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.

“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.

    New trials show Bluetooth and Wi-Fi signals can be reliably used for measuring travel times and at a lower cost than an ANPR system, but which is the better proposition depends on many factors. Measuring travel times has traditionally relied automatic number plate (or licence plate) recognition (ANPR/ALPR) cameras capturing the progress of vehicles travelling along a pre-defined route. Such systems also have the benefit of being able to count passing traffic and have become a vital tool in dealing with c

Wilmington and Newark (pronounced new-ark) are two vastly different cities that sit on opposite ends of Delaware. Newark is a sleepy university town of roughly 30,000 residents abutting the state’s western border with Maryland and Pennsylvania, and often gets confused with its larger namesake in New Jersey.

    EarthSense is working in the UK with Coventry City Council to divert traffic away from heavily congested roads and pollution hotspots. EarthSense’s air quality sensors are located in areas of the city where levels of nitrogen dioxide have been identified as high; particularly along the A4600 route at Walsgrave Road – a major link in and out of Coventry. When pollution levels are breached, the sensors send alerts to the urban traffic management centre where they trigger messaging on variable message s
