Estação meteorológica rodoviária integrada para monitoramento de rodovias

JW-TWS series is a compact, multi-parameter monitoring instrument designed for highways, expressways, national roads, bridges, and urban traffic infrastructure.

It combines selected measurements of road visibility, pavement condition, road surface temperature, wind speed, wind direction, air temperature, humidity, and atmospheric pressure into an integrated monitoring system.

Four sensor configurations are available to accommodate different road monitoring requirements. Optional 4G communication, Bluetooth connectivity, and camera equipment provide additional deployment flexibility.

The integrated design reduces the need for multiple independent sensor housings and is particularly suitable for distributed monitoring points along highways.

1. What Is an Integrated Road Weather Station?

An integrated road weather station is a roadside monitoring instrument that combines meteorological observations with traffic-related environmental measurements.

Unlike a conventional weather station, it can include parameters directly related to road safety, such as pavement condition, road temperature, and atmospheric visibility.

The system helps road operators identify changing environmental conditions along road corridors.

Os objetivos típicos de monitoramento incluem:

• Low visibility caused by fog or haze
• Road surface icing
• Snow-covered pavement
• Acúmulo de água
• Strong winds on exposed roads
• Alterações de temperatura e umidade
• Rainfall and weather-related road risks

The compact design is suitable for installing multiple monitoring points along highways and other road networks.

2. Especificações Técnicas

The following specifications are based on the available sensor configurations.

Not all parameters are available in every model. Please refer to the configuration comparison below.

3. Integrated Road Weather Station Model Comparison

Four sensor configurations are designed for different monitoring priorities.

TWS-A — Visibility and Pavement Monitoring

Designed for applications requiring road visibility, road condition, and pavement temperature measurements.

TWS-B — Visibility and Meteorological Monitoring

Combines visibility with wind speed, wind direction, air temperature, humidity, and atmospheric pressure.

TWS-C — Pavement and Meteorological Monitoring

Combines road surface condition and temperature with conventional meteorological parameters, without standard visibility measurement.

TWS-D — Comprehensive Road Weather Monitoring

Combines visibility, pavement monitoring, meteorological parameters, and rainfall measurement.

The appropriate configuration depends on the monitored road section and project requirements.

4. Road Visibility Monitoring

Visibility monitoring is important for roads affected by fog, haze, rain, and snow.

The integrated station offers visibility measurement from 10 to 6,000 meters in configurations equipped with the visibility module.

Road visibility measurements can support:

• Fog-prone highway monitoring
• Low-visibility risk assessment
• Road environmental observations
• Traffic management decision-making

For applications requiring a dedicated instrument with a different measuring range, explore the Visibility Sensor 10km RS485 Modbus.

5. Road Surface Condition and Icing Monitoring

Road surface condition is an important parameter for winter road management.

The integrated station can identify four surface conditions:

• Pavimento seco
• Water-covered pavement
• Icy pavement
• Snow-covered pavement

The road surface temperature measurement range is -40°C to +80°C.

Combining surface condition and temperature provides useful information for assessing changing pavement conditions.

Bridge Deck Icing

Bridge decks can cool differently from surrounding ground-supported roads.

Monitoring road surface temperature and ice conditions can help maintenance teams identify sections requiring inspection.

Winter Road Maintenance

Road surface observations help operators understand when moisture, snow, or ice may affect road conditions.

For dedicated pavement analysis, see the Sensor de condição da superfície da estrada para segurança rodoviária.

6. Meteorological Monitoring for Traffic Applications

Depending on the configuration, the station can measure:

Velocidade e direção do vento

Wind measurements provide environmental information for exposed highways, elevated roads, and bridges.

Temperatura e umidade do ar

These parameters help describe atmospheric conditions associated with fog, condensation, and freezing weather.

Pressão atmosférica

Pressure measurement supports local weather observations and environmental analysis.

Rainfall and Precipitation Classification

The appropriate configurations support rainfall monitoring and precipitation intensity classification.

Optional snowfall classification is available for selected configurations.

7. Aplicações típicas

7.1 Highway and Expressway Monitoring

Compact road weather stations can be deployed at selected highway locations to collect local environmental data.

7.2 National and Provincial Roads

Distributed monitoring points can help road authorities assess weather differences across long road corridors.

7.3 River Bridges

Bridge installations can monitor selected combinations of wind, air temperature, road surface temperature, and pavement condition.

7.4 Urban Arterial Roads

The integrated design is suitable for locations where compact equipment and convenient installation are important.

7.5 Winter Road Monitoring

Road surface temperature and condition measurements support the assessment of ice and snow on traffic infrastructure.

8. Optional Communication and Monitoring Functions

The integrated road weather station offers optional communication functions for different deployment requirements.

Comunicação 4G

Optional 4G communication can support wireless transmission of monitoring data where appropriate network infrastructure is available.

Bluetooth

Optional Bluetooth communication provides an additional connectivity choice.

Câmera

An optional camera can complement measurement data with visual information from the monitored location.

Actual communication interfaces, protocols, data acquisition equipment, and platform integration should be confirmed for the selected configuration.

For projects requiring a complete modular roadside monitoring system, refer to the Estação meteorológica rodoviária para monitoramento da segurança nas rodovias.

9. How to Select the Right Configuration

Consider the following requirements:

Visibility monitoring: Select a configuration with the visibility measurement function.

Pavement condition: Choose a model with road surface status and temperature monitoring.

Wind exposure: Include wind speed and direction measurements for bridges and exposed roads.

Rainfall measurement: Select the configuration supporting the required rainfall function.

Optional environmental parameters: Confirm whether PM2.5/PM10, radiation, illuminance, or noise measurements are needed.

Remote communication: Evaluate available 4G coverage and project data-transmission requirements.

For large monitoring networks, sensor selection should consider the local climate, road characteristics, installation environment, and required monitoring parameters.
