Upsala installs Actibump traffic calming

The Swedish city of Uppsala has become the third city in the country to install 5955 Edeva’s Actibump in a bid to improve traffic congestion on a busy four-lane road.

According to Edeva, its Actibump traffic calming solution creates road safety through greater compliance with speed limits.

Actibump is a metal trough six centimetres deep in the road surface, which the developers say is deep enough for drivers to notice, but not so deep as to cause damage to the vehicle.

The system utilises a roadside radar unit to monitor traffic; if a vehicle is exceeding the speed limit, the metal trough is activated and its flat metal plate pivots downwards, exposing an edge that the vehicle bounces over. Vehicles obeying the speed limit pass the barrier unimpeded, helping to maintain a smooth traffic flow.

Uppsala project manager Martin Öberg says: “According to our studies vehicles are travelling 40 per cent too fast on this road. Hopefully we can reduce that figure. Accessibility will be improved for public transport and operation of snow clearing vehicles.

Linköping Municipality has commissioned VTI, the Swedish National Road and Transport Institute, to Actibump on a major road in the city which is used by 5,000 vehicles per day. Municipal traffic engineer Jonas Nygren says, “We got a good result. The average speed on the measured distance has been reduced from 36 to 32 km/h.”

    The City of Cape Town has installed an average speed over distance, or average speed enforcement, system on Nelson Mandela Boulevard in its latest attempt to address speeding and promote road safety. The system, supplied by local company Syntell, consists of three sets of cameras that will cover all incoming and outgoing lanes and will become operational later this month, measuring the speed of all vehicles travelling in both directions between the bottom of Nelson Mandela Boulevard and the N2 and M3.

    A new study from the Swedish National Road and Transport Research Institute (VTI) aims to review pedestrian and cyclist solutions on major roads, with or without a central barrier, where the permitted speed limit is between 70 and 90km/h. Reconstructing an existing road with a central barrier is primarily considered as a road safety measure which reduces the risk of head on collisions. A negative effect of this type of design is that conditions for cyclists and pedestrians become difficult, especially when

    New trials show Bluetooth and Wi-Fi signals can be reliably used for measuring travel times and at a lower cost than an ANPR system, but which is the better proposition depends on many factors. Measuring travel times has traditionally relied automatic number plate (or licence plate) recognition (ANPR/ALPR) cameras capturing the progress of vehicles travelling along a pre-defined route. Such systems also have the benefit of being able to count passing traffic and have become a vital tool in dealing with c

    High-speed weigh-in-motion is starting to make its mark on both sides of the Atlantic. As a transit country the Czech Republic experiences a large number of overloaded vehicles, which greatly increase highway maintenance costs. This prompted its Transport Ministry to trial an extension of the capabilities of the existing truck tolling system to allow the dynamic high-speed weighing of cargo vehicles. In effect the tolling enforcement gantries become weigh-in-motion (WIM) locations.
