Abstract
At present, many detectors installed on both urban and interurban roads are capable of extracting information from vehicles such as speed, length or direction of traffic. However, very few sensors are currently able to communicate and exchange information with vehicles in real time. For this reason and due to the existing need for vehicle-infrastructure communication in Intelligent Transportation Systems (ITS), this paper proposes the use of Radio-Frequency-Identification cards together with the magnetic loops already in operation on the road to extract and exchange information about different vehicles through bidirectional communication. This usage will lead to many applications. Therefore, different RFID cards and their operating mode and the electrical circuits necessary for accurate system operation will be presented and analyzed.
Highlights
T HE transformation of transport is a reality
The need for greater control over vehicles is increasing considerably; this increase is why the extraction of information, identification and classification of vehicles in real time has emerged as a priority since the introduction of Intelligent Transportation Systems (ITS) [2]
Our proposal for the identification of vehicles and exchange of information is the use of RFID technology together with magnetic loops described earlier
Summary
New technologies applied to the automotive industry, big data and shared economy are changing the way people approach the world of transport These advances, which are expected to contribute to an increase in the vehicle fleet together with world population growth, will soon result in unsustainable traffic in the main cities if actions are not taken [1]. As roads cover a large proportion of the earth’s surface, especially within cities, the large number of emerging technologies are expected to turn this element, passive, into something much more productive [3]–[5] Due to their simplicity and operating mode, magnetic loops are the most used traffic sensors in ITS [6]–[8].
