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.

When an issue arises which is deemed to require a technological solution governments and public-sector agencies around the world all too often tread the same sorry path.

    Meteorological organisations invest millions in super-computers to crunch data for ever-more accurate forecasts but inherent unpredictability means that other methods of alerting drivers and road authorities to fast-changing weather and highway conditions are essential. For years, static weather sensors to measure factors such as surface water, ice or high roadway temperatures have been embedded in highways to provide such data. But that is changing.

    Volvo Trucks has announced it is running successful field tests with vehicles powered by bio-DME, a fuel that can be produced cost- and energy-efficiently from biomass. Since last autumn, ten specially adapted Volvo trucks have been operating on Swedish roads using the fuel which reduces carbon emissions by 95 per cent compared with conventional diesel. The field tests have now reached the halfway point and the results so far have both met, and exceeded, expectations.
