Abstract

Various systems and methods for a roadside network. The roadside network includes one or more processors to receive gather traffic data from a first set and a second set of sensors associated with a first sector and second sector, respectfully. A minimum forward visibility range is determined. Portions of the sectors overlap to provide the minimum forward visibility range. Processed traffic data is generated based on the traffic data for both sectors. The processed traffic data is then sent to antennas to be transmitted to the respective sector.

First claim

1. A system for a roadside network, the system comprising:
one or more electronic processors configured to:
receive, from a first plurality of sensors, first traffic data associated with a first sector;
determine a minimum forward visibility range;
generate first processed traffic data based on the first traffic data;
send, to a first plurality of antennas, the first processed traffic data to transmit first processed traffic data within the first sector;
receive, from a second plurality of sensors, second traffic data associated with a second sector, wherein a first portion of the first sector overlaps a second portion of the second sector to provide the minimum forward visibility range;
generate second processed traffic data based on the second traffic data;
send, to a second plurality of antennas, the second processed traffic data to transmit the second processed traffic data within the second sector;
identify a traffic scenario on the first sector and the second sector;
determine key performance indicators based on the identified traffic scenario for the roadside network;
determine a configuration of the roadside network that meets the key performance indicators; and
reconfigure the first plurality of sensors, the second plurality of sensors, the first plurality of antennas, and the second plurality of antennas to meet the key performance indicators.

2. The system of claim 1 , wherein the one or more electronic processors are further configured to determine a minimum backward visibility range.

3. The system of claim 2 , wherein the first portion of the first sector overlaps a second portion of the second sector to provide the minimum backward visibility range.

4. The system of claim 1 , wherein the one or more electronic processors are further configured to:
connect, using a first plurality of switches, the first plurality of sensors to the first central processing unit and to connect the first central processing unit with the first plurality of antennas; and
connect, using a second plurality of switches, the second plurality of sensors to the second central processing unit and to connect the second central processing unit with the second plurality of antennas.

5. The system of claim 1 , wherein a communication range of the first sector is defined by a range of the first plurality of antennas.

6. The system of claim 1 wherein a sensor range of the first sector is defined by a range of the first plurality of sensors.

7. The system of claim 1 , wherein the reconfiguration changes a communication range of the first sector based on a number of antennas within the first plurality of antennas.

8. The system of claim 1 , wherein the reconfiguration changes a sensor range of the first sector based on a number of sensors within the first plurality of sensors.

9. The system of claim 1 , wherein the traffic scenario is identified based on a traffic flow of vehicles on the first sector and the second sector.

10. The system of claim 1 , wherein the traffic scenario is identified based on a traffic density of vehicles on the first sector and the second sector.

11. A machine-implemented method for a roadside network, the method comprising:
receiving, from a first plurality of sensors, first traffic data associated with a first sector;
