The UK’s Transport Research Laboratory (TRL) has announced that it has sent Version 7 of its MOVA (Microprocessor Optimized Vehicle Actuation) software to traffic signal companies, which are now integrating it into their controllers and product portfolio for onward shipment to customers in late summer. MOVA is for the control of traffic light signals at isolated junctions that are uncoordinated with any neighboring signals. With nearly 4,000 junctions now under MOVA control, TRL has added Motus Traffic Limited to the MOVA Development Group, which consists of traffic signal companies Siemens, Peek, and Telent. As a result, Motus will now develop MOVA units to be supplied with its TM150 Traffic Signal Controllers, which have recently been granted approval by the Secretary of State as being TR2500 compliant, and as a standalone unit to be integrated on existing sites with third-party manufacturers’ traffic signal controllers.
MOVA’s new features are: Traffic Management Act (TMA) logs, which have been designed to help network managers observe and review junction operation, enabling problems to be identified more easily and allowing analysis of improvements to be made; an extension of the measurement of saturation flow feature, which now has a statistical analysis carried out on the data and there is the option to feed statistically robust values back to the working configuration data; and changes to the messages, which improve the layout and provide fuller information to the way CANDET (the bus priority cancel detector) behaves.
TRL has also announced that together with Siemens and Peek Traffic it has launched SCOOT (Split Cycle Offset Optimization Technique) MMX, the latest version of the SCOOT kernel and updates to the Siemens and Peek Traffic UTC. The SCOOT Urban Traffic Control system is now operating in over 250 cities and towns worldwide and recent releases have incorporated many new features aimed at providing priority to public transport and, in the last release (MC3), new strategies to benefit pedestrians at crossings. In the new MMX version, the multimodal theme is continued with additional facilities to prioritize pedestrians at junctions, as well as features to improve operation during low flow periods. Specific areas of functionality development include: pedestrian variable invitation to cross; cycle time sub-region independence; and reduced cycle time at quiet periods.
Both new products are being launched at Traffex 2011, at the NEC Birmingham, UK, March 29-31.
