Abstract
Abstract To obtain a traffic information providing system which can display information of a forward section of an on-road radio transmission/reception device even if there is no oncoming vehicle. The on-vehicle radio transmission/reception device has a moving time calculation device for calculating moving times of traveling sections which are arbitrarily divided, a memory for storing the moving time calculated by the moving time calculation device, and a transmission device for transmitting the moving time; and the on-road radio reception device has a reception device for receiving a moving time from the moving time calculation device, a recognition unit for recognizing a traffic situation from the moving time to form traffic situation data, a data communication device for transmitting/receiving the traffic situation data between the plurality of on-road radio transmission/reception devices, and a display device for displaying the traffic situation data obtained by the data communication device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
A traffic information providing system comprising an on-vehicle radio transmission/reception device mounted on a vehicle and a plurality of on-road radio transmission/reception devices installed on roads, wherein said on-vehicle radio transmission/reception device has: moving time calculation means for calculating moving times of traveling sections which are arbitrarily divided; moving time storage means for storing the moving time calculated by said moving time calculation means; and transmission means for transmitting the moving time, and said on-road radio transmission/reception device has: reception means for receiving said moving time from said on-vehicle radio transmission/reception device; traffic situation recognition means for comparing said moving time with a preset reference time to form traffic situation data; data communication means for transmitting/receiving said traffic situation data between said plurality of on-road radio transmission/reception devices; and display means for displaying said traffic situation data obtained by said data communication means.
Claim 2
Dependent Claim
143 words
A traffic information providing system comprising an on-vehicle radio transmission/reception device mounted on a vehicle and a plurality of on-road radio transmission/reception devices installed on roads, wherein said on-vehicle radio transmission/reception device has: moving time calculation means for calculating moving times of traveling sections which are arbitrarily divided; moving time storage means for storing the moving time calculated by said moving time calculation means; and transmission means for transmitting the moving time, and said on-road radio transmission/reception device has: reception means for receiving said moving time from said on-vehicle radio transmission/reception device; traffic situation recognition means for comparing said moving time with a preset reference time to form traffic situation data; data communication means for transmitting/receiving said traffic situation data between said plurality of on-road radio transmission/reception devices; and display means for displaying said traffic situation data obtained by said data communication means.
Claim 3
Dependent Claim
55 words
A traffic information providing system according to claim 1, characterized in that said moving time calculation means has a traveling distance detection device for outputting a traveling distance and a timer device for outputting time and calculates a moving time of each traveling section by using said traveling distance detection device and said timer device.
Claim 4
Dependent Claim
107 words
A traffic information providing system according to claim 1, characterized in that said on-road radio transmission/reception device has traveling section information storage means for storing traveling section information serving as information of a plurality of traveling sections in advance and traveling section information transmission means for transmitting said traveling section information to said on-vehicle radio transmission/reception device, and said moving time calculation means has a traveling distance detection device for outputting a traveling distance and a timer device for outputting time and calculates a moving time of each traveling section based on said traveling section information by using said traveling distance detection device and said timer device.
Claim 5
Dependent Claim
55 words
A traffic information providing system according to claim 1, characterized in that said on-road radio transmission/reception device has display information transmission means for transmitting display information displayed by said display means to said on-vehicle radio transmission/reception device, and said on-vehicle radio transmission/reception device has vehicle-side display means for providing said display information to a driver.
Claim 6
Dependent Claim
37 words
A traffic information providing system according to claim 1, characterized in that said on-vehicle radio transmission/reception device and said on-road radio transmission/reception device perform transmission/reception by using a narrow-band communication scheme of an advanced road traffic system.
