RADARSTATUS MAP

The latest fourth generation of METIS brings many useful features. Great emphasis is placed on the status map, where a variety of meteorological data can be displayed to support the spatial weather perception. Additions are a clearly arranged dashboard and a real-time animation of cloud cover and precipitation. Another strong feature is the “performance“ module that enables online monitoring of winter maintenance vehicles and efficient winter maintenance reporting and evaluation.

METISMETIS is a unique software system for monitoring road weather data and information focusing on the current and future situation on the roads. METIS provides a comprehensive overview of the weather in real time.

SSWM is a complex system for road condition and temperature prediction. It uses a sophisticated prediction core and a unique GIS approach to provide the forecast for each and every road stretch enabling selective salting. Moreover, SSWM provides a thorough treatment recommendation including the salt dosage for each maintenance area.

CROSS acquired exclusive partnership and representation of MetSense company for installation and operation of the very new and promising hi-tech road weather camera called 2DRoad.

This innovative technology offers markable change of road pavement sensing in next few years, because it brings a completely new view of the road surface condition in two dimensions.

2DRoadREVOLUTIONARY INNOVATION

The camera can sense the whole profile of the road, an area up to 6 x 6 m wide. In comparison with other non-invasive sensors which measure

Option to set the size of the scanned area according to particular needs

Without the need of a mechanical intervention to the road

Clear visual outputs

a single point (or small area) on the road, the 2DRoad measures 4096 points simultaneously. Each of the points can determine whether the place is dry, wet or covered in snow or ice. The road surface temperature is measured at one point approximately in the centre of the scanned area.

Systematic installation of a road weather station network in the Czech Republic began in the mid-nineties. Currently, the Czech road network is equipped with more than 600 units. All of them are integrated in the METIS system.

The total number of stations is constantly growing and the network allows us to monitor more than 60,000 km of roads in the whole Czech Republic.

METIS 4 and related modules (SSWM, WMi) are used by the national road authority and a number of other entities (cities and regional authorities) and private companies (e.g. technical services).
