Has anyone investigated delays associated with the operation of isolated ped crossings Outside my old Plymouth office there is a newly installed puffin serving relatively few peds, say 1 per minute. Invariably, the practical operation goes something like this. 1) Confronted with a constant flow of slow moving traffic, ped presses button 2) traffic continues to roll 3) peds get very impatient 4) ped sees gap in traffic 5) ped crosses road 6) sensors detect gap in traffic. 7) signals turn red 8) traffic stopped at empty crossing OK this particular crossing is particularly badly programmed, but I know of similar sites which please neither peds nor drivers. Accepting that there are UTC issues, I wonder if stopping traffic on ped demand would not result in a net reduction in overall delay. I have not done my sums but leaving aside pedestrian delay, it seems a choice between delaying a few free flowing vehicles or more slow moving ones, which soon make up the lost ground. Anyone done any work on this. Graham Jones Traffic Analyst - Somerset County Council Tel 01823 358235 This communication is intended solely for the person (s) or organisation to whom it is addressed.
