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.

    Colin Sowman gets the global view on how ITS has shaped the way we travel today and what will shape the way we travel tomorrow. Over the past two decades the scope and spread of intelligent transport systems has grown and diversified to encompass all modes of travel while at the same time integrating and consolidating. Two decades ago the idea of detecting cyclists or pedestrians may have been considered impossible and why would you want to do that anyway? Today cyclists can account for a significant propor

    Currently deployed technology is being used to detect motorists ignoring the ‘red-X’ signs that indicate the lane is closed, as Colin Sowman hears. With an increasing network of ‘Smart Motorways’ - all-lane running or the opening of hard shoulders during times of congestion - Highways England (HE) has identified a growing problem with ‘red-X’ compliance. The ‘red-X’ sign signifies a closed lane or lanes and used to provide a safer area for stranded motorists, emergency workers or road maintenance crews and

    In Sweden, marketing company DDB Stockholm employed a mock speed camera as part of a promotional campaign for automotive manufacturer Volkswagen. The result was worldwide online interest and promotion of the debate over excessive speed to the national level. A developing trend in traffic management policy is to look at how to induce road users to modify their behaviour by incentivising change rather than forcing it through the application of penalties. There have been several studies conducted into this; an
