Interpretation and writing of TOPAS 2500 Controller Specification forms for Transport Modellers and Design Engineers
This course is a detailed examination of Controller Specification forms to allow Transport Modellers to extract accurate information for modelling and assist Traffic Signal Design Engineers in preparing Traffic Signal Controller Specifications. It is based on the TOPAS 2500 Specification (formerly TR 2500/TR2210A/MCE0141) for microprocessor traffic controllers. Using a real world example the course takes delegates through an ITS1827D document considering all the elements which make up a Specification with theory breaks covering Phase Delays, Detection, Controller Logic, UTC, VA, CLF, Call Cancel Loops, Shuttle Working, SDE/SA, Hurry Calls, Priority/Emergency Modes, Pedestrian Linking and Cross Stream Linking.
Who should attend.
This course will benefit both Transport Modellers and Traffic Signal Design Engineers
Prerequisites.
Prior to attending the course, Delegates should have a basic understanding of traffic signal terminology such as Phases, Stages and Intergreens.
