The city of Portsmouth in the UK is tackling its traffic congestion problems by introducing new technology from Danish company BLIP Systems, a provider of wireless traffic management solutions.
With the help of BLIP Systems´ UK partner, Smart CCTV, Portsmouth City Council has placed small BlipTrack sensors on the three most congested roads and along the M27/A27 east-west corridor. The sensors measure journey times and speeds, and with this data in hand, the council will be able to warn drivers about queues on VMS (variable message sign) displays, through mobile apps and more. It also provides the city with valuable information about flow, which is useful for planning and optimising traffic.
The installation of the BlipTrack sensors covering the 12 cross-city routes is about one tenth the cost of an ANPR (automatic number plate recognition) camera solution, ITS (intelligent transport systems) UK members were told at their autumn local government conference.
Smart CCTV managing director Nick Hewitson told delegates: “BlipTrack catches upwards of 40% of vehicles, compared with 95% with ANPR. But this is statistically more than adequate for journey time information.”
Depending on driver feedback, the council is considering rolling out the system more widely, said project manager Lee Gilbert at the conference. The solution could also boost the city´s contribution to the Hampshire, Southampton, Portsmouth ROMANCE Traffic and Travel Information Service. Meanwhile Smart CCTV, which is working on several other local authority deployments, is working on a mobile app for drivers.
