Patients with peripheral field loss complain of colliding with other pedestrians in open-space environments such as shopping malls. Field expansion devices (e.g., prisms) can create artificial peripheral islands of vision. We investigated the visual angle at which these islands can be most effective for avoiding pedestrian collisions, by modeling the collision risk density as a function of bear...

One of the main challenges for transportation engineers is the consideration of pedestrian safety as the most vulnerable aspect of the transport system. In many countries around the world, a large number of accidents recorded by the police are composed of accidents involving pedestrians and vehicles, for example when pedestrians may be struck by passing vehicles when crossing the street. Carefu...

The study of crowd dynamics is interesting because of the various self-organization phenomena resulting from the interactions of many pedestrians, which may improve or obstruct their flow. Besides formation of lanes of uniform walking direction and oscillations at bottlenecks at moderate densities, it was recently discovered that stop-and-go waves [D. Helbing et al., Phys. Rev. Lett. 97, 168001...

Microscopic approaches to the simulation of pedestrian dynamics rely on modelling behaviour individual agents and their mutual interactions. Regarding spatial resolution, microscopic simulators are either based continuous (SpaceCont) or discrete (SpaceDisc) approaches. To combine advantages both approaches, we propose integrate SpaceCont SpaceDisc into a hybrid model. Such approach allows simul...

The standard definition of pedestrian density produces scattered values, hence, many approaches have been developed to improve the features estimated density. This paper provides a review generally applied methods and presents general framework based on various kernels that bring desired properties estimates (e.g., continuity) incorporate ordinarily used methods. kernel concept considers each a...

Real-Time Pedestrian detection and tracking methods are the state-of-the-art techniques in present driver assistance systems. However, pedestrian detection and tracking methods that exploit the parallel processing capabilities of heterogeneous high performance computing devices such as FPGAs (or GPUs) with sensor fusion(camera and Lidar), a technology that potentially will replace ECUs in a com...

This paper presents a traffic simulation approach for evaluating the pedestrian behaviour by developing a model which includes pedestrians in a vehicular micro-simulation model i.e. PARAMICS that provides a default mechanism for simulating pedestrian movements. This approach is demonstrated by using a case study of a signalized intersection having large pedestrian flow interacting with large ve...
