Optimal model of taxi waiting time fee under traffic congestion condition

Based on economics demand theory, taxi income was divided into starting fee, mileage fee and waiting time fee.Taxi capacity was taken as constraint condition, the influence factors of taxi income during peak period and non-peak period were considered, the influence levels of waiting time fee on taxi demand and income were analyzed, and the optimal model of taxi waiting time fee under traffic congestion condition was set up.Based on the actual situation of taxi market in Beijing City, the example verification was carried out by using three schemes including original scheme, adjustment scheme and proposed scheme.Analysis result shows that when the starting fees are 12, 14, 12 yuan, unit mileage fees are 2.0, 2.3, 2.0 yuan·km-1 and waiting time fees are 24.0, 55.2, 55.2 yuan·h^-1, taxi incomes are 669.9, 504.9, 675.9 yuan respectively. Under adjustment scheme, taxi demand decreases by 46.1%, and taxi income decreases by 25%. Under the proposed scheme, taxi demand decreases by 18.5%, and taxi income keeps stable level compared with original scheme.According to the exist structure of taxi fee, the adjustment objective of taxi demand and income can be realized by using proposed scheme.In the reformscheme of taxi price in Beijing City, it is suitable to keep or decrease starting fee and mileage fee and increase waiting time fee.
