BS EN 15518-1:2011EN 15518-1:2011 (E) 4 Introduction Road Weather Information Systems (RWIS) are complex structures used for road maintenance decision support, which feature as a ru
18、le the following components: meteorological sensors and instruments, transmission technology, computer systems for processing, representation and storing of information, road weather forecasts and alarms, in relation to traffic control and traffic information systems and more. With a set terminology
19、 for the components and the meteorological expressions, an attempt is made to counteract a diversity of terms and designations for identical phenomena. BS EN 15518-1:2011EN 15518-1:2011 (E) 5 1 Scope This European Standard defines the “Road Weather Information Systems” (RWIS) concept for public road
20、s and traffic surfaces. This standard applies to the acquisition of data on weather-related road and environment conditions as well as their forecast. This information is typically used for road maintenance and can serve other systems like traffic management, road users information, data models, etc

22、 definition and components 3.1 Description of concept A Road Weather Information System (RWIS) can be defined as a combination of technologies that uses historic and current climatological data to develop road and weather information (for example, nowcasts and forecasts) to aid in roadway-related de
23、cision making. The three main elements of RWIS are: environmental sensor tools (fixed or mobile) to collect data; models and other advanced processing systems to develop forecasts and tailor the information into an easily understood format; dissemination platforms on which to display the tailored in
24、formation.BS EN 15518-1:2011EN 15518-1:2011 (E) 6 Figure 1 Components of a RWIS systemBS EN 15518-1:2011EN 15518-1:2011 (E) 7 3.2 Description of components 3.2.1 Road weather station Road weather stations are the components of RWIS which provide the environmental data. Many types of data can be coll
25、ected, the most common being (non exhaustive list): weather air temperature, amount and type of precipitation, visibility, dew point, relative humidity, and wind speed and direction, and cloud cover; road condition pavement temperature, subsurface temperature, surface condition (dry, wet or frozen),
26、 amount of de-icing chemical on the roadway, and freezing point of the road surface. These data are collected by sensors placed at the roadside or in the roadway itself. Remote processing units (RPUs) placed along the roadway contain some or all of the road and weather sensors. In some cases, the pa
27、vement sensors are located apart from the RPU, with several pavement sensors capable of being linked to one RPU. However, these RPUs are usually connected to a central server for further data processing. 3.2.2 Weather observation and forecast The raw data are used directly or in coordination with a
28、service provider to prepare nowcasts or forecasts. Both can be used to predict site-specific weather and pavement conditions and to support maintenance operations. 3.2.3 Mobile or portable data acquisition systems Mobile data acquisition systems monitor atmospheric parameters and road conditions at
29、the time and position of the mobile. Portable data acquisition systems monitor atmospheric parameters and road conditions at a given time and position. These data are complementary to stationary road weather stations. 3.2.4 Traffic data The traffic volume, typology, characteristics could be taken in
30、to account for the analysis of RWIS data and models. On the other hand, the analysis of RWIS raw or processed data could be included in road management tools. 3.2.5 Cameras The analysis of raw or processed images, depending on the spectra, could be included in road management tools, such as monitori
31、ng road surface condition (snow, de-icing application control, etc.), or traffic volume. 3.2.6 PC, servers, data concentrators Local and/or central processing units ensure collection, storage, processing and distribution of the data. Several communication mechanisms can be used for information colle
32、ction and distribution, like Internet, Intranet, satellite, dial-up lines, etc. 3.2.7 Models, algorithms The models and algorithms aggregate and process data from different sources, according to the specifications of the final user (road managers, forecasters, and road users).

33、5518-1:2011 (E) 8 3.2.8 Man machine interface The man machine interface consists of visualization and operation tools, which should be adapted to the needs of the final user (road managers, forecasters, and road users). 3.2.9 Data transfer Data transfer can use various media, like phone lines, radio
34、 signals, etc. The characteristics of the data transfer should not impair the further use of the data provided by the different sensors. 3.2.10 Communication to other systems Pertinent RWIS information can be transmitted to other systems in order to improve traffic security and fluidity, like variab
35、le message signs, on-board navigation systems, etc. BS EN 15518-1:2011EN 15518-1:2011 (E) 9 Bibliography EN 15144, Winter maintenance equipment Terminology Terms for winter maintenance This page deliberately left blankThis page deliberately left blankBSI is the independent national body responsible
