Deventer’s version of intelligence: all traffic lights in this city in the eastern part of the Netherlands to become iTLCs

Last year was an invitation for more and now, delivery is imminent: the pilot in the city of Deventer (eastern part of the Netherlands) with traffic light priority for the emergency services, public transport and freight traffic at five intelligent Traffic Light controllers (iTLCs) will soon be continued. All 55 VRIs in this Dutch town are currently being converted into iTLCs, with participating partners taking part with (many) more vehicles. This makes traffic control in Deventer ‘smart intelligent’; iTLC truly is ‘the new normal’ here.

Emergency services on the way to an accident are automatically given green light by iTLCs in Deventer, whereas other traffic is warned about their approach and directed away from the junction. Under certain conditions, other participants in the pilot, such as public transport companies and transport companies, take priority over other road users. Early 2019, this prioritisation was cautiously tested with a limited number of iTLCs in Deventer. It appeared that the participants were very satisfied with the improved safety (both for themselves and fellow road users) and with the improved traffic flow. The new phase, called ‘Deventer smart intelligence’, is a direct result of an explicit request from last year’s participants, Vincent Habers, senior ITS consultant on behalf of Talking Traffic explains. ‘All participating parties have clearly noticed the positive effects of the iTLCs. Scaling up the number of iTLCs is, therefore, a logical step to take. This makes it even more attractive for the emergency services, public transport and the logistics sector to increase the number of participating vehicles.’

Expansion

In the new phase, all participants are intensively supervised for about three to six months. All experiences are monitored and used to make adjustments, where necessary. Habers: ‘Despite this being a joint investment with all participating parties aimed at learning even more, it’s no longer a pilot: this is the new normal. More and more providers and participants will join and we’re set to continue after those six months. Afterwards, those 55 iTLCs will continue to operate with their new functionalities.’ The new prioritisation phase in Deventer coincides with an expansion on another front: retractable bollards (the posts that can sink into the ground to provide controlled access) and barriers will also be controlled from the Talking Traffic architecture. This can save crucial time for emergency services in the event of an accident.
