This paper suggests a decision support system for vehicle drivers, accessible via mobile phone. Concept behind the system is to help drivers to schedule their activities, best utilizing their time along the way, minimizing the impacts of traffic. This is in contrast to existing approaches focused on controlling traffic in highways. Vehicle is continuously tracked along the journey and information...
This paper presents vehicle control system for automatic valet parking with infrastructure sensors. First, we describe the automatic valet parking service system. In the service, vehicle moves autonomously based on sensing data generated by infrastructure sensors. Second, we implement vehicle control system for automatic valet parking. We design hardware and software components focusing on minimizing...
In many countries, various in-vehicle Telematics systems are already available, while new systems are being currently designed. This paper introduces a smart roadside server for driver assistance and traffic safety warning. In recent world wide projects, roadside equipment is used for wider applications and becomes a server with more intelligent functions. This paper introduces a concept and framework...
It is useful to share location-dependent data items generated by vehicles such as a picture image of a traffic accident and the traffic condition around an intersection in vehicular ad hoc networks (VANETs) for improving the driver safety and comfort. In VANETs, due to the mobility of vehicles, it is difficult to reliably access data on other nodes. To improve the accessibility of data from a vehicle...
This paper describes the experimental design for the field tests of safety applications within the scope of Networked Traveler Project currently being conducted in California, which is part of the US Department of Transportation (USDOT) and California DOT-sponsored Safe-Trip 21 Initiative. The safety applications are designed to provide drivers with alerts of situational awareness in highway driving...
With the maturation of wireless networks technologies, Telematics service is becoming a new rising and popular network service and application. In this paper, a centralized vehicular Peer-to-Peer Telematics (C-VP2P) service discovery platform is proposed to provide efficient and feasible service discovery. This paper focuses on the issues of developing a Telematics service platform over the vehicular...
One opportunity to manage the increase of freight transportation and to optimize utilization of motorway capacities is the concept of truck platoons. With the aid of Advanced Driver Assistance Systems, trucks are electronically coupled keeping very short gaps (approx. 10 meters) to form truck platoons on motorways. This contributes to optimization of traffic flow and reduction of fuel consumption...
The driver assistance system is more and more widely used with the development of automobile industry. The driver assistance system based on pervasive computing integrates the function of computing, communicating and sensing, which can assure the driving safety and prejudging the traffic emergency by sharing the information among vehicles of the same district. The structure and working principle of...
In this paper, a brief introduction of automated truck platoons on motorways is given. It includes a description, of the scenario ??platoons organized by the driver??, the system architecture of the platoon system and a description of the software architecture for a driver information system. The results of the accomplished system and acceptance tests of the platoon system in the truck driving simulator...
A prototype of pedestrian-to-vehicle communication system which uses 3G wireless network in combination with wireless LAN was developed by using cellular phones and car navigation systems. The system can exchange the information between pedestrians and vehicles, indicate the location of the ones that have an accident risk, and call for attention by employing the developed algorithm for estimating...
For the realization of a safe road traffic environment a wireless communication system which makes an information network between pedestrians and vehicles has been needed. A prototype of pedestrian-to-vehicle communication system was developed by using a cellular phone and a car navigation system equipped with GPS and wireless communication function. By interoperation of 3G wireless network and wireless...
