Abstract:

In variable speed limit (VSL) zones, the speed

limit changes in response to traffic congestion,

adverse weather, or road conditions. VSL zones are

often highly automated and have been employed

successfully in several U.S. and European

locations. Dynamic signs display the current speed

limit, adjusted according to a specific set of rules

and based on data transmitted from highway

sensors. Sometimes, VSL signs are paired with

signs that inform drivers about road conditions or

minimum speed. Ideally, approaching traffic will

slow down and pass through the problem area at a

slower but more consistent speed, reducing stopand-

go traffic. This also reduces the probability of

an accident by giving drivers more time to react

to changing road conditions and helping them

avoid the need to brake sharply as they approach

congestion.
