Abstract

In this chapter, the constraints for dynamic traffic necessary for a urban transportation network are presented. These constraints include flow conservation for links and nodes, flow propagation, first-in-first-out (FIFO) and oversaturation. Associated with these constraints and different needs for dynamic travel time information, two definitions of travel time are considered.
