Kunstmatige intelligentie in verkeer en vervoer

Kunstmatige of artificiële intelligentie, kortweg AI, speelt een steeds grotere rol in ons leven. Ook ons werkterrein verkeersmanagement kan er niet omheen: AI heeft zich al aardig weten binnen te werken in onze data-analyses en verkeerslichten. In deze bijdrage schetsen de auteurs de stand van zaken. Wat is AI? Wat kunnen we ermee? En met welke...

Ramp Metering with Microscopic Gap Detection Algorithm Design and Empirical Acceleration Verification

Freeway on-ramp areas are susceptible to traffic congestion during peak hours. To delay or prevent the onset of congestion, ramp metering can be applied. A Ramp Metering Installation (RMI) controls the inflow from the on-ramp to the main line so that the total flow can be kept just below capacity. Current ramp metering algorithms apply...

The impact of a dedicated lane for connected and automated vehicles on the behaviour of drivers of manual vehicles

Connected and automated vehicles (CAVs) are expected to enhance traffic efficiency by driving at shorter time headways, and traffic safety by shorter reaction times. However, one of the main concerns regarding their deployment is the mixed traffic situation, in which CAVs and manually driven vehicles (MVs) share the same road. This study...

Design and operation of dedicated lanes for connected and automated vehicles on motorways: A conceptual framework and research agenda

Dedicated Lanes (DLs) have been proposed as a potential scenario for the deployment of Automated and/or Connected Vehicles (C/AVs) on the road network. However, evidence-based knowledge regarding the impacts of different design configurations, utilization policies, and the design of their access/egress on traffic safety and efficiency is...

Improving traffic management through consideration of uncertainty and stochastics in traffic flow

In a bid to cost-effectively tackle congestion, traffic management is often seen as a key option to utilise road capacity. Prior to the application of traffic management measures, a-priori analysis allows the effectiveness of measures to be judged and where necessary adapted. However, current approaches do this without considering the effects...

Lane Change Behavior on Freeways: An Online Survey Using Video Clips

Freeways forman important part of the road network. Yet, driving behavior on freeways, in particular lane changes and the relation with the choice of speed, is not well understood. To overcome this, an online survey has been carried out. Drivers were shown video clips, and after each clip they had to indicate what they would do after the moment...

Improvement of Network Performance by In-Vehicle Routing Using Floating Car Data

This paper describes a study which gives insight into the size of improvement that is possible with individual in-car routing advice based on the actual traffic situation derived from floating car data (FCD). It also gives an idea about the required penetration rate of floating car data needed to achieve a certain degree of improvement. The...

Metering with Traffic Signal Control: Development and Evaluation of an Algorithm

For some on-ramps, which cause congestion on the motorway, it is not possible to install a ramp metering system for geometric or other reasons. But sometimes it is possible to meter traffic with the traffic lights of nearby intersections in such a way that the situation on the motorway improves and on the urban network the situation does not get...

Stedelijk verkeersmanagement: Problemen van nu en richtingen voor de toekomst

Datafusie - wat wordt ermee bedoeld en wat heb je eraan?

Heb je het met iemand over verkeersdata, dan valt – naast de zo populaire kreet ‘big data’ – bijna altijd de term datafusie. In veel gevallen is het echter helemaal niet zo duidelijk wat daar nu precies mee wordt bedoeld en waarom het zinvol zou zijn. In deze tutorial daarom een korte introductie. We gaan daarbij vooral in op de kwaliteit van...
