There is a growing interest in the traffic community about the relation between traffic data quality and the efficiency of traffic management. Data collection is expensive and if the same level of traffic performance can be reached with less data or if traffic management becomes more efficient with better data, then that is interesting for a lot...

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...

On a motorway, drivers make decisions on their speed. It has been shown that drivers change their acceleration only at specific times and not continuously. Lane changes are also made at discrete moments in time. This paper determines the moments when drivers change their acceleration and moments when they change lanes. Fitting longitudinal and...

The delay caused by an incident depends on many variables. This paper introduces an analytical expression for the delay, describing the location and length of the queue by shockwave theory. As long as the congestion remains on the same link, delay is proportional to the square of the duration, even in case the outflow is reduced by a junction...

In the last decade many multi class kinematic wave (MCKW) traffic ow models have been proposed. MCKW models introduce heterogeneity among vehicles and drivers. For example, they take into account differences in (maximum) velocities and driving style. Nevertheless, the models are macroscopic and the ow is modeled as a continuum flow, without...

Due to increasing exchange of data between measurement sites, the area over which traffic control is applied increases. This leads to three new challenges: (1) working with the large quantities of data (transmit, store), (2) estimating the traffic state, (3) controlling a large area with many controllers (and hence large solution space). This...

Dynamic Traffic Management (DTM) aims to improve traffic conditions. DTM usually consists of two steps: first the current traffic is estimated, then appropriate control actions are determined based on that estimate. In order to estimate and control the traffic, a suitable traffic flow model that reproduces the properties of traffic well must be...

Few Active Traffic Management measures proposed in the past consider the distinction of different vehicle classes. Examples of vehicle-class specific measures are truck lanes and high-occupancy/toll (HOT) lanes. We propose that the distinction of different vehicle classes, with different flow characteristics and societal and economic function,...

The duration of incidents is a stochastic variable with a variation spread. This chapter analyzes the consequences of this stochastic nature of the duration in terms of delay. It uses shockwave theory to describe traffic states. As opposed to a point queue model, the head and the tail of the queue are separately modeled and in this way the...

This paper introduces a topic which is of growing interest in the traffic control and management community, namely the relation between traffic data quality and the efficiency of traffic management. After some explanatory background and state of the art, it will become clear that no standard approach is available for traffic engineers to...

Incidents can affect the flow in non?incident direction due to rubbernecking. To this date, only homogeneous rubbernecking behaviour has been assessed. This study provides insights into inter?driver heterogeneity in rubbernecking behaviour while passing an incident site. We use empirical trajectory data obtained from a helicopter?mounted video...

With current techniques, traffic monitoring and control is a data intensive process. Network control on a higher level, using high level variables, can make this process less data demanding. The macroscopic fundamental diagram relates accumulation, i.e. the number of vehicles in an area, to the network performance, but only holds for situations...

Disaster evacuation studies are important but difficult or impossible to conduct in the real world. Evacuation simulation in a virtual world can be an important tool to obtain data on the escape and choice behavior of people. However, to obtain accurate “realistic” data, the engagement of participants is a key challenge. Therefore, we describe...
