Vaisala Road Weather Navigator is designed for customers using their own data collection server(s). This allows for full control of data collection, server maintenance, upgrades, communications, etc. Navigator software has a large storage capacity for data and is ideal for large RWIS networks. It is capable of displaying any number of RWIS sensor measurements - from current pavement status to streaming video to traffic speeds or air quality. Navigator is user-friendly and allows you to customize data views, such as adding your own map images or selecting which data parameters appear to different user groups (an administrator may look at additional data such as traffic conditions, while day-to-day operations personnel view a standard set of data). One of the most powerful aspects of the Vaisala Road Weather Navigator is the alarming and alerting capabilities. The warning is displayed directly in the software and is also emailed to selected personnel in your organization. The defining aspect is that you choose which weather parameters you want to be notified about – whether it is when the pavement temperature falls below freezing or simply when precipitation begins – you choose the level of monitoring.
