![]() This is because vehicles need at least one cell between them to move. no intersections, grid-size-x = 0), the maximum possible flux is $J=0.5$, at a density $rho=0.5$. In the rule 184 model of highway traffic (i.e. The Flux plot shows the velocity multiplied by the density. if v=1, no vehicle stops, and if v=0, all vehicles are stopped. The Velocity plot shows the percentage of vehicles moving, i.e. The following parameters affect the self-organizing method. To avoid stopping of vehicels, set this equal to half the length of the street or equal to a factor of half the length of the street. The next parameter affects the marching or green wave methods Choose between following methods: “Marching”: all lights march in step, either vertical or horizontal “Green-wave”: Lights are synchronized so that vehicels flowing eastbound or southbound would not need to stop (at a flow speed of 1) “single Moebius”: whole city is a single self-intersecting street… Thus, GRID-SIZE-X should be equal to GRID-SIZE-Y. Choose boundary conditions: “cyclic”: periodic boundaries “simple Moebius”: horizontal roads continue as vertical roads and vice versa, i.e. %VERTICAL Determines probabilistically the percentage of cars on vertical streets (complementary to horizontal ones) ![]() Determines probabilistically how many cells are occupied by vehicles. If false, only south and eastboud.ĭENSITY. no intersectionsįOUR-DIRS? If true, streets flow in four directions (alternating). Use GRID-SIZE-X=0 for freeway model (Rule 184), i.e. GRID-SIZE-X and GRID-SIZE-Y determine how many streets will be with each orientation (vertical and horizontal). The controls above these buttons should be set before “Setup”, the others can be changed anytime.
