Hi again, just a quickie
Are all these despatch systems like.....erm
send a job to a specific driver
can a job be displayed to all cars and the first to accept gets it?
All systems basically work the same but the "fastest finger" method went out with the Ark.
Essentially, the town is broken down into areas and these are then treated like large taxi ranks.
Jobs go out automatically to the top car in the area providing the vehicle is suitable.
If there is no car, the system usually looks in the immediate surrounding areas to find one.
(This may be the nearest or the one that's been waiting the longest depending on how the system is set up to work.)
If it still can't find a car, then it broadcasts to all cars allowing the drivers to bid for the job.
After about 15 seconds, it again makes a decision based on a similar set of rules.
Hope this helps.
Bill
