Urban Traffic Control

Steve Lane, Commercial Director at Triteq, talks about the successful deployment of ZigBee in Barcelona where a low-cost wireless metropolitan network for location and citizen services was established. The project, he says, demonstrates ZigBee's effectiveness as an urban communications system solution ZigBee is based on the IEEE radio frequency standard 802.15.4 - 2006 for Wireless Personal Area Networks (WPAN), which provides a license-free radio frequency for a flexible, robust private wireless network.

Prof. Klaus Banse, President of ITS Colombia and Ing. Robert Miranda, Head of the Traffic Management and Control System of Cartagena de Indias, Columbia, outline early cost benefits of an adaptive traffic control system. At the beginning of this year, Cartagena de Indias, located on the north coast of Colombia in the Caribbean, implemented a new adaptive traffic control system on 52 intersections with an investment of US$4.5 million.

The Industrial Automation Group of Advantech has introduced two new signal conditioning modules, the ADAM-3112 and ADAM-3114. The 3112 is an isolated AC voltage to DC voltage module while the 3114 is an isolated AC current to DC voltage module. Both devices can convert up to 400V AC or 5A AC signals to 0~5V DC signals for data acquisition cards to measure while reducing the harmful effects of ground loops, field noise and electrical interference.These modules are suitable for DIN rail mounting, designed for

Peek Traffic has launched two brand-new traffic controllers, the ATC-1000 and ATC-2000, both of which have been designed from the ground up to be the definitive solution when it comes to advanced features, standards compliance, ease of integration and intelligent ergonomics. The ATC-1000 and ATC-2000 use NTCIP communications natively and are entirely compatible with Peek's IQ Central traffic management system, as well as many other traffic management systems. According to the company, the controllers have b

Michael Noblett of Connexis discusses international progress towards common standards for cooperative road infrastructures. Will vehicle safety communications standards be able to support ITS on the international level, or will we settle once again for regional interoperability only? The answer lies in the current status of the draft standards themselves, and the requirements users and authorities are placing on the people who draft them.

Navtech Radar's millimetric-wave systems are being researched on the M42 in England to look into how this type of detector can assist in the opening of the hard shoulder as an additional running lane. Here, the company's Stephen Clark talks about the technology being used. In England, the Highways Agency's (the HA, an executive agency of the Department for Transport) Managed Motorways system - formerly called Active Traffic Management - uses electronic signs and signals mounted on gantries to direct drivers
