Models and simulations of on-ramp system considering conformity effect

The traffic system with two-lane main road 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 downstream 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 bottlenecks effect caused by the main road on the on-ramp to some extent and increase capacity of on-ramp.
