An Improved Logit Model for Passenger Flow Sharing Rate of Regional Comprehensive Transport Channel

With the development of various modes of transportation, the competition of various modes of transportation in the transportation channels has become the norm in this era. In this paper, the weather influence index is added to the traditional logit function composed of economy, speed, convenience, comfort and safety factors, and an improved logit function model is constructed to analyze the passenger flow sharing rate. Taking the Beijing-Harbin Channel as an example, the passenger flow sharing rate of the four transportation modes from Harbin to Beijing, high-speed railway（HSR）, railway, aviation and highway is calculated. At the same time, the sensitivity analysis of speed and fare factors is also carried out, and relevant suggestions are put forward to optimize the traffic system of Beijing-Harbin channel.
