Abstract

System, method, and non-transitory computer-readable storage medium, including: a sensor installed on a section of a road and configured to collect traffic data related to movements of vehicles on the section of the road, wherein the sensor samples the traffic data at a certain interval long enough to substantially reduce the amount of the collected traffic data; a plurality of narrowband network towers configured to relay the collected traffic data received from a plurality of sensors installed on a designated area encompassing multiple sections; and a central server configured to receive and process the collected traffic data from the plurality of narrowband network towers to generate traffic information sufficient to provide accurate real-time traffic information of the designated area.

Claims (38)

1. A traffic data collection system comprising:

a plurality of radar sensors installed on a section of a road and configured to collect traffic data related to movements of vehicles on the section of the road,

wherein each radar sensor of the plurality of radar sensors samples the traffic data at a certain interval long enough to substantially reduce the amount of the collected traffic data,

wherein each radar sensor: (a) radiates radio frequency (RF) electromagnetic waves directed at the section of the road; (b) senses signals reflected by the vehicles on, the section of the road; and (c) determines and collects the traffic data including distance, speed, and angle of the vehicles on the section of the road;

a plurality of narrowband Internet-of-Things (IoT) network towers configured to relay the collected traffic data received from the plurality of radar sensors installed on a designated area encompassing multiple sections of the road; and

a central server configured to receive and process the collected traffic data from the plurality of narrowband IoT network towers to generate traffic information sufficient to provide accurate real-time traffic information of the designated area.

2. The system of claim 1 , wherein the designated area is an entire city.

3. The system of claim 1 , wherein the certain interval is between 1 and 10 minutes.

4. The system of claim 1 , wherein each radar sensor comprises

an RF unit configured to transmit and receive electromagnetic waves onto the vehicles on the section of the road;

a signal processing unit configured to process signals reflected from the vehicles; and

a positioning unit configured to determine and indicate position information of the sensor.

5. The system of claim 4 , wherein the positioning unit is a global positioning system (GPS) unit.

6. The system of claim 4 , further comprising

an encryption unit configured to provide data security for the collected traffic data of each radar sensor.

7. The system of claim 4 , further comprising

a plurality of communication units configured to enable the sensor to communicate with the plurality of narrowband network towers.

8. The system of claim 7 , wherein the plurality of communication units comprises

a Wifi unit and an Ethernet unit configured to enable the sensor to communicate with a mobile device during initial alignment of the sensor.

9. The system of claim 4 , wherein the signal processing unit is also configured to calculate, from the signals reflected from the vehicles, an arithmetic mean of the speed of the vehicles.

10. A traffic data collection method comprising:

collecting traffic data related to movements of vehicles on a section of a road using a plurality of radar sensors installed on the section of the road,

wherein each radar sensor of the plurality of radar sensors samples the traffic data at a certain interval long enough to substantially reduce the amount of the collected traffic data,

wherein each radar sensor: (a) radiates radio frequency (RF) electromagnetic waves directed at the section of the road; (b) senses signals reflected by the vehicles on the section of the road; and (c) determines and collects the traffic data including distance, speed, and angle of the vehicles on the section of the road;

relaying the collected traffic data received from the plurality of radar sensors installed on a designated area encompassing multiple sections of the road using a narrowband Internet-of-Things (IoT) network; and

receiving and processing the collected traffic data from the narrowband IoT network to generate traffic information sufficient to provide accurate real-time traffic information of the designated area.

11. The method of claim 10 , wherein the designated area is an entire city.

12. The method of claim 10 , wherein the certain interval is between 1 and 10 minutes.

13. The method of claim 10 , further comprising

providing data security for the collected traffic data of each radar sensor.

14. The method of claim 10 , further comprising

enabling each radar sensor to communicate with a mobile device during initial alignment of each radar sensor.

15. A non-transitory computer-readable storage medium storing a computer program to collect traffic information, the computer program comprising executable instructions that cause a computer to:

collect traffic data related to movements of vehicles on a section of a road using a plurality of radar sensors installed on the section of the road,

wherein each radar sensor of the plurality of radar sensors samples the traffic data at a certain interval long enough to substantially reduce the amount of the collected traffic data,

wherein each radar sensor: (a) radiates radio frequency (RF) electromagnetic waves directed at the section of the road; (b) senses signals reflected by the vehicles on the section of the road; and (c) determines and collects the traffic data including distance, speed, and angle of the vehicles on the section of the road;

relay the collected traffic data received from the plurality of radar sensors installed on a designated area encompassing multiple sections of the road using a narrowband Internet-of-Things (IoT) network; and

receive and process the collected traffic data from the narrowband IoT network to generate traffic information sufficient to provide accurate real-time traffic information of the designated area.
