Disclosed are systems and methods for estimating road traffic in a road segment at a given time. The system comprising: a central server; and at least one of one or more mobile communication units installed in a vehicle passing the road segment at the given time, wherein each of the mobile communication unit is capable of sending a plurality of mobile spot values to the central server, and one or more fixed communication units installed for detecting wireless enabled objects in vehicles passing the road segment at the given time, wherein each of the fixed communication unit is capable of sending a plurality of detected spot values to the central server. The central server is capable of processing the at least one of the plurality of mobile spot values and the plurality of detected spot values to estimate road traffic in the road segment at the given time.

Methods and systems for estimating road traffic

Disclosed are map matching methods and system for tracking and determining an improved position of a reference asset. The method comprising: receiving at least one global navigation satellite system (GNSS) current position probe from the reference asset; requesting and receiving information from a geographical information system (GIS) unit on a plurality of probable road network segments on which the at least one GNSS current position probe is capable of being snapped; computing a weighted cost function for each of the probable road network segments; and snapping and information fusing the current position of the reference asset with a selected road network segment having the minimum weighted cost function out of the probable road network segments.
