

The dissimilarity parameters show that commuters prefer to shift travel mode than departure time generally when travel condition alters.

In order to examine the policy measures’ potential performance, the paper conducts simulation tests based on the Monte Carlo method.

The simulation results show that congestion pricing of car travel during peak hours can reduce the number of commuting trips, and reducing travel time of public transit would be a better strategy to attract more passengers during peak hours.

Moreover, reasonable land use planning, such as building more bus stops around commuters’ home location, would be a long term and fundamental approach to reduce mobile-source emissions and attract more public transit passengers.
