Pilot study on in-car advice of green and blue waves

In the Netherlands, researchers are carrying out a pilot study using the Radio Dynamic Speed Advice (RDSA) app, developed by Dutch company Amaryllo MMG, specialist in radio technology, aided by navigation solution solutions provider NNG, who integrated the app into their software. The study aims to determine how intelligent apps can positively influence human behaviour in traffic. Around 300 participants driving on a busy access road are currently being provided with in-car advice on how to catch green wave

In the Netherlands, researchers are carrying out a pilot study using the Radio Dynamic Speed Advice (RDSA) app, developed by Dutch company 6592 Amaryllo MMG, specialist in radio technology, aided by navigation solution solutions provider NNG, who integrated the app into their software. The study aims to determine how intelligent apps can positively influence human behaviour in traffic.

Around 300 participants driving on a busy access road are currently being provided with in-car advice on how to catch green waves. They are also being warned of approaching emergency vehicles.

When a vehicle involved in the study passes over an inductive loop, the traffic signal control system calculates a recommended speed to allow the driver to arrive at the next traffic signal during its green phase. The control system is equipped with a transmitter that transmits this advice by means of an FM radio frequency of 105.1 MHz. Tucked away in the connecting cable of the pilot study driver’s navigation system is an FM receiver that picks up the signal. The RDSA app displays this advice on the screen.

Staff in an emergency vehicle can use a responder to request the activation of the blue wave. This signal is picked up by the traffic signal control system: the system not only times the traffic signals to turn green for the approach of the emergency vehicle (a service already in use in the Netherlands) but also informs nearby pilot study drivers by means of the FM transmitter.

According to the researchers, say the technology used in the pilot is proven technology and thus highly cost-effective. The transmitters and receivers are inexpensive and easy to implement in existing traffic signal control systems and navigation systems. Modifications in navigation software are also easy to introduce. NNG was already in the process of adapting its navigation software for third-party apps. RDSA is a good example of how this is leading to smart, cost-effective applications.

Other participants in the study include Amaryllo, whose FM transmitter was installed in an existing 769 Imtech-101 Peek Traffic signal control system that was already equipped with the Odysa green wave module from DTV Consultants, Belgian company 6593 Be-Mobile who provided the control platform for the RDSA service, and 6594 Goudappel Coffeng who will be responsible for the evaluation of the pilot study.

Although Floating Vehicle Data (FVD) or probe vehicle fleets have been around for about a decade, the idea behind them is of course much older: from probe vehicles that flow with the traffic it should be possible to get a precise, fast and spatially near-complete picture of the prevailing traffic flow conditions in an area under surveilla

    Automatic signal control to prevent emergency vehicle collisions?
    Field trials under way in Arizona promise eradication of accidents between emergency vehicles at intersections – as part of a national focus on ‘intelligent signal’ infrastructure. Collisions between police cars, ambulances and fire crews as they reach intersections at the same time, with equal priority given by all signals set on red, are as serious as they sound absurd. For emergency teams and those in need of their help, the consequences are dire. The solution could come from application of connected veh

    Proposed system to take guesswork out of choosing a freeway lane
    A fledgling advanced lane management assist system can take the guesswork out of selecting the right lane on a congested freeway, as its inventor Robert Gordon explains. As drivers we’ve all done it and control room staff see it all the time – motorists on congested freeways switching into what they perceive is a faster lane, only to come to a halt a few moments later and watch vehicles in the other lanes continue to move past. Now, by re-analysing readily available data in an advanced lane management as
