Abstract
The use of newly emerging sensor technologies in traditional roadway systems can provide real-time traffic services to drivers through Telematics and Intelligent Transport Systems (ITSs). This paper introduces a smart roadside system that utilizes various sensors for driver assistance and traffic safety warnings. This paper shows two road application models for a smart roadside system and sensors: a red-light violation warning system for signalized intersections, and a speed advisory system for highways. Evaluation results for the two services are then shown using a micro-simulation method. In the given real-time applications for drivers, the framework and certain algorithms produce a very efficient solution with respect to the roadway type features and sensor type use.
Highlights
Telematics are defined as in-vehicle systems that offer active safety and infotainment services as well as location and traffic information via wireless communication technologies
We deal with Telematics/Intelligent Transport Systems (ITSs) service based on new IT technologies using a smart roadside server on a smart road, and we focus in particular on the system architecture and components, including service processing algorithm and issues
An evaluation of in- and out-of-vehicle traveller information systems is well-suited to virtual testing, which has an advantage over roadway studies, because it allows an examination of parameters of interest in difficult and critical driving situations without subjecting drivers to unnecessary risks
Summary
Telematics are defined as in-vehicle systems that offer active safety and infotainment services as well as location and traffic information via wireless communication technologies. “cooperative” indicates systems that cooperate on two levels: (1) direct communication and the exchange of valuable information between entities; and (2) dynamic interaction amongst roadway users and transport infrastructure, which can provide win-win benefits for both drivers and roadway operators. Through the IntelliDrive, CVIS, and SMART highway projects, researches regarding infrastructure-based sensors and OBD II-based vehicle sensors for safe driving have been ongoing. These infrastructure, in-vehicle, and smart roadside server sensors can enhance driver capability and perception. We deal with Telematics/ITS service based on new IT technologies using a smart roadside server on a smart road, and we focus in particular on the system architecture and components, including service processing algorithm and issues. Offer some concluding remarks regarding the research described in this paper, and provide some perspectives on future work
