Case Study:
Westcotec phone detection
warning system
Overview of the approach
One option for deterring mobile phone use by
drivers is a technology that uses the signal from an
active mobile phone to activate a warning sign of
some sort. One company which produces such a
technology is Westcotec, who completed our survey
and subsequently agreed to a Knowledge Exchange
Consultation. In the Westcotec system, an LED warning
sign that depicts the outline of a mobile phone, crossed
out in the traditional way (see right) is activated by a
vehicle occupant using a mobile phone. A sensor that
detects a phone signal is placed near the roadside,
with the flashing warning sign placed a short distance
ahead. The technology can detect if a road user is using
Bluetooth and will not activate the warning sign in such
circumstances. A range of actions can be identified by
the sensor, including calls and data retrieval.
The system is currently used as an educational tool, highlighting to drivers that they should not use their phones
while driving. The device is not currently connected with enforcement as there is not yet the capability to
distinguish between use by drivers and passengers, although this may be something that could be explored with
other technology partners in the future. In its current form, the device is therefore able to educate drivers and
passengers about the need to refrain from using a phone whilst driving, but cannot initiate any specific action
against drivers.
Mobile:Engaged contribution
Knowledge exchange
Having met the Westcotec team on several occasions, and seen the product demonstrated, a knowledge
exchange consultation (KEC) took place with two members of the team. We focussed discussion on two main
areas - future developments and anticipated challenges.
We hope that our comments are useful to forces considering purchasing similar devices in future,
