Abstract
It is possible to control a car group having a probe car at the head thereof or a whole traffic flow including the car group, with due regard to the efficiency, safety and environment. A probe car system includes a device for inputting a control strategy and/or a car group strategy, based on a road map database or traffic data; a device for evaluating propriety of the strategy and determining a proper strategy; and a device for transmitting the proper strategy to the probe car.
Claims16
A probe car control method for controlling behavior of cars, comprising the steps of:
- inputting a control strategy concerning behavior of a probe car and/or a car group strategy concerning behavior of a car group having a probe car at head thereof, based on a road map database or traffic data collected in real time;
- evaluating propriety of the strategy;
- and
- transmitting a proper strategy to the probe car to control the probe car.
A probe car control apparatus for controlling behavior of cars, comprising:
- a road map database;
- a car group control strategy input section for inputting a control strategy concerning behavior of a probe car and/or a car group strategy concerning behavior of a car group having a probe car at head thereof, based on a road map database or traffic data collected in real time;
- a car group control strategy evaluating and determining section for evaluating propriety of the strategy and determining a proper strategy;
- and
- a car group control strategy transmission section for transmitting the proper strategy to the probe car.
A probe car control apparatus for controlling an intersection signal, comprising
- a map database;
- a car group strategy input section for inputting signal indication schedule data so as not to divide a car group having a probe car at head thereof by a red light, based on the database or traffic data collected in real time;
- and
- a car group control strategy evaluating and determining section for evaluating propriety of the signal indication schedule data and determining proper signal indication schedule data.
