Nine Areas of ITS |
|
| (1)Advances in Navigation Systems |
 To improve driver convenience, traffic information is distributed to the driver via the navigation system that is compatible with the on-demand function and information supply units so that optimum behavior concerning the route and travel time can be selected, best distributing the traffic flow. The traffic information includes traffic congestion information for each optional route, required time to the destination, traffic restriction information, and current information on parking availability. The information is also distributed to homes and offices to assist drivers in deciding on an efficient travel plan prior to departure.In addition, service information including the destination's regional information is distributed on demand via the in- vehicle equipment, the parking/service areas along expressways, and the "Michi-no-Eki" (the roadside stations) along ordinary roads.

| (2)Electronic Toll Collection |
 Electronic toll collection is enabled without stopping at the tollgate to eliminate traffic congestion, improve driver convenience by cashless payment,and reduce administrative costs.

| (3)Assistance for Safe Driving |
 To prevent traffic accidents, various types of sensors are used on the road and in the vehicles to collect driving conditions data including the ambient road and vehicle situation. The in-vehicle equipment and road information apparatus are used to provide this driving conditions information and the associated danger warning to each driver in real time.An automatic control function is added to the vehicles to support the driver's operation through speed control by automatic break operation or driving assistance by steering wheel control if danger is detected while, at the same time, considering the position and behavior of the control vehicle and surrounding vehicles, and obstacles. In addition, automatic vehicle driving is implemented with ambient driving environment sensing and advanced driver assistance functions. The latter includes speed control through automatic brake and accelerator operation and steering wheel control.

| (4)Optimization of Traffic Management |
 To improve traffic safety, driving amenities, and the road environment, optimum signal control is implemented for the entire road network as well as for areas with exceptional traffic congestion and damaged roadside environments. Mobile navigation is performed for the driver using in-vehicle equipment and information supply units to administer the traffic. To prevent any secondary disasters induced by a traffic accident, a traffic accident is detected quickly, the traffic control pertinent to the accident is performed, and traffic restriction information is distributed to the drivers through the in-vehicle equipment and information supply units.

| (5)Increasing Efficiency in Road Management |
 Determination of the optimum work period, planning of the working arrangement, and provision of directions to the vehicles are performed by accurately identifying road surface conditions and work vehicle positions to maintain a safe, smooth and pleasant driving environment in accordance with the social condition and nature of each region. In case of a disaster, damage to the road facilities and surrounding areas are identified, and proper road administration is executed through efficient arrangement of road recovery vehicles and the establishment of a rapid recovery system. Special vehicles are properly managed by using an electronic application for special vehicle pass application and transaction processing, generating a database of transport permitted routes, identifying the actual transport routes of the permitted vehicles, and automatically identifying the load weight of passing vehicles with the vehiclle weight scale. In addition,the natural state of rain, snow, fog, wind, and water, and information related to transport restrictions are thereby quickly distributed to the drivers through the in- vehicle equipment and information supply units to maintain safe and smooth traffic flow in accordance with the natural conditions in each region.

| (6)Support for Public Transport |
 Support is given to choose flexible transport measures, transfer and departure time zones suitable for the needs of the public transport users to improve convenience for the users. All information, including the operating state, seat occupancy state, required fares and fees, and parking availability of the public transport facilities is distributed to implement optimum usage of transport facilities. The information is transmitted to terminal units at homes, offices, in-vehicle equipment and portable terminal units, and to information supply units installed in the roads, terminals, bus stops, and expressway service areas. In addition, to improve convenience with safe and smooth operation of the public transport facilities and efficiency of the business administration, the operation and administration of the public transport facilities are supported by real-time collection of the operating status of the public transport facilities, performing priority dispatch as necessary, and distributing the collected information to the public transport companies as basic data.

| (7)Increasing Efficiency in Commercial Vehicles Operations |
 To greatly improve transport efficiency, reduce commercial traffic and improve transport safety, operation administration is supported by real- time collection of operation status of trucks and tourist buses and distributed as basic data to the transportoperators. Efficiency improvement of logistics is supported by establishing the advanced, automated, systematized logistics centers, shared delivery, and distributing return tag information. Multiple commercial vehicles with the automated driving functions drive continuously by keeping a proper vehicular gap.

| (8)Support for Pedestrians |
 To form a safe and pleasant road environment that pedestrians and people without vehicles including the elderly and handicapped can securely use, the facilities, route guidance and routing using portable terminal units, magnetic media and voice are utilized to support the pedestrians. The green light timing of the crossing signal is extended with portable terminal units so that pedestrians can safely cross the road. In addition, for vehicle measures, danger protection is executed to prevent accidents involving pedestrians by detecting pedestrians in the paths of vehicles and warning the driver and/or automatically activating the brakes.

| (9)Support for Emergency Vehicle Operations |
 To implement rapid and proper recovery and rescue activities following a disaster or accident, the vehicle involved automatically notifies the organizations concerned with an emergency message to greatly reduce time for recognizing the disaster or accident and identifying the location.In addition, information about the traffic and road damage conditions are collected in real time and transferred to the organizations concerned to perform rapid routing of recovery vehicles to the site.
