Abstract
A traffic flow measuring apparatus includes a processor configured to judge a size of a vehicle, depending on a detection frequency or a non-detection frequency of a reflected wave from the vehicle with respect to a transmission wave transmitted from a radar apparatus, within a detection time of the reflected wave from the vehicle, set according to the detection of the reflected wave.
Claims20
A traffic flow measuring apparatus comprising:
- a storage unit configured to store a program;
- and
- a processor configured to execute the program and perform a process including
- judging a size of a vehicle depending on a number of times a reflected wave from the vehicle is detected within a detection time with respect to a transmission wave transmitted from a radar apparatus to the vehicle, wherein the detection time is set according to the detected reflected wave.
A traffic flow measuring method comprising:
- transmitting a transmission wave from a radar apparatus and receiving by the radar apparatus a reflected wave from a vehicle with respect to the transmission wave;
- and
- first judging a size of the vehicle, by a processor of the radar apparatus, depending on a number of times the reflected wave from the vehicle is detected within a detection time, wherein the detection time is set according to the detected reflected wave.
A non-transitory computer-readable storage medium having stored therein a program for causing a computer to execute a process comprising:
- transmitting a transmission wave from a radar apparatus and receiving a reflected wave from a vehicle with respect to the transmission wave;
- and
- judging a size of the vehicle depending on a number of times the reflected wave from the vehicle is detected within a detection time, wherein the detection time is set according to the detected reflected wave.
