Three-phase traffic theory and highway capacity

Three-Phase Traffic Theory and Highway Capacity

Hypotheses and some results of the three-phase traffic theory by the author are compared with results of the fundamental diagram approach to traffic flow theory. A critical discussion of model results about congested pattern features which have been derived within the fundamental diagram approach to traffic flow theory and modelling is made. The empirical basis of the three-phase traffic theory...

Optimization Model of the Highway Toll Plaza Traffic Capacity

The traffic capacity of the highway toll plaza is studied in this paper. This model is based on M/M/c and M/G/K queuing system. The process of the vehicles pass through the toll plaza can be divided into two parts: entering system and departing system. Considering the reality that the highway traffic flow increases year by year, two models are proposed in this paper: (a) Find out the optimal nu...

Causes and Effects of Phase Transitions in Highway Traffic

Possible explanations of phase transitions in highway traffic

It is shown that all the phase transitions in and out of freely flowing traffic reported earlier for a German site could be caused by bottlenecks, as are all the transitions observed at two other sites examined here. The evidence suggests that bottlenecks cause these transitions in a predictable way, and does not suggest that stoppages (jams) appear spontaneously in free flow traffic for no app...

Memoirs on Highway Traffic Flow Theory in the 1950s

T has been a revival of interest in traffic flow theory in the late 1990s, mostly because vehicle detectors have been installed at many highway locations throughout the world to record the passing of vehicles. The purpose of these detectors is to monitor congestion and provide information for possible control or to advise motorists of possible alternative routing. To understand the consequences...
