System to monitor vehicles at notorious junction

AN INNOVATIVE traffic device will be installed at Hipperholme crossroads to see if it will help ease congestion and increase the safety for road users.

Calderdale Council’s Highways department are set to monitor the current traffic flow and volume at the notorious junction at the Whitehall Pub and Christ Church at Hipperholme before installing the MOVA (Microprocessor Optimised Vehicle Actuation) system.

MOVA is designed for the full range of traffic conditions, from very low to a junction that is overloaded.

Councillor David Kirton (Con, Hipperholme and Lightcliffe) said at their ward forum that results before and after using the system at peak times will be analysed by Calderdale’s traffic department.

“The MOVA scheme will bring better information about traffic levels and problems at the crossroads,” he said. “The pressure pads will be installed in late spring or early summer to monitor traffic through the junction.”

Before congestion occurs, MOVA operates in a delay minimising mode. So if any approach becomes overloaded, the system switches allowing the built up traffic to go through first. MOVA is also able to operate at a wide range of junctions, from the very simple ‘shuttle-working’, to large, multi-phase multi-lane sites.

Originally designed by Transport Research Laboratory during the 1980s, it is now a very well established strategy for the control of traffic light signals at isolated junctions that are uncoordinated with any neighbouring signals. It can also be used at stand-alone pedestrian crossing.

Currently the UK is thought to have at least 3000 sites equipped with MOVA with each year seeing at least another 200 installations.

According to the TRL, the scheme is particularly suited to sites with high traffic flow, and ones experiencing capacity difficulties under Vehicle Actuation control with congestion on one or more approaches. It is being used by almost all authorities who have responsibility for traffic signals, and is a requirement on new signal installations and major refurbishments on trunk roads.
