Choice of the control variables of an isolated intersection by graph colouring
Choice of the control variables of an isolated intersection by graph colouring
This paper deals with the problem of grouping traffic streams into signal groups on a signalized intersection. Determination of the complete sets of signal groups, i.e. the groups of traffic streams on one intersection, controlled by one control variable is defined in this paper as a graph-coloring problem. The complete sets of signal groups are obtained by coloring the complement of the graph of identical indications.
