Interactions between driver information, route choice, and optimal signal timing on a simple network

摘要: The interaction between driver information, route choice, and optimal traffic signal settings was investigated using a simple two-route system with single "T" intersection fixed O-D demand. logit model the method of successive averages (MSA) were used to calculate choice probabilities stochastic equilibrium assignment. Given an assignment, which minimized average delay calculated; flow reassignment new then obtained this iterative process continued until convergence. calculations performed either directly in combined assignment/signal optimization or stages output flows assignment as inputs TRANSYT-7F iterating two models. Results show that unique joint timing/assignment is reached all cases provided certain precision drivers' perception not reached. If information increases beyond, results clearly no longer exists. In fact, three points exist after bifurcation point. Two these are stable one not.
