Our main product in the segment of winter maintenance is a mobile road weather sensor, called Road Condition Monitor RCM411, and an associated data acquisition and displaying system. The performance of RCM411 has been verified in several published third party tests and comparisons. Another product is braking Friction Meter µTEC, which is an Android phone application. Data acquisition is integrated in a single application, which records GPS information and communicates all the collected data to a server for displaying it in Mobile Road Condition Map.
RCM411 is an optical sensor based on spectral analysis. The firmware of the sensor measures the optical reflection signals and analyses the data to produce a road surface condition and friction report.
RCM411 reports the following road surface information:
RCM411 sensor highlights:
Surface temperature sensor RTS411/RTS411SA and Surface temperature and dew point sensor RTD411SA can be used as stand-alone units or as an integrated part of the Road condition monitorin system. The standalone versions include sensor heads and an enclosure with Bluetooth unit. A mobile device is used for user interface in the vehicle and for data transmission to selected servers. Mounting is easy on the metallic parts of the vehicle by using a magnetic fixture.
µTEC is an Android smartphone application, which is based on measurement of acceleration while braking a car so that the tires start to slip. µTEC has been certified for Quality Control measurements by the Finnish Transport Agency. µTEC was used as a reference when RCM411 was developed.
µTEC application was developed in collaboration with Iriba Oy.µTEC features:
