A DMB-TCA Simulation Method for On-Road Traffic Travel Demand Impact Analysis

Travel Demands influence micro-level traffic behavior,
furthermore traffic states. In order to evaluate the effect of travel
demands on traffic states, this paper introduces the Demand-
Motivation-Behaviors (DMB) micro traffic behavior analysis model
which denotes that vehicles behaviors are determines by motivations
that relies on traffic demands from the perspective of behavior
science. For vehicles, there are two kinds of travel demands: reaching
travel destinations from orientations and meeting expectations of
travel speed. To satisfy travel demands, the micro traffic behaviors are
delivered such as car following behavior, optional and mandatory lane
changing behaviors. Especially, mandatory lane changing behaviors
depending on travel demands take strong impact on traffic states.
In this paper, we define the DMB-based cellular automate traffic
simulation model to evaluate the effect of travel demands on traffic
states under the different δ values that reflect the ratio of mandatory
lane-change vehicles.
