Improving Traffic Efficiency With Lane Guidance Based on Desired Speeds

Mahajan, N. (author), Hegyi, A. (author), Hoogendoorn, S.P. (author), van Arem, B. (author)

Drivers initiate a discretionary lane change when they perceive an anticipated improvement in their own driving condition from moving to another lane. However, such a lane change can slow down other vehicles on the target lane, and even worse initiate a disturbance. In this work, we argue that the blocking effect triggered by individual lane...

Extension of a static into a semi-dynamic traffic assignment model with strict capacity constraints

Brederode, L.J.N. (author), Gerards, Lotte (author), Wismans, Luc (author), Pel, A.J. (author), Hoogendoorn, S.P. (author)

To improve the accuracy of large-scale strategic transport models in congested conditions, this paper presents a straightforward extension of a static capacity-constrained traffic assignment model into a semi-dynamic version. The semi-dynamic model is more accurate than its static counterpart as it relaxes the empty network assumption, but,...

Quantification and control of disruption propagation in multi-level public transport networks

Yap, M.D. (author), Cats, O. (author), Törnquist Krasemann, Johanna (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

Due to the multi-level nature of public transport networks, disruption impacts may spill-over beyond the primary effects occurring at the disrupted network level. During a public transport disruption, it is therefore important to quantify and control the disruption impacts for the total public transport network, instead of delimiting the...

Enhancing crowd monitoring system functionality through data fusion: Estimating flow rate from wi-fi traces and automated counting system data

Duives, D.C. (author), van Oijen, T.P. (author), Hoogendoorn, S.P. (author)

Crowd monitoring systems (CMSs) provide a state-of-the-art solution to manage crowds objectively. Most crowd monitoring systems feature one type of sensor, which severely limits the insights one can simultaneously gather regarding the crowd’s traffic state. Incorporating multiple functionally complementary sensor types is expensive. CMSs are...

Empirical MFDs using Google Traffic Data

Knoop, V.L. (author), van Erp, P.B.C. (author), Leclercq, Ludovic (author), Hoogendoorn, S.P. (author)

<br/>The Macroscopic Fundamental Diagram (MFD) describes the relation between accumulation and speed in a zone. While theoretically expected, empirical validations have been done with limited numbers of floating car (e.g., taxi) data, and loop detectors. This paper will verify existence, shape and crispness of the MFD using Floating Car Data ...

The influence of the interaction characteristics on the movement dynamics of pedestrians

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

One of the fundamental properties of pedestrian simulation models is their capability to predict the future movement dynamics of pedestrians depending on the current state of the pedestrian traffic flow, more specically the walking behaviour of neighbouring pedestrians. This paper investigates the influence of the interaction characteristics 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...

Traffic dynamics: Its impact on the macroscopic fundamental diagram

Knoop, V.L. (author), van Lint, J.W.C. (author), Hoogendoorn, S.P. (author)

Literature shows that–under specific conditions–the Macroscopic Fundamental Diagram (MFD) describes a crisp relationship between the average flow (production) and the average density in an entire network. The limiting condition is that traffic conditions must be homogeneous over the whole network. Recent works describe hysteresis effects:...

Macroscopic Traffic Dynamics with Heterogeneous Route Patterns

Leclercq, L. (author), Parzani, Céline (author), Knoop, V.L. (author), Amourette, Jennifer (author), Hoogendoorn, S.P. (author)

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...

Extension of Edie's Definitions for Pedestrian Dynamics

Van Wageningen-Kessels, F.L.M. (author), Hoogendoorn, S.P. (author), Daamen, W. (author)

Consistent definitions of important variables in pedestrian flow dynamics are proposed. They are based on the definition of similar variables for road traffic flow from the 1960's by Edie. The definitions are extended to include multi-class flows where pedestrians move in different directions or have different characteristics. The new...
