Abstract: It is well known that noise reduces the efficiency in transportation. However, what is not so well known is that a small variation of noise can sometimes trigger an abrupt change to the whole system. In this paper, we report such a phase transition induced by the variation of noise. We study the influence of stochastic noise in asymmetric simple exclusion processes in the presence of an on-ramp. Two types of bottleneck can be induced by the noise. With a small noise, a light bottleneck is observed as traffic jams emerge intermittently around the on-ramp. With a large noise, a heavy bottleneck is observed as the traffic in the upstream becomes severely congested. An abrupt transition separates these two types of bottleneck effects. We obtain the detailed phase diagram, which summarizes all the possible states. The density profile, headway distribution, and spatial-temporal trajectory are discussed. We also comment on the daily experiences on highway traffic.
