The company used the exhibition to present Sitraffi c sX – its new controllers for traffi c lights and detectors.
The technology allows operators to extend the functions of controllers already deployed in the fi eld by means of remote updates. There is no longer any need to interrupt ongoing operations. This is made possible by an additional real-time processor that can take over control of a set of traffi c lights if required. Dangerous “lights out” situations are prevented and the dangerous traffi c conditions minimised. Remote maintenance can also be carried out without shutting down the system.
The new Sitraffi c sX generation of controllers is internationally compatible and can be extended by adding new modules. It can also be deployed as a stand-alone device with a virtual traffi c

management solution or for optimised and coordinated traffi c control systems.
Dr Thomas Sachse, traffi c engineering expert system design and engineering, believes there has been a change in thinking in the UK. He said: “Some years ago the philosophy was to inform drivers. Now it has changed and we’re using active traffi c control. This is extended in the UK and even in the US because they have set up big programmes to extend their motorways in the direction of active traffi c control. I think it is a world wide process and there is a re-thinking and changing of the philosophy from information to real control.”
Sitraffi c sX is part of a web-based, scalable Sitraffi c family with which even smaller towns can realise effi cient traffi c control.
On the radar
British traffi c and vehicle monitoring solutions company Applied Traffi c launched its latest traffi c data collection system, the Bat-Box, at this year’s exhibition.
The Bat-Box is an inconspicuous device, which is easy to install and can be attached to existing street furniture. The radar detects and records the passage of motor vehicles and/or bicycles over a range of scenarios that include multi-lane highways, bi-directional traffi c lanes, paths, lanes and cycle tracks.
It is equipped with an integrated GSM/GPRS modem for streaming data, such as direction, lane, speed and length, to a back offi ce computer, server or cloud based data storage system. Up to 600,000 individual vehicle records can be stored at one time.
Alan Cook, managing director of Applied Traffi c, said: “The Bat-Box is an exciting and innovative new product designed for a range of traffi c monitoring applications and as an alternative to inductive loop based systems.
“We had more enquiries for the radar during the fi rst day of Intertraffi c than we’ve had at the last few shows put together.”
Navtech Radar, a manufacturer of radar-based automatic incident detection (AID) systems, showcased its CTS350-X radar at Intertraffi c.
It provides a way of automatically detecting incidents, including stopped vehicles, people and debris on strategic roads, bridges and in tunnels. It uses high frequency radar to scan the whole road surface, both up and down stream. The radar detects and then tracking software will follow both moving and stationary objects. The system is rapid, reliable, cost effective, low maintenance and has a low false alarm rate.
Director Dr Stephen Clark is excited about the market for intelligent transport systems in the UK.
He told Highways Magazine: “It’s an exciting market for us. We’re doing a bit of work with Transport for London (TfL) and have also worked with the Highways Agency who are open to trialling new technology.”
