Currently the most common practices to try to get drivers to
stay within reasonable prescribed speed limits include:
- Marking crosswalks: At cross roads and at certain points the authorities do mark the roads with stripes indicating that pedestrians may cross safely. However, studies have shown that in the USA context, drivers disregard such stripes and zoom through with utmost disregard for pedestrians who may be crossing at these zebra lines.
- Stop signs are equally ineffective because they are largely ignored.
- Speed bumps are slightly more effective but it may not be practically possible to place them at all points. Bumps can impede emergency services vehicles.
The more modern, effective, safe and effective way to get
drivers to slow down is a large, well lit LED speed display board that
displays the vehicle’s speed and also indicates the safe speed limit for that
specific zone. Now becoming highly popular and introduced into US by
Photonplay.com, a global enterprise, these driver feedback signs are
based on radar technologies. A typical speed radar sign works on radar.
Radio frequency waves emitted by the unit bounce off the vehicle and measure
its speed. This vehicle activated sign is aimed at the incoming vehicle
within a specific zone and it works in conjunction with a computerized unit
that allows authorities to set the safe speed limit and other parameters as
well as capture data for analytic.
Available in various types such as street model, models for
work zones, highway models and portable series, the radar speed displays have
numerals ranging in size from 9
inches to 24 inches . Rugged for US conditions
Photon radar feedback sign units work under widely varying climatic conditions
and give uninterrupted services with the least maintenance. Easy to set up and
use, even by untrained operators, the traffic calming signs are the next
generation, modern way of getting drivers to drive sensibly. The world is
changing over to radar speed display boards and it will not be long before
their widespread deployment in US will see a reduction in traffic accidents as well as moralities.
