One of the world’s leading ITS consultants has published the definitive history of the traffic signal.

Alistair Gollop’s book “Traffic Signals: An introduction to signalised junctions and crossing facilities in the UK”, charts the history of the technology from their first introduction worldwide, at Bridge Street, Westminster in 1868.

He explains how traffic signals have subsequently developed alongside the rapid growth of motorised traffic, to attain a complexity unimaginable to the early pioneers in the signal field.

It explains a series of terms and the differences between them, including MAN, VA, FXT, CLF, UTC, SCOOT and MOVA.

In addition to the history of pioneering signal development, Traffic Signals looks at the way in which modern signals operate and the equipment commonly used in current traffic control systems in the UK.  It also looks at how signalised junctions and crossings are designed, explaining the fundamental design principles, and how these are used by modern software modelling tools to predict traffic operation.

Included within Traffic Signals is a handy set of Standard Detail drawings which are commonly used when specifying and designing projects.

Alistair Gollop wrote an article in a previous Smart Highways which provided the foundation to the early part of the book.  The whole book is available on Amazon.

The InSync traffic management solution offered by Rhythm Engineering in the USA appears to be far superior to systems such as SCOOT in the UK – see What is stopping us from deploying solutions such as InSync across the UK?
