Clearview Traffic has launched the M210 solar-powered logging stud, which offers an alternative to the traditional single loop site, by providing count information in a simple, self contained unit. In situations where there is a requirement to accurately count and classify vehicles traveling on a road, traffic planners often need more data than is currently available. If roads within an area have no counting systems installed, long term trends become ‘invisible’ to engineers. The only solution to this problem is to install a network of loop based traffic counters, but this is often not economically practical due to the costs of installing and maintaining these devices.
The new M210 solar-powered logging stud combines several technologies, including solar power, radio communications and magnetometer-based vehicle detection. The self contained traffic counter is installed into a 13cm diameter hole in the centre of the lane. Once installed, it can count any passing vehicles, recording data in one minute intervals and storing it within the unit. An integrated solar panel provides power to a high-efficiency rechargeable battery that will ensure continuous operation for many years without the need for any form of routine maintenance.
In order to collect the data from the device, a specially designed radio dongle can be plugged into a USB port to wirelessly communicate to the M210. Data can then be collected using a simple download application. As the range of the wireless communications will work up to 10m away, this can be achieved both simply and safely from the roadside. The stud’s simple construction allows fast and simple installation, as there is no requirement to install loops, cabinets or other roadside furniture, with significant savings in both costs and traffic disruption.
As the device uses a magnetometer to detect vehicles, it is immune from problems associated with damage to loops, including road degradation, utility works or road repairs. The M210 is also unobtrusive and is less likely to sustain damage from road users, which is common with other types of beside-the-road counter. Due to its large integrated memory capacity, users can experience increased efficiencies with minimal maintenance and less data collection trips required. The use of renewable energy sources helps to provide a green solution, which is a positive step for many authorities who may be looking to reduce their carbon footprint. Peter Cattell, product manager at Clearview Traffic says, “The new Logging Stud provides traffic managers with a cost effective way to run multiple counts in fixed locations, offering an alternative to installing single loop sites which can be expensive; requiring trenching and ducting, and disruptive to traffic flows.”
