Abstract

A technique for showing running time by sections for a tollway includes: a unit toll collector installed at a unit toll gate of a tollway for calculating a running time of vehicles leaving the unit toll gate for each entrance toll gate; indicators installed at main points of the tollway for indicating running time by sections; and a traffic control center connected to the unit toll collector and a predetermined communication network for receiving the running time of vehicles for each entrance toll gate, averaging it to obtain the overall running time by sections, and outputting it to the indicators.

Claims

1. A method of showing running time by sections on a tollway, comprising the steps of:

receiving an average running time of vehicles leaving a unit toll gate from a unit toll collector installed at the unit toll gate at predetermined time intervals;

classifying the average running time provided from the unit toll collector for each entrance toll gate;

calculating an average distribution from the average running time;

calculating an overall average running time by averaging running time while data deviating from a predetermined value are excluded from the average distribution obtained; and

indicating the overall average running time on an indicator.

2. The method as claimed in claim 1, further comprised of the calculating the overall average running time in the unit toll collector comprising the steps of:

collecting information of a vehicle passing an exit toll gate as to its incoming toll gate, the incoming toll gate passing time, and the exit toll gate passing time for a predetermined time;

classifying the collected information for each entrance toll gate;

obtaining an average distribution in accordance with running time from data from the classified collected information; and

obtaining an average running time for each entrance toll gate on the basis of data remaining after excluding data deviating from the predetermined value from the average distribution obtained.

3. The method as claimed in claim 2, further comprising the step of compensating for time relate to toll collection in the average running time obtained for each entrance toll gate.

4. A system for showing running time by sections on a tollway, comprising:

a means for receiving an average running time of vehicles leaving a unit toll gate from a unit toll collector installed at the unit toll gate at predetermined time intervals;

a means for classifying the average running time provided from the unit toll collector for each entrance toll gate;

a means for calculating an average distribution from the average running time;

a means for calculating an overall average running time by averaging running time while data deviating from a predetermined value are excluded from the average distribution obtained; and

a means for indicating the overall average running time on an indicator.

5. The system as claimed in claim 4, further comprised of the means for calculating the overall average running time in the unit toll collector comprising:

a means for collecting information of a vehicle passing an exit toll gate as to its incoming toll gate, the incoming toll gate passing time, and the exit toll gate passing time for a predetermined time;

a means for classifying the collected information for each entrance toll gate;

a means for obtaining an average distribution in accordance with running time from data from the classified collected information; and

a means for obtaining an average running time for each entrance toll gate on the basis of data remaining after excluding data deviating from the predetermined value from the average distribution obtained.

6. The system as claimed in claim 5, further comprising a means for compensating for time related to toll collection in the average running time obtained for each entrance toll gate.

7. A method of collecting running time by sections on a tollway, comprising the steps of:

determining if a predetermined data collection time has been reached;

upon the predetermined data collection time having been reached, collecting data of vehicles passing per unit time by lanes and kinds;

classifying the collected data for each entrance toll gate;

obtaining an average distribution in accordance with running time;

excluding data deviating by a predetermined value from the average distribution;

obtaining an average running time for each entrance toll gate;

compensating for time delay taken during toll collection; and

storing an average running time by entrance toll gate and number of passing vehicles by kinds.

8. A method of showing running time by sections on a tollway, comprising the steps of:

determining if a predetermined data collection time has been reached;

upon the predetermined data collection time having been reached, collecting data of vehicles passing per unit time by lanes and kinds;

classifying the collected data for each entrance toll gate;

obtaining an average distribution in accordance with running time;

excluding data deviating by a predetermined value from the average distribution;

obtaining an average running time for each entrance toll gate;

storing the average running time by entrance toll gate and number of passing vehicles by kinds; and

indicating the average running time by sections on an indicator.
