We consider a pedestrian tracking system where sensor nodes are placed only at specific points so that the monitoring region is divided into multiple smaller regions referred to as microcells. In the proposed pedestrian tracking system, sensor nodes composed of pairs of binary sensors can detect pedestrian arrival and departure events. In this paper, we focus on pedestrian tracking in microcell...

In road traffic collisions, pedestrian injuries and fatalities account for approximately 11% and 20% of casualties in the USA and the EU, respectively. In many less motorised countries, the majority of victims are pedestrians. The significant influences of vehicle speed, pedestrian speed and pedestrian gait on pedestrian post-impact kinematics have been qualitatively noted in the literature, bu...

Walking is an essential mode of transport. New and improved pedestrian facilities promote walking and provide greater access and mobility within our communities. The NZ Transport Agency has recently updated the procedures for the evaluation of pedestrian improvement projects. The benefit factor applying to new pedestrian trips was increased from $0.50 to $2.70/km, making pedestrian facility imp...

Quantifying the effects of crosswalk length and signal timing on pedestrian walking speed is an important requirement for providing a rational safety assessment and improving existing operational policies at signalized intersections. This study investigates the effects of pedestrian green time (PG), crosswalk length and pedestrian crossing direction on pedestrian walking speed at signalized cro...

Pedestrian detection is one of the most important research contents of road safety. The crucial idea behind such pedestrian safety systems is to protect the driver and pedestrian from any accident. In this paper, a pedestrian feature extraction based on applied log-Gabor filters is presented. The resulting filtered images show desirable segmentation performance which allows support vector machi...

The fluid-flow model is suitable for vehicle traffic on highways but not for pedestrian movements with frequent “stop-and-go” behavior. Considering the change of a mobile’s velocity within a short time is limited due to physical restrictions, therefore a mobile user’s future velocity is likely to be correlated with its past and current velocity. Since Gauss–Markov model captures the essence of ...

Walking time prediction aims to deduce waiting time and travel time for passengers and provide a quantitative basis for the subway schedule management. This model is founded based on transfer passenger flow and type of pedestrian facilities. Chaoyangmen station in Beijing was taken as the learning set to obtain the relationship between transfer walking speed and passenger volume. The sectional ...

Most studies of pedestrian injuries focus on reducing traumatic injuries due to the primary impact between the vehicle and the pedestrian. However, based on the Pedestrian Crash Data Study (PCDS), some researchers concluded that one of the leading causes of head injury for pedestrian crashes can be attributed to the secondary impact, defined as the impact of the pedestrian with the ground after...

There is now increasing emphasis on managing the urban transport for the benefit of all road users, particularly on the promotion of walking and cycling as more environmentally friendly modes of transport. Dynamic traffic signal controls in respond to pedestrian demand have been developed which give the flexibility and control to the network controllers to manage pedestrian and vehicle interact...

In this work, we derive first order continuum traffic flow models from a microscopic delayed follow-the-leader model. Those are applicable in the context of vehicular traffic flow as well as pedestrian traffic flow. The microscopic model is based on an optimal velocity function and a reaction time parameter. The corresponding macroscopic formulations in Eulerian or Lagrangian coordinates result...
