Abstract:

The traffic system with two lane mainroad and one lane on-ramp was simulated and analyzed by using the modified weighted probabilistic cellular automaton model.The conformity effect of the vehicles on the ramp was considered.The phase diagrams with and without the conformity effect were analyzed and compared to study the influence of conformity effect on traffic flow characteristics.The variations of the capacity at upstream the on-ramp,the on-ramp and down-stream the on-ramp with respect to the conformity probability were analyzed,when main road and on-ramp both are saturated.The results indicate that conformity effect can weaken the bottle necks effect caused by the main road on the on-ramp to some extentand increase capacity of on-ramp.

Key words: engineering of communication and transportation, on-ramp system, cellular automaton, conformity effect
