The MVMS solar speed trailer is perfect for temporary speed studies on roads perceived to have a speeding problem. The data from speed surveys can ensure site selection criteria for permanent signage are met. Speed trailers not only have a positive effect on driver behaviour and reduce speeding; they also make motorists aware of speed limits.
It is worth noting that speed trailers have a ‘novelty’ effect and should remain for a short period (around two to three weeks) in order to maximise the effect. The mobile speed trailer can then be moved to a different site and rotated between sites for maximum effectiveness. This is why a portable sign is a real benefit in influencing driver behaviour. For optimum results, the radar within the speed trailer should be set to detect and display vehicle speeds at around 100m beyond the sign.
