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).
