‘Smart’ traf­fic lights cut jour­ney times and jams

Birmingham Post - - NEWS - Tony Larner News Ed­i­tor

A‘SMART traf­fic lights’ trial in Birm­ing­ham has been hailed a jam-bust­ing suc­cess – and could now be rolled out across the city.

The Green Light Ad­vi­sory (GLOSA) in­stalled over a 6km A45 Coven­try Road.

It re­layed im­pend­ing traf­fic light changes to ap­proach­ing cars, al­low­ing driv­ers to ad­just their speed and avoid sharp brak­ing be­tween junc­tions.

Now Trans­port for West Mid­lands has re­vealed the trial scheme has been a huge suc­cess – cut­ting jour­ney times by around seven per cent.

The trial in­volved the tech­nol­ogy be­ing fit­ted to ten junc­tions and de­tails sent to a smart­phone held by a car pas­sen­ger.

The sys­tem pre­dicted the light changes and driv­ers were given the op­ti­mal speed when ap­proach­ing the Op­ti­mal sys­tem stretch Speed was the of junc­tion. The project – a col­lab­o­ra­tion be­tween or­gan­i­sa­tions in­clud­ing Trans­port for West Mid­lands and Birm­ing­ham City Coun­cil – has now won a top trans­port in­dus­try award.

Coun­cil­lor Roger Lawrence, West Mid­lands Com­bined Au­thor­ity port­fo­lio holder for trans­port, said: “Once again the West Mid­lands is be­ing recog­nised as a pi­o­neer in the use of tech­nol­ogy to meet modern trans- port chal­lenges. This award is a tribute to the tal­ent and part­ner­ship work­ing we have here in the re­gion.

“Be­ing at the fore­front of the devel­op­ment of 5G mo­bile tech­nol­ogy and con­nected and au­ton­o­mous ve­hi­cles and the UK’s first Fu­ture Mo­bil­ity Area, we can ex­pect more ex­cit­ing de­vel­op­ments.”

Trans­port chiefs be­lieve that with in­stal­la­tion costs less than £1,000 per junc­tion, the sys­tem could be cheaply and quickly ex­panded to other routes and the open source app could be eas­ily adapted to in car in­for­ma­tion sys­tems or sat­nav de­vices in fu­ture.

With rel­a­tively low set-up costs it could also be adopted by other high­way author­i­ties. The sys­tem will be re­fined with an ex­panded trial in 2019.

It could also prove cru­cial for con­nected and au­ton­o­mous ve­hi­cles which are due to be tested in the West Mid­lands.

Coun­cil­lor Waseem Zaf­far, cab­i­net mem­ber for trans­port and en­vi­ron­ment at Birm­ing­ham City Coun­cil, said: “It is fan­tas­tic news that this in­no­va­tive tech­nol­ogy, which was tested right here in Birm­ing­ham, has won this pres­ti­gious award.

“Any­thing that helps to re­duce con­ges­tion on our roads is to be wel­comed and I am pleased that the suc­cess of the trial means that this sys­tem could now be rolled out fur­ther.”
