Towards Pavement Milling Specifications

Milling can be defined as a process of removing the pavement surface, and other layers, using drum-mounted carbide steel cutting bits attached to a milling machine. Pavement milling may alter the surface texture of the remaining structure, creating differences from the original surface which can

Automatic positioning of traffic management cameras on roadway incidents

Agency roadside cameras play a critical role in traffic incident management by helping dispatchers quickly identify the precise location of incidents when receiving reports from motorists with varying levels of spatial accuracy. During real-time incident dispatching, reducing the time it takes to identify the most relevant cameras and setting their view on the incident is an important opportunity to improve incident management dispatch times.
