Phase diagram of a single lane roundabout

Simulation study of interference of crossings pedestrian and vehicle traffic at a single lane roundabout

“…However, Fig. 2(b) presents 11 the variation of vehicle flux, as the rates α 1 and P cr change, three phases can be observed: the free flow (F); where the flux 12 increases with the rates α 1 , the congested (C); the flux becomes saturated, and the gridlock (GL); here the flux becomes null. In order to get better insights into the traffic dynamics with the presence of pedestrians on those phases, we plotted the 1 distributions of vehicles in space-time of the circulating lane, entry and exit lanes (Fig.…”

“…Many 3 observed traffic phenomenon have been successfully described by computer simulation with various models, e.g. car 4 following, Fluid-dynamical method, and Cellular automaton (CA) [1][2][3][4][5][6][7][8][9][10][11][12][13]. This later has been adopted extremely and well 5 received as a good tool to study the traffic and/or pedestrian dynamics [8][9][10][11][12]14].…”

“…This means that arriving 11 pedestrians will follow the crossings ones (i.e. herd crossing behavior) to cross, which increases the delay for vehicles and 12 consequently the interactions between vehicles before the crosswalk. This is why the Congested-Free phase enlarges.…”

Cellular Automaton to Study the Impact of Changes in Traffic Rules in a Roundabout: A Preliminary Approach

“…The topics studied have included study road traffic dynamics in roundabouts [69], and the study of probability of road accidents [70,71]. The current publication focuses on developing a model for multi-lane roundabouts.…”

An extended car-following model accounting for the honk effect and numerical tests

“…This increasing interest is stimulated not only by its practical application for optimizing traffic facilities and management, but also by the observed many interesting nonequilibrium phenomena, such as phase transition, hysteresis effect and stop-andgo waves in traffic flow [4][5][6][7][8].…”
