Child Pedestrian Crossing Study – a few updates

We have just completed this study. Analysis of results and full report are being prepared.

The objective of the research is to lay the foundations for examining whether training child-pedestrians’ HP skills while crossing a road may improve their ability to perceive potentially hazardous situations and to predict hazards prior to their materialization.

  • A first step in developing a training program is to form understanding of child-pedestrians’ traffic behavior patterns. Comparing adults and children provides a depiction of what elements in the traffic environment are crucial for the road-crossing task.
  • In the present study, children and adults participant in a two-phase experiment. They observe typical urban scenarios (see Figure 1) from a pedestrian’s point of view (see Figure 2) and a required to: (1) Press a response button each time they feel it is safe to cross. (2) Describe the features that they perceive as relevant for a safe road-crossing decision, i.e., the conceptual model each group of pedestrians has. Participants’ eye-movements were recorded throughout the experiment utilizing a helmet mounted tracker (Model H6-HS, Eyetrack 6000).
  • To achieve this a three dimensional database of a prototypical Israeli city was built in cooperation with b.design (http://www.b-d.co.il/) , a leading provider of 3-D content. Cars, trees, billboards and various other urban elements were also designed uniquely for this environment. Using the VR-Vantage and VR-Forces different scenarios were developed to examine crossing behavior at various conditions.

Figure 1. The generic city simulated environment presented in the Dome setting (it looks a bit awkward here because its intended to be projected on a dome screen). The Field of View is: (1) Unrestricted (above); (2) Partially obscured by the road’s curvature (middle); (3) Partially obscured by parked vehicles (below).
