I have a super streets taxi scene I've been thinking of automating. It's a single lane dog bone using two super street "Y" for the reversing loops. The roadbed is in place, so I'm not looking to modify the roadbed configuration. One reversing loop is around Grand Central Terminal (GCT) and the other around Columbus Circle. The lane runs through the city. I'd like to cue taxi's around GCT. I'm thinking a taxi stops in the rear of GCT, a taxi in front of GCT then moves out, and the taxi in the rear advances to the front after which the scene repeats.
Mechanism would be roadbed embedded optical sensors to detect position, roadbed blocking, relay control logic and a solenoid to reset the "Y".
Any suggestions to improve the automated scene or mechanization would be appreciated. Thanks in advance.
