I would be interested to know if any authorities have any operational experience with Peek PRISM. Our ambulance station is locating to a new site the access road they are located on is signal controlled and they will require a hurry call facility at the junction when leaving their station. They are located 500m from the junction and the junction is fitted with an OMCU. To avoid 2 new BT lines and Tele12's Peek have suggested the use of PRISM. Have any local authorities used this form of priority control for similar applications Thanks Richard Backhouse Principal Engineer Southend Borough Council ----------------------------------------------------------- A message from the TCUG mailing list.
