According to the travel time measuring device of the present invention, the traffic information relating to the operation of the vehicle on the road traffic network is collected and the information data is processed.
It is possible to provide one type of information (a quiet pattern, a normal pattern, a crowded pattern), and it is possible to realize a traffic control system that provides more detailed and accurate information than before. Therefore, even if a large number of vehicles move at once, it becomes possible to select a driving schedule quickly by presenting accurate and detailed traffic conditions to the driver of each vehicle, and driving vehicles on the road network. It is possible to improve efficiency of time and interval dispersion. In addition, the traffic control system side can also decentralize the system load and make optimal use of the road traffic network. Furthermore, in the case of traffic congestion that tends to be concentrated locally for a period of time, it is possible to avoid or alleviate the traffic congestion, which reduces the driving burden on the driver side, and vehicle accidents that tend to occur during traffic congestion occur. The number of cases can be reduced. At the same time, it is effective as environmental pollution and energy saving measures.

And a traffic control status collection device, wherein the speed collection device collects speed data from traffic data (traffic volume, occupancy rate) and average vehicle length, It is provided in a state of being connected to the determination unit, the traffic congestion status collecting device is for determining the congestion degree of the traffic situation from the traffic volume-occupancy ratio correlation curve, and is provided in a state of being connected to the determination unit. The signal control status collecting device is for observing a traffic signal control and control state controlled according to a road traffic environment and collecting data, and is provided in a state of being connected to the determination unit, wherein the determination Is a device that receives traffic data sent from a speed collection device, a traffic jam condition collection device, and a signal control situation collection device, patterns the traffic jam condition, and calculates the travel time to the destination. The information providing device is provided with the pattern information from the determination unit,
The travel time is organized to give traffic information to the driver who is driving the vehicle, and the travel time to the destination is measured by a semi-free pattern type. It is possible to provide three types of information (disturbance pattern, normal pattern, congestion pattern) to the driving driver using an information board, etc., depending on traffic conditions, and more detailed and accurate information than before. A travel time measuring device characterized by being provided.
