The Smart Rest Area system developed by Spatial Vision for Roads and Maritime Services and Transport for New South Wales, compromises an in-vehicle Android app running on a Nexus 7 tablet, teamed with a cloud-hosted management system. This trial was started in late May of 2014.
The Nexus 7 tablet, installed on the truck’s dashboard, reads the trucks current location and direction and sends this to the management system via the mobile phone network. The central server uses spatial technology to determine which road the truck is on, which direction it’s travelling and which rest areas are ahead on the road.
It calculates the distance to each rest area, the approximate travel time and queries the vacancy measurement system to determine how much parking space is currently available. This information is returned to the truck, along with details of what facilities are available at each rest area, such as water, toilets and bins.
Spatial Vision developed the system using mainly open source technologies, with the NSW roads, rest area and speed limit data being processed and loaded into a PostGIS database. The management system provides a dashboard to RMS administrators and registered users, which has the ability to update the rest area database and view reports showing use of the system, including map reports.
