Easier quality control of winter road maintenance

Tyre/Road surface friction is widely used as a method of controlling the quality of winter road maintenance. Friction is the only well defined quantity to describe the grip of car tyres to the road surface. On a normal dry road surface friction varies typically between 0.80 0.10 in a vehicle with standard type of tyres. If there is hard ice on the road, friction experienced by all vehicles drops dramatically regardless of the quality of the tyres on the vehicle - on a thick layer of ice even to the level of 0.20.

There are several issues to be dealt with when measuring friction and using it as a measure of quality in modern winter road maintenance:

measuring road surface friction, collecting and transmitting measured data in large scale has not been possible in an economical way

due to varying measurement methods it has been difficult to implement a uniform system to measure the level of performance by the contractors

in changing weather conditions it has not been possible to measure, collect and deliver friction data fast enough

setting up large scale advisory systems for motorists based on road surface friction has not succeeded due to measurement costs

Mobile technology has revolutionised the ways we communicate, send and receive data and locate ourselves. That same technology has been put to work to make measuring friction faster, easier and more economical. It has made it possible to store, send and locate measurement data on a map.

Todays modern winter road maintenance faces multiple challenges:

economical and environmental

road safety and traffic management

How to optimise the use of staff, vehicles, de-icing material and improve best practices with measured data? How to produce a satisfactory winter road grip and how to measure it in an economical way? How to set up a warning system and improve the chances of obtaining safer conditions sooner?

The roads form the backbone of our society. Keeping the traffic flowing freely and safely is vital to our economy. Weather influences the road conditions and safety to a great extent. In many cases bad road conditions such as icy or snowy road surfaces are a contributing factor to accidents and delays.

Road maintenance, especially winter road maintenance plays a major role in traffic flow and safety.

TEC is a solution for measuring road surface friction utilizing the 3D-accelerometer of a mobile phone. It is not fixed to a specific vehicle and it can be used in any type of vehicle.

TEC is easy and fast to calibrate. It gives correct measurement independently of the vehicle and its brake system. TEC enables continuous measurement and storing of the measured data.

TEC can be installed on several types of mobile phones with 3D-accelerometer

TEC

runs on mobile phones using S60, Symbian^3 and Android platforms

fast and easy calibration

stores coordinates for accurate location of measurement data

Easier quality control of winter road maintenance

Mobile Friction measurement service; a realtime system of collecting and displaying road friction measurement data. MMS collects measured data, classifies it into pre-definied slipperiness classes and displays the data on a digital map.

It is also possible to import camera data and other data to be displayed on the same map. Even weather forecasts and other information can be combined with friction data in MMS.

and mobile friction measurement systemTEC is a mobile friction solution and MMS is a realtime service of collecting and displaying friction measurement data.
