Newswise — Professor Avi Polus of the Civil and Environmental Engineering Department at the Technion-Israel Institute of Technology is an expert on the causes of -- and possible solutions for -- highway traffic problems.

Main areas of his research include:- operational aspects of traffic, highway traffic flow and breakdown phenomena- how factors like inappropriate highway design can cause traffic flow breakdowns- major safety issues presented by inconsistent road design- impatience of drivers while passing as a serious safety issue

In one recent study, Professor Polus showed that the infrastructure causes about 45-50% of crashes on two-lane roads. This goes against the commonly held notion that such accidents are primarily caused by driver error.
