Simulating cyclist behaviour: An examination of what we know about this subject and how we should go further

Cycling as a mode of transport is getting increasingly more attention from academics and governments around the world. It improves the physical and mental well being of citizens, it is efficient in terms of space and it provides economic benefits. However, traffic engineers and urban planners of these cities currently lack the means to...

Dynamic model-based method for the analysis of ship behavior in marine traffic situation

With the continual development of modern transportation technology and artificial intelligence technology, how to recognize the complex phenomenon of ship behavior existing in maritime traffic has become a hot topic. Maritime traffic is a complex system, the emergence of ship behavior is a leading cause of traffic complexity, and make up the...

Breakdown Phenomenon Study in the Bidirectional Pedestrian Flow

Pedestrian dynamics has been being a popular research area. In this paper, breakdown probability in the bidirectional flow that includes pedestrians with heterogeneities is investigated. Reaction time appears to have the most pronounced breakdown proba- bility, followed by desired velocity and then body size. The relationship between the start...

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

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 ?...

Swarm Optimization Algorithm Based On Social Force Model

Improving the Nomad microscopic walker model

This paper presents the results of two calibration efforts and improvements of the Nomad microscopic walker model. Each calibration consisted in comparing the outcome of 19 sets of model parameters with results from laboratory experiments. Three different flows were used in the calibrations: bidirectional, unidirectional and a narrow bottleneck....
