Traffic and Safety

Using in-vehicle warnings to reduce risky driver behavior at work zones

We propose to:

- Identify the work zone related safety problem(s) by analyzing associated crash causal factors, types and locations relative to the work zone approach direction or other work zone characteristics.

- Identify current problems that may be occurring as a result of limitations of static signage and/or of management of static signage.

- Focus on solving “real” problems that consider actual field situations and the constraints associated with personnel that usually deploy assets at work zones.

- Design a readily deployable methodology for driver warning that reduces risky behavior around the work zone, which captures the driver attention and is compelling.

- Consider methods NOT associated with common automated speed enforcement approaches.

- Define our tasks in such a way that we can move forward in steps and develop approaches in measurable stages.

    This would be very worthwhile research in a couple of different ways:

    - we currently only have signs in the tool box, which requires that the drivers are paying attention and visually looking in an appropriate place; by adding auditory warnings, we are engaging a second sense to grab the driver's attention

    - human factor research will help us determine the most effective way to engage the driver's attention
