Abstract: A real time information system provides real time comprehensive information to drivers on roads. It has short-interval units for mounting on a roadside barrier at intervals of 100 m and lower-density master control units at 1 km separations with more comprehensive displays. The short-interval units communicate with a master unit in a local area group. Local sensing of weather and traffic conditions at the master control unit allows advance warnings to drivers with a fast response time in an autonomous manner. The short-interval units have a saddle frame for fitting to the top of a central reservation barrier to allow low-level simple display of LED colour arrangements in a coordinated linear pattern when viewed in sequence by a driver. A subset of the short-interval saddle units, such as every tenth one may additionally have a display screen.
