Green light for traffic signal performance

A revamp of traffic light maintenance is helping to reduce congestion, save money and improve safety on Greater Manchester’s roads, according to the latest figures from Transport for Greater Manchester (TfGM), which is responsible for all 2,400 traffic signals across the region. These show that the number of incidents of traffic signal failure has steadily declined over the past three years. Between July 2015 and April 2016, there was an average of 413 signal fault faults per month. This is 24 per cent

A revamp of traffic light maintenance is helping to reduce congestion, save money and improve safety on Greater Manchester’s roads, according to the latest figures from 817 Transport for Greater Manchester (TfGM), which is responsible for all 2,400 traffic signals across the region.

These show that the number of incidents of traffic signal failure has steadily declined over the past three years. Between July 2015 and April 2016, there was an average of 413 signal fault faults per month. This is 24 per cent lower than the monthly average of 527 recorded between July 2014 and June 2015 and 48 per cent less still than the average of 795 recorded between July 2013 and June 2014.

The improvement comes, primarily, from upgrading the region’s signals with low energy and low maintenance LED ‘aspects’ – the optical unit that displays the signal colour. This project was carried out by TfGM’s traffic signal maintenance contractor, Siemens, and was completed in April 2014.

The aspect replacement project is expected to save US$13.6 million (£9.8 million) over the first ten years by reducing both the need for regular maintenance and energy consumption. The improvement also comes from Siemens working in a more efficient manner, focusing more on pre-emptive maintenance rather than reacting to faults.

TfGM Committee Chair, Councillor Andrew Fender, said: “Traffic signals are a vital part of the region’s highways network, and through them we help to manage 2.1 billion trips on the Greater Manchester road network each year, so it’s excellent news that they are performing almost twice as well as they were three years ago and costing less money to run and maintain.

“We’ll continue to review and, where possible, further improve our signal maintenance procedures to help make sure that there are even fewer traffic light failures in the future.

    The steep drop in fuel prices and its effect on transportation in India, US and UK
    Industry insight from Steer Davies Gleave notes that increases in oil production and lower projected global demand growth for crude oil have contributed to declines in fuel prices, beginning in June 2014 and falling 70 per cent to the lowest point in January 2016. However, the impact of changing fuel prices is not uniform across transportation modes. For instance, in India, retail fuel prices have declined by only 20-25 per cent as a result of the central government increasing the excise duties to shore

    Most EV charging ‘takes place at home’
    New analysis by plug-in vehicle campaign Go Ultra Low suggests that British motorists could no longer have to rely on the conventional petrol station. More than 90 per cent of electric vehicle (EV) charging takes place at home while total charging volumes have almost tripled since 2014, according to new usage data from leading infrastructure provider Chargemaster. Coupled with bumper uptake of plug-in vehicles – more than 14,500 were registered in the first half of 2015 – the new findings point to the po

    Turning off red light cameras costs lives, new research shows
    Red light camera programs in 79 large US cities saved nearly 1,300 lives through 2014, researchers from the Insurance Institute for Highway Safety (IIHS) have found. Shutting down such programs has cost lives, with the rate of fatal red-light-running crashes shooting up 30 per cent in cities that have turned off cameras. Red-light-running crashes caused 709 deaths in 2014 and an estimated 126,000 injuries. Red light runners account for a minority of the people killed in such crashes. Most of those killed
