Intrusion warning improves workzone safety

Transpo Industries launched a unique concept in work zone intrusion protection last year. The SonoBlaster impact-activated safety device warns both roadway workers and errant vehicles simultaneously. When impacted, the unit's built-in CO2-powered horn blasts loudly (125 dB) for 15 seconds, signalling crews that their work zone has been violated. This provides critical reaction time to move out of harm's way. The company says there are also resultant safety benefits for the driver, who may be able to take ev

Transpo Industries launched a unique concept in work zone intrusion protection last year.

The SonoBlaster impact-activated safety device warns both roadway workers and errant vehicles simultaneously. When impacted, the unit's built-in CO2-powered horn blasts loudly (125 dB) for 15 seconds, signalling crews that their work zone has been violated. This provides critical reaction time to move out of harm's way. The company says there are also resultant safety benefits for the driver, who may be able to take evasive action.

 Since its launch, Transpo says that as a result of customer feedback from deployments in over 27 US states as well as seven different countries, a stackable cone bracket has been added to the device so the Sonoblaster can remain mounted and ready to use on a work truck.

The idea of every traffic light turning green as you approach it has long been a dream for many an urban driver – and none more so than those driving heavy goods vehicles (HGVs), which are slow and difficult to bring to a halt and then accelerate back to normal travel speed. But that dream has become a reality for some drivers in a small number of cities around Europe in the las

The Jane Addams Memorial Tollway in Illinois, US is well on the way towards becoming a ‘smart traffic corridor’, taking full advantage of active traffic management (ATM or ‘managed lanes’) technology that originated in Europe. It is one of the first American toll roads to do so; preliminary work began in 2014 and will continue through to 2016.
