BAM Infra – Improved traffic flow

BAM Infra is the premier partner for infrastructure connections in the Netherlands. They offer innovative solutions and do so in their own unique way. Slightly differently. Just a little smarter. And always safely and sustainably. That is what they stand for. That is what they strive for. BAM Infra Nederland is a subsidiary of Royal BAM Group, a successful European construction group, which unites operating companies in the two business lines Construction & Real Estate and Infrastructure as well as in the area of public–private partnerships. BAM is listed on Euronext Amsterdam.

Challenge

Until recently, induction loops in the asphalt or roadside systems were necessary to measure the flow of traffic. In the current digital age, however, many more sources are available, such as data from moving vehicles – an innovation that BAM Infra uses. After a summer of non-stop work, BAM Infra finalized a complete renovation of the Gein Bridge in Driemond in the autumn of 2017. The province of Noord-Holland wanted to replace the bridge because it was ‘in a very bad condition’. At the same time, the crossing at Driemond was improved too. The purpose of all this work was to improve the safety and traffic flow of the road.

Benefits

At Driemond, initial measurements of the new situation show significantly improved traffic flows. The lines in the figure show the current time losses (red) compared with the average time losses for the past years (blue). When it comes to tenders or visualization of the effects of temporary traffic systems – a speed reduction or changed road situation for example – BAM also monitors the traffic situation through the use of floating car data from ODIQ.

This development is in line with the broader vision of BAM Infra in which data plays a central role. The same applies to the infrastructure. Thanks to sensors, cameras, public data and the deployment of satellites, among other things, we are learning ever more about how infrastructure is used. And how this information can be used to create added value for users, managers and the local area.

* floating car data: Floating car data, at its most basic level, consists of GPS data from smartphones and apps such as the Google Maps app on your smartphone. This ‘data’ contains information about aspects such as travel times and speeds.

How Brussels used ODIQ as an alternative to traffic cameras

Brussels is the capital of Belgium and Europe. With 1.2 million inhabitants it counts as one of Belgium’s biggest cities. During the pandemic, Brussels used the reduced traffic in 2020 to accelerate their mobility plans. To follow up on the adjustments in real-time and historically, Brussels Mobility contacted Localyse.

Localyse monitors all major access routes in Brussels

Mobiris, the dispatching center of Brussels Mobility, has about 500 cameras to monitor more than 350 km of roads in the Brussels-Capital Region, ‘one might think that’s plenty’ but in reality it’s far from enough. That’s why Mobiris, was looking for an addition/alternative to cameras. Localyse, introduced Brussels Mobility to ODIQ which uses Google Maps’ Floating Car Data, this is worldwide GPS data from smartphones on which Google Maps is installed… an inexhaustible, representative data source.

A versatile tool

ODIQ can be used for carrying out traffic analyses before a decision or intervention and after. Furthermore, the tool allows to detect bottlenecks intersection by intersection, and find out the reason for them: whether it is a wrongly adjusted traffic light, an illogical right of way or a bicycle lane that should be moved with ODIQ, it all becomes clear.

Traffic situation monitoring team lead

At trade fair we saw a presentation on ODIQ, and it seemed to be the ideal tool for gaining quick and easy insight into traffic situations by mapping traffic flow in real time.
