Imagine having the best system but with no system maintenance cost. Imagine Vaisala’s latest Wx Horizon Premium, a weather hazard impact portal. It delivers insights to current and future road conditions but is sold as a subscription service meaning there are no ongoing maintenance costs or large upfront investments. Wx Horizon allows road maintenance organisations to prepare for upcoming storms with high-quality pavement and atmospheric forecasts. To deliver this critical information and keep it relevant for use specifically in transportation, the system fuses measurements with industry-leading weather forecasting and road weather models.
At the heart of this service is Vaisala’s Ground Cast Sensor. It measures road surface temperature and the amount of residual treatment material, providing highway maintenance teams with reference grade observations and location-specific forecasts.
Importantly, it has multi-level road temperature measurement, from ground level as well as 6cm and 30cm below road surface. Road surface temperature accuracy is ±0.2C° This is specifically designed to improve pavement forecasts and helps proactively keep roads safe by targeting treatments and validating effectiveness in real time.
