A field experiment investigated factors expected to influence yielding by motorists to a pedestrian waiting to cross a city street. One-hundred and sixty motorists passing through a marked crosswalk were participants. In addition, data were gathered on 120 baseline motorists who passed through the test intersection when a pedestrian was not present. A comparison of the age composition of the ex...

The left turn lane capacity is highly influenced by the presence of pedestrians under shared signal phasing. Pedestrian crossing time can be pedestrian platoon maneuver influence traffic settings, crosswalk length and bidirectional interactions pedestrian, due to that turning vehicles movement may significantly affected. However, existing estimation methods lanes did not consider those factors....

We propose an extension to the stateof-the-art Faster R-CNN detection model for multimodal pedestrian detection from RGB-D images. The proposed architectures address this problem by fusing convolutional neural network (CNN) representations. We elaborate two architectures, which primarily differ in the position of the fusion inside the model, and further compare several static and parametrized f...

5 This study establishes a mathematical model that can represent the conflicting effects of two 6 pedestrian streams with an oblique intersecting angle in a large crowd. In a previous study, a 7 controlled experiment in which two streams of pedestrians were asked to walk in designated 8 directions was used to model the bi-directional pedestrian stream of certain intersecting angles. In this 9 s...

Modern roundabouts have become very popular in North America over the last decade. This popularity can be attributed to their great success in Europe and Australia. The prevalence of roundabouts has generated significant debate over their accessibility for pedestrians. With almost uninterrupted traffic flows, it is difficult for the visually impaired to determine safe gaps relying on auditory c...

Facilitating safe pedestrian road crossings is a major prerequisite for urban environments. In multiple cities around the world, 3D crosswalks have been painted, which provoke an optical illusion, of e.g., crosswalk floating above road, in car drivers who approach crosswalk. However, to date, no detailed study users’ safety related perceptions on has conducted. Hence, we investigated drivers’ a...

Both humans and the sensors on an autonomous vehicle have limited sensing capabilities. When these limitations coincide with scenarios involving vulnerable road users, it becomes important to account for these limitations in the motion planner. For the scenario of an occluded pedestrian crosswalk, the speed of the approaching vehicle should be a function of the amount of uncertainty on the road...

Autonomous vehicles have gained popularity in recent years, but they are still not compatible with other vulnerable components of the traffic system, including pedestrians, bicyclists, motorcyclists, and occupants smaller such as passenger cars. This incompatibility leads to reduced system performance undermines safety comfort. To address this issue, authors considered pedestrian crosswalks whe...

The Empirical Bayesian (EB) Method, currently the industry standard for before-andafter collision analysis, was used to perform tests on the efficacy of high-visibility school (yellow, continental-style) crosswalks in the City of San Francisco. Statistical analysis compared the number of collisions predicted for the after period had the enhanced crosswalks not been installed to the number of co...
