INFLUENCE OF PERCENTAGE OF DETECTION ON ORIGIN - DESTINATION MATRICES CALCULATION FROM BLUETOOTH AND WIFI MAC ADDRESS COLLECTION DEVICES.

摘要

The dynamics Origin/Destination (O/D) matrices are fundamental for the management of road traffic. These matrices describe the vehicle flow between different points inside a road network for a given period of time. Currently the application of Bluetooth (BT) or wireless devices as a source of information to obtain this parameter is being widely studied. This technology does not allow the detection of 100% of the vehicles on the road, only those who have an on-board device using these technologies are detected. This paper analyses the influence of percentage of detection on the error associated with the calculated O/D matrix from BT and WIFI Media Access Control (MAC) address collection devices. For this study, the traffic simulator SUMO will be used, which will provide an initial value for the O/D matrix and will allow us to simulate different technology detection rates.
