40% of all traffic jams are caused by motorists braking unexpectedly. The flow of traffic can be improved by providing real-time driving advice to motorists. Technolution’s smart app FlowPatrol does exactly that: it gives driving recommendations. And if it is connected to FlowRadar, it can receive 30x more information to use to calculate its advice.
Personal driving advice on your dashboard
A trial with smart apps that improve flow on the A58 between Tilburg and Eindhoven was started in 2015. Some 1,500 regular road users have since been using FlowPatrol under the Spookfiles A58 (‘Phantom Jams A 58’) project. As soon as a traffic jam appears in the distance, the app warns the motorist to adjust his speed. Half of the users subsequently comply with the app’s recommendation, says program manager Jan Bosma: “That’s a good score. We’re already seeing improvements; as long as you have enough users, this app can really make a difference.”
FlowRadar: interaction between vehicles and the roadside
In 2016, we added a cooperative device called FlowRadar to the app. FlowRadar uses Wifi-P to communicate with the roadside and with other FlowRadars. Once a sufficient number of motorists starts using it, this provides a much more detailed picture of the situation on the road, which in turn makes it possible to offer more accurate driving advice through the app. We are planning to provide 700 users with a FlowRadar for this trial.
Spookfiles A58 is a PCP (pre-commercial procurement) construction, in which we form a consortium with NXP and Dynniq. This PCP construction has been spread across three levels, each of which has two consortiums: for data provision, for the apps and for communication between the road and the app. In addition, we are integrally working together with the other consortiums on secure Wifi-P (PKI) communication. Technolution developed the tailor-made FlowRadar from our development platform BloqBase.
From ‘Phantom Jams’ to ‘Creating Flow Together’
FlowRadar is a step in the direction of autonomous vehicles. The ultimate goal is to let road users really become part of the traffic, supported by individual travel advice. We’re already doing that by giving traffic jam warnings and speed recommendations. But in the future we’re thinking in terms of context information, such as lane advice and green time prediction for traffic lights. Road managers also benefit from these facilities because it allows them to optimize and individualize their management of their network from the traffic control center.
Spookfiles A58 is a partnership between the Dutch Ministry of Infrastructure and the Environment, Platform Beter Benutten, SRE City Region Eindhoven and market players.
