On-Ramp Control

  • D. Huang
Conference paper

Abstract

We study the phase transition on a highway induced by the fluctuations of on-ramp flow. The highway traffic is provided by a hydrodynamical model. We analyze the characteristics of perturbations to induce congestion near an on-ramp. The phase boundary is obtained. A scaling relation is revealed. We also analyze the time evolution of the local density profile. Conventional control mechanisms to regulate the on-ramp flow are examined. A new control scheme is proposed to suppress the congestion.

    The following parameters are adopted[15,16]: r = 0.5 min, co = 54 km/hr, p = 600 veh km/hr, V(p) = Vo (1 — p/po)/[1 + 100 (p/po)4], 0(x) = exp [—x2/(2Q2)] /(2Tr v),where Vo = 120 km/hr and po = 140 veh/km are the maximum values for velocity and density, respectively, and v = 60 m denotes the length of the on-ramp.Google Scholar
