TOPAS 2500 Controller Specifications

London - venue tba  16.05.2019

Who should attend.

This course is intended to provide delegates with an appreciation and understanding of the TOPAS specification TR2500 (formerly TR2210A/MCE0141) for microprocessor traffic controllers. Delegates will be given an introduction to the specification followed by an in depth examination of the appendices including a brief revision of related topics such as VA, CLF, UTC and MOVA. Delegates will also be introduced to Controller Change Logic (Boolean) and through a series of tutored workshops will prepare logic change diagrams and complete a controller specification using the MCH1827d spreadsheet. The course will benefit those involved in the detailed specification of traffic controllers and those wishing to know more about the current specification and the facilities available.


Prior to attending the course, Delegates should have a good understanding of traffic signal terminology and practice.
