Traffic counting is one of the most important tools for transportation engineers and planners. It provides valuable information about traffic flow in a given area, which can be used to determine whether a road needs to be expanded or if changes are needed at intersections. 

Traffic count data can also help agencies develop effective strategies to manage congestion and improve safety. Despite its importance, however, traffic counting in Sydney has always been difficult and time-consuming. Manual methods can only provide limited coverage with limited accuracy while automated sensors require extensive calibration before they are deployed on the ground. Fortunately, there is now a third option: mobile sensing technology that can provide real-time data wherever it’s needed.
