Link travel times

What is missing is the value of outLinkTravelTime. When no other information is available, then we use

$$\hbox{linkTravelTime} = \hbox{linkLength}/\hbox{linkFreeSpeed} \ .$$

For the CA traffic simulation, the free speed is one cell per time step, or 7.5 m/s.

Congestion will reduce the speeds on the links. This effect is included into the router in Chap. 12.
