How do the recognizability and driving styles of automated vehicles affect human drivers’ gap acceptance at T- Intersections?

Reddy, N. (author), Hoogendoorn, S.P. (author), Farah, H. (author)

Future traffic will be composed of both human-driven vehicles (HDVs) and automated vehicles (AVs). To accurately predict the performance of mixed traffic, an important aspect is describing HDV behavior when interacting with AVs. A few exploratory studies show that HDVs change their behavior when interacting with AVs, being influenced by...

Does ride-sourcing absorb the demand for car and public transport in Amsterdam?

Narayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

The emergence of innovative mobility services, is changing the way people travel in urban areas. Such systems offer on-demand service (door-To-door or stop-To-stop, individual or shared) to passengers. In addition to providing flexible services to passengers, past studies suggested that such services could effectively absorb the demand for...

Using advanced adaptive cruise control systems to reduce congestion at sags: An evaluation based on microscopic traffic simulation

Goni Ros, B. (author), Schakel, W.J. (author), Papacharalampous, Alexandros E. (author), Wang, M. (author), Knoop, V.L. (author), Sakata, Ichiro (author), van Arem, B. (author), Hoogendoorn, S.P. (author)

Sags are roadway sections along which the gradient increases gradually in the direction of traffic. Sags are generally bottlenecks in freeway networks. Previous research suggests that traffic management measures using advanced Adaptive Cruise Control (ACC) systems could reduce congestion on freeways, but little is known about their potential...

Review of maritime traffic models from vessel behavior modeling perspective

Zhou, Y. (author), Daamen, W. (author), Vellinga, T. (author), Hoogendoorn, S.P. (author)

The importance of maritime transport keeps increasing with the trade globalization. With the growing demand for waterborne transport, vessel traffic flows are also expected to increase. This paper reviews maritime traffic models from the vessel behavior modeling perspective. The maritime traffic models include the models for vessel traffic both...

Passenger Route Choice and Assignment Model for Combined Fixed and Flexible Public Transport Systems

Narayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

The recent technological innovations have given rise to innovative mobility solutions. Public transport systems combining such services need novel models for the design of services. We develop a multimodal route choice and assignment model for combined use of line/schedule based public transport systems (fixed public transport) and demand...

State-of-the-art of port simulation models for risk and capacity assessment based on the vessel navigational behaviour through the nautical infrastructure

Bellsola Olba, X. (author), Daamen, W. (author), Vellinga, T. (author), Hoogendoorn, S.P. (author)

Ports play an increasingly important role in the freight transportation chain due to containerization. High vessel flows and higher densities increase the relevance of the non-terminal related processes. Several simulation models have been developed in the recent decades with different goals, but their abilities to represent realistic vessel...

Performance Assessment of Fixed and Flexible Public Transport in a Multi Agent Simulation Framework

Narayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

The emergence of innovative mobility solutions that offer flexible transport services, is changing the way urban public transport systems will be designed. Such mobility solutions offer on demand transport services and hence can solve the problems inherent with traditional line based and schedule based public transport systems. It is essential...

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

Taale, H. (author), Hoogendoorn, S.P. (author), Legius, P. (author)

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...

Estimating port network traffic capacity

Bellsola Olba, X. (author), Daamen, W. (author), Vellinga, T. (author), Hoogendoorn, S.P. (author)

Port capacity is a relevant parameter to estimate the expected performance of a port facility. Many simulation models have been used to predict traffic in ports and waterways, but they do not include provisions for estimating the port’s capacity. The innovative method presented here determines a Port Network Traffic Capacity (PNTC) based on...

An Area-Aggregated Dynamic Traffic Simulation Model

Knoop, V.L. (author), Hoogendoorn, S.P. (author)

Microscopic and macroscopic dynamic traffic models not fast enough to run in an optimization loop to coordinate traffic measures over areas of twice a trip length (50x50 km). Moreover, in strategic planning there are models with a spatial high level of detail, but lacking the features of traffic dynamics. This paper introduces the Network...

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

Varotto, S.F. (author), Hoogendoorn, R.G. (author), Van Arem, B. (author), Hoogendoorn, S.P. (author)

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....

This paper investigates at an aggregated (macroscopic) scale the effects of route patterns on a road network. Four main variables are considered: the production, the mean speed, the outflow and the mean travel distance. First, a simple network with heterogeneous travel distances between origins and destinationsis studied by simulation. It...

The Many Roles of the Relaxation time Parameter in Force based Models of Pedestrian Dynamics

Johansson, F. (author), Duives, D.C. (author), Daamen, W. (author), Hoogendoorn, S.P. (author)

In force based models of pedestrian traffic, the relaxation time, ?, is related to the time it takes a pedestrian to adapt its motion to its preferences. An example of this is linear acceleration, but ? is also connected to how the agent adjusts to spatial variations in its preferred velocity, and affects evasive maneuvers. These many roles of ?...

Investigation of driving behaviour transition during evacuation and its implication for traffic flow operations based on an open-source traffic simulation platform

Yuan, Y. (author), Pel, A.J. (author), Hoogendoorn, S.P. (author)

Earlier studies have shown how driving behaviour during emergency evacuation is different from that under “normal” conditions. At the same time, most evacuation studies (where the driving performance is explicitly accounted for) were conducted under the assumption of a fully activated emergency environment. However, the transition phase in...
