and longer with its increasing demand. The equilibrium between different modes will be
achieved ultimately, and the shares and the total travel time of the whole network will not be
changed at such equilibrium.
Assuming that the total number of travelers between O-D remains unchanged take
the value of 10000 persons each hour, Figures 8a and 8b, respectively, show the change
trends of the shares and the total travel time with the proportion of class I which is sensitive
to the travel time. It can be shown that the share of bike mode will decrease and the share
of car will go up slightly, while the share of bus remained unchanged. Meanwhile, the total
travel time of whole network will increase with the increment of the proportion of class I.
The results also imply that in the multiclass multimodal transportation network, the more
travelers who focus on the factor of travel time, the lower the total travel time of network is.
