Vaisala says it’s time to take road weather seriously

“It is time to take road weather seriously,” is how Vaisala’s Danny Johns puts the company’s message to this week’s ITS World Congress delegates, and the wider world. While the monitoring of winter weather is well established, wind, rain and poor visibility can occur at any time of the year and have significant impacts on traffic flows and crash statistics. “We are now mapping road networks to identify weather-sensitive areas to best locate road weather stations – it doesn’t take a lot of rain or wind to

“It is time to take road weather seriously,” is how 144 Vaisala’s Danny Johns puts the company’s message to this week’s ITS World Congress delegates, and the wider world.

While the monitoring of winter weather is well established, wind, rain and poor visibility can occur at any time of the year and have significant impacts on traffic flows and crash statistics.

“We are now mapping road networks to identify weather-sensitive areas to best locate road weather stations – it doesn’t take a lot of rain or wind to cause an increase in incidents,” said Johns.

Vaisala’s RWS 200 road weather station, displayed on the company’s stand, is fitted with three lasers to measure water, ice and snow and then calculate the available grip. When the grip level falls below a pre-set level, it will either send an alert to the traffic monitoring centre or, particularly in rural locations, automatically activate variable message or speed signs.

“We have had examples of significant decreases in crashes after road weather monitoring stations have been installed,” Johns said.

    Jenoptik’s Uwe Urban looks at the advantages of ‘sensor fusion’ for the ITS sector. When considering the ideal sensing and monitoring system to enable the ITS sector to deliver improvements in mobility and road safety, for general policing security and border protection, we have to think beyond radar-base systems or laser scanners. What is needed today are solutions for detecting and tracking vehicles while recording evidence to deacide if any action is necessary. There is no sole sensor capable of

    Some developed countries are far from leading the way when it comes to making road infrastructure safe. In fact, says the Road Safety Foundation's Joanne Hill, they learn a lot from what is happening in emergent nations. A new report from the Road Safety Foundation, 'Saving Lives, Saving Money - the costs and benefits of achieving safe roads', makes some startling assertions about attitudes to road safety. Although concerned predominantly with the UK, there are some universal lessons to be learned, accordin

    Minnesota Department of Transportation (MnDOT) is working toward making the state’s roads safer, using the Canoga traffic sensing solution from Global Traffic Technologies (GTT) to warn at-risk drivers when cross-traffic is approaching. Nearly 70 per cent of fatal vehicle collisions in Minnesota, as well as other states, occur on roads in rural communities, where higher speeds, varying terrain and inconsistent sightlines can put many drivers in danger. The MnDOT initiative is part of the nationwide Towards
