Managing Roadway Intersections For Vehicles
The disclosure includes embodiments for managing roadway intersections for vehicles. A method includes receiving, at a connected roadway device, request messages from a first vehicle and an other vehicle to reserve an intersection. The method further includes checking time-token balances associated with the first vehicle and the other vehicle. The method further includes responsive to the time-token balances being positive for both of the time-token balances, reserving the intersection for the first vehicle based on the request messages. The method further includes transmitting reservation data to the first vehicle and the other vehicle. The method further includes transmitting a traffic light control message to a traffic light, wherein the traffic light control message instructs the traffic light to display a green light while the first vehicle moves through the intersection.

- 1. A computer-implemented method comprising:
receiving, at a connected roadway device, request messages from a first vehicle and an other vehicle to reserve an intersection; checking time-token balances associated with the first vehicle and the other vehicle; responsive to the time-token balances being positive for both of the time-token balances
the first vehicle being associated with a high urgency level, and the other vehicle being associated with a low urgency level, reserving the intersection for the first vehicle based on the request messages;
transmitting reservation data to the first vehicle and the other vehicle; transmitting a traffic light control message to a traffic light, wherein the traffic light control message instructs the traffic light to display a green light while the first vehicle moves through the intersection; and adding to a corresponding time-token balance associated with the other vehicle based on the other vehicle being associated with the low urgency level and the other vehicle not receiving priority for the intersection.
- 8. A system comprising:
one or more processors of a connected roadway device that includes a non-transitory memory storing computer code which, when executed by the one or more processors causes the one or more processors to:
receive request messages from a first vehicle and an other vehicle to reserve an intersection;
check time-token balances associated with the first vehicle and the other vehicle;
responsive to the time-token balances being positive for both of the time-token balances, the first vehicle being associated with a high urgency level, and the other vehicle being associated with a low urgency level, reserve the intersection for the first vehicle based on the request messages;
transmit reservation data to the first vehicle and the other vehicle;
transmit a traffic light control message to a traffic light, wherein the traffic light control message instructs the traffic light to display a green light while the first vehicle moves through the intersection; and
add to a corresponding time-token balance associated with the other vehicle based on the other vehicle being associated with the low urgency level and the other vehicle not receiving priority for the intersection.
- 15. A non-transitory memory encoded with a computer program, the computer program comprising instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
receiving, at a connected roadway device, request messages from a first vehicle and an other vehicle to reserve an intersection; checking time-token balances associated with the first vehicle and the other vehicle; responsive to the time-token balances being positive for both of the time-token balances
the first vehicle being associated with a high urgency level, and the other vehicle being associated with a low urgency level, reserving the intersection for the first vehicle based on the request messages;
transmitting reservation data to the first vehicle and the other vehicle; transmitting a traffic light control message to a traffic light, wherein the traffic light control message instructs the traffic light to display a green light while the first vehicle moves through the intersection; and adding to a corresponding time-token balance associated with the other vehicle based on the other vehicle being associated with the low urgency level and the other vehicle not receiving priority for the intersection.
