Validating the results of a route choice simulator

Finally, both the scenarios of link capacity degradation and random link capacity are used to illustrate the model’s applications.

However, it is not reasonable to adjust traffic flow continuously due to travelers’ activities constraints.Some researchers use deterministic models or stochastic models to study the day-to-day flow evolution. proposed three dynamic systems by the deterministic traffic assignment processes [3, 4].The flow evolution trajectory can be provided explicitly in deterministic models.It is hard for them to make the best choice every time due to their bounded rationality and the uncertainty of environment. If the travel time of a path was short in the past days, its probability to be chosen is big in the current day. These characteristics are similar with the features of the reinforcement learning (RL) theory.Under RL, if an action yielded a high payoff in the past days, the probability assigned to it increases in the current round, or the behavior associated with the action gets reinforced [23].

    Aug 28, 2014. In this paper, we propose a day-to-day route choice model based on reinforcement learning and multiagent simulation. Travelers' memory, learning rate, and experience cognition are taken into account. Then the model is verified and analyzed. Results show that the network flow can converge to user.…

    Subject drivers are invited to make journeys between specified origins and destinations under a range of travel scenarios, during which the simulator automatically records their route choices. This paper describes validation experiments carried out during the period Summer 1994 to Autumn 1995 and reports on the results.…
