Impacts of car-following behaviour on traffic flow capacity at sags

Improving the road network performance with dynamic route guidance by considering the indifference band of road users

When applying dynamic route guidance to improve the network performance, it is important to balance the interests of the road authorities and the road users. In this paper we will illustrate how bounded rationality and indifference bands can be taken into account in dynamic route guidance to improve the network performance while respecting the...

Modeling driving behavior and traffic flow at sags (paper)

Sags are freeway sections along which gradient changes significantly from downwards to upwards. Sags are often bottlenecks in freeway networks. Capacity decreases due to changes in car-following behavior. We present a microscopic traffic flow model that describes driving behavior and traffic flow dynamics at sags. The model includes a new...

Mainstream traffic flow control at sags (poster)

We present a new control strategy that aims to reduce total delay at sags. The strategy is based on the concept of mainstream traffic flow control. The traffic density at the bottleneck area is regulated in order to keep it slightly below the critical density, hence preventing traffic from breaking down while maximizing outflow. Density is...

Mainstream traffic flow control at sags

Sags are freeway sections along which the gradient changes significantly from downwards to upwards. The capacity of sags is significantly lower than the capacity of normal sections. As a result, sags often become bottlenecks in freeway networks, causing the formation of congestion in conditions of high traffic demand. Congestion results in a...

Mainstream traffic flow control at sags

Sags are freeway sections along which the gradient changes significantly from downwards to upwards. The capacity of sags is considerably lower than the capacity of normal sections. Consequently, sags are often freeway bottlenecks. Recently, several control measures have been proposed to improve traffic flow efficiency at sags. Those measures...

Human Factors of Automated Driving: Predicting the Effects of Authority Transitions on Traffic Flow Efficiency

Automated driving potentially has a significant impact on traffic flow efficiency. Automated vehicles, which possess cooperative capabilities, are expected to reduce congestion levels for instance by increasing road capacity, by anticipating traffic conditions further downstream and also by accelerating the clearance of congestion. However, the...

Connected variable speed limits control and vehicle acceleration control to resolve moving jams

The vision of intelligent vehicles traveling in road networks has prompted numerous concepts to control future traffic flow, one of which is the in-vehicle actuation of traffic control signals. The key of this concept is using intelligent vehicles as actuators for traffic control systems, replacing the traditional road-side systems. Under this...

Empirical longitudinal driving behaviour in case of authority transitions between adaptive cruise control and manual driving

Automated vehicles are expected to have a substantial impact on traffic flow efficiency, safety levels and levels of emissions. However, Fields Operational Tests suggest that drivers may prefer to disengage Adaptive Cruise Control (ACC) and resume manual control in dense traffic conditions and before performing manoeuvres such as lane changing....
