概要:
抄録:
Effects of a bottleneck in a linear traffic way is investigatedusing a simple cellular automaton model. Introducing a blockage sitewhich transmit cars at some transmission probability into the rule-184cellular automaton, we observe three different phases with increasingcar concentration: Besides the free phase and the jam phase, whichexist already in the pure rule-184 model, the mixed phase of these twoappears at intermediate concentration with well-defined phaseboundaries. This mixed phase, where cars pile up behind the blockageto form a jam region, is characterized by a constant flow. In thethermodynamics limit, we obtain the exact expressions for severalcharacteristic quantities in terms of the car density and thetransmission rate. These quantities depend strongly on the systemsize at the phase boundaries; We analyze these finite size effectsbased on the finite-size scaling.
