Smart Roadside System for Driver Assistance and Safety Warnings: Framework and Applications

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 of smart roadside server in various road systems using Telematics system. We suggest two service and application models in signalized intersection and SMART highway. This system models provide a vehicular safety service to a vehicle terminal of a vehicle located on a road within a service area from a smart roadside server. The smart roadside server is useful for driver assistance and warning by Telematics devices.

Service Bundle Providing System in Open Telematics Environment

As telematics technology has rapidly developed, many kinds of telematics service applications and terminals are provided to cars. Telematics service users however can not use various services because service providers provide services using their own terminal in which the service applications are built and do not provide methods to download and install new applications. It means that to use many kinds of services, users have to buy a lot of terminals. In order to solve this problem, we suggest telematics service bundle providing system which enables service providers to register their service applications and enable service users to search, download and install service applications.

Future Automotive Insurance System based on Telematics Technology

With the proliferation of vehicles and advancement of information technology, the technology of telematics, which provides valuable services to people by collecting and analyzing the information from drivers, vehicles and Telematics environments (e.g. traffic information, road condition, weather information, etc.), has been a hot research area in IT and automotive recently. There are needs for telematics makes more profitable. Telematics based insurance services could be one possible business model. In this paper, we have investigated trends of telematics based insurance services in the industry and discussed required technologies for telematics based insurance services. Finally, we summarized the framework for insurance telematics which we had developed.

Short paper: Study of driver workload-based smartphone control service

When any distracted driving of the driver is concerned, use of smartphones and navigation systems while driving are major causes for traffic accidents. However, in a situation where navigation systems are commonly installed and smartphones are commonly used within vehicles, it is better to implement technologies that control the use of smartphones in high-risk situations and allow brief periods of use otherwise, rather than ban the use of smartphones altogether while driving. This study introduces the DWMS (Driver Workload Management System) and proposes service that controls the use of smartphones according to drivers workloads. The DWMS periodically monitors the drivers behaviors and smartphone usages in order to calculate driving workload. When the calculated workload exceeds the threshold value, the driver is deemed to be overburdened and all incoming calls and SMS (Short Message Service) is blocked. The service will then make a notification when this status is relieved. In addition, at the end of driving, the DWMS will provide a summary of the information on how the driver drives, workload, and behaviors taken as a text message to the drivers smartphone. The result of this study can increase both driving safety and convenience for drivers.

Driving characteristics analysis of young and middle-aged drivers

From the statistics about rental car accidents, traffic accident death by drunken driving, speeding, and centerline invasion occurs frequently to the twenties drivers compared with the other age groups. Specially, speeding is a dangerous driving behavior. In this paper, we analyzed driving characteristics of young and middle-aged drivers using FOT (Field of Test) data which was collected on the real urban, local road and highway. We performed independent samples t-test to know the difference of driving time, average speed and maximum speed dependent on ages and gender. We found that young male drivers drove more fast than middle-aged drivers on the local roads and highways. Also, we performed ANOVA analysis to know the speeding characteristics of drivers. The speeding time of young driver is longer than that of middle-aged driver on the local road and highway. The results of this study can be utilized in the device to limit the speed through monitoring the running speed of the driver. It can be derived indirectly safe driving services to reflect the speed factor of driver in the driving insurance fee calculation method.

Postal delivery area Management System

One of the important issues in postal business in Korea is to distribute the delivery areas equally and to calculate optimal delivery routes to reduce delivery cost. However, it is difficult problems because postal managers distribute the delivery areas by heuristic methods and postmen have simply decided optimal delivery routes b y the ir experiences. Also raw data of delivery activity log have not been collected systematically and have not been managed. Postal system could not calculate optimal solution due to small or absence of daily delivery log data. This paper describes the development of a system designed to create delivery area using building information and delivery route optimization: Postal delivery area Management System (PMS). Using a map data and openlayers library, the PMS provide function of creating delivery areas by selecting zone code and drawing polygon on the map. Also the PMS is able to calculate the shortest distance routes using the list of daily delivery addresses.

A real-time tracking system of postal motorcyclists

National postal services have developed tracking-enabled delivery management systems to provide improved service and more effective management of deliveries. This paper presents a real-time tracking system of postal motorcyclists that we developed with the support of funds from Korea Post. The system tracks movement of postmen during all their working hours and visualizes their delivery routes in real-time. To improve safety, the system also extracts a postmans driving patterns to identify any elements of risky driving.

Request Based Telematics Contents Providing System using DMB

This paper describes a system for providing the telematics contents through DMB, according to the requests which are demanded by users. This paper includes the structure of the system which collects the messages requested by users, and makes the list of requests priority, and broadcasts telematics contents through the data channel on DMB. This system enables users to receive the requested telematics contents which are categorized by regions and services. Therefore, the proposed structures help users to receive the distinctive DMB data services. Moreover, the system can reduce the amount of each service data as the service vendors increase the bandwidth of the content requested frequently within the limited bandwidth by collecting and analyzing the requested contents.
