1-36. (canceled)
A method of road traffic data collection comprising:
- providing sensor arrays of surface mounted wireless sensors on a road network;
- at least some of the arrays each comprising two or more surface mounted wireless sensors spaced along a corresponding section of road;
- receiving information from the sensors;
- and analysing received information to determine vehicle volume information with the analysis including compensating for surface mounted wireless road-based sensors having become separated from the road or are otherwise malfunctioning.
(canceled)
(canceled)
A system for traffic analysis comprising:
- sensor arrays of surface mounted wireless road-based sensors for being placed in a road network with at least some of the sensor arrays each comprising at least three surface mounted wireless road-based sensors spaced along a corresponding section of road;
- a receiver for receiving information from the sensors;
- and an analyser for analysing received information to determine vehicle speed information, the analyser being configured to compensate for surface mounted wireless road-based sensors having become separated from the road or are otherwise malfunctioning.

(canceled)
A method of adding one or more sensors to a road network comprising:
- providing arrays of surface mounted wireless sensors on a road network;
- with respect to each array, physically separating sensors in a predetermined manner along the section of road associated with the array;
- receiving information from the sensors;
- and analysing the received information to associate added sensors with arrays;
- the added sensors having been added to replace sensors that have become separated from the road or are otherwise malfunctioning.
