Routing

Notes
|
Traffic permitting, drivers can get on and off freeways where and when they please. In the current design (modeled under CSIM), a CAV on a CAVWAY announces a fixed destination. Knowing the destinations of all CAVs on the CAVWAY allows the CAVWAY Control (CC) to measure loading, control access, and prevent congestion, and to monitor and modify CAV protocols accordingly.
Two types of routing Fixed routing is what we now expect from buses, which depart from and arrive at stations according to a schedule. A passenger at a CAVWAY station (node) might join a queue to board the next available bus. A reservation might improve his position in the queue. Variable routing would apply to private (dual-mode) CAVs and to commercial on-demand CAVs, such as taxis, shuttles, limos, and other ride-share vehicles. The rider of a taxi or limo might pay a predefined price calculated by the CAV or TaaS company, presumably based on trip length, CAVWAY-use fee, prevailing traffic, and conditions of the trip (private or shared vehicle). Travelers in private CAVs would pay CAVWAY-use fees and, like taxis or limos, might need CAVWAY reservations depending on traffic conditions. |
There might be changes to a CAV destination, but changes would be the exception. We understand that a driver normally enters a freeway with a destination in mind, but the difference is that, since the driver does not need to coordinate with other drivers - except to signal and maintain safe separations - changes to his plan generally go unnoticed by outside observers.
Routing is also discussed under CSIM. |
