Abstract

Embodiments relate to traffic control resource planning. An aspect includes receiving information about available routes in a transportation network and receiving an estimate of a traffic demand in the transportation network. Traffic control planning is performed and it may include: simulating a traffic flow based on the available routes and the traffic demand; applying a model that varies traffic control agent (TCA) placement and traffic signal settings in the transportation network to minimize a cost associated with the traffic flow, the cost including a TCA deployment cost and a traffic delay cost; and outputting a traffic control plan based on the applying, the traffic control plan including a TCA placement and traffic signal setting plan.

Claims

1. A system for traffic control resource planning, the system comprising:

a memory having computer readable computer instructions; and

a processor for executing the computer readable instructions to perform a method comprising;

receiving information about available routes in a transportation network;

receiving an estimate of a traffic demand in the transportation network; and

performing traffic control planning, the performing including;

simulating a traffic flow based on the available routes and the traffic demand;

applying a model that varies traffic control agent (TCA) placement and traffic signal settings in the transportation network to minimize a cost associated with the traffic flow, the cost including a TCA deployment cost and a traffic delay cost; and

outputting a traffic control plan based on the applying, the traffic control plan including a TCA placement and traffic signal setting plan.

2. The system of claim 1, wherein the traffic demand is determined based on a planned event.

3. The system of claim 1, wherein the traffic demand is determined based on an unplanned event.

4. The system of claim 1, wherein the traffic flow includes vehicular traffic and pedestrian traffic.

5. The system of claim 1, wherein the transportation network includes vehicular roadways and pedestrian roadways.

6. The system of claim 1, wherein a number of TCAs available for TCA placement is fixed.

7. The system of claim 1, wherein the TCA placement takes into account TCA shift constraints.

8. The system of claim 1, wherein the model is further applied to quantitatively predict a difference in the cost between the traffic control plan and a second traffic control plan.

9. The system of claim 1, further comprising implementing the traffic control plan.

10. The system of claim 9, further comprising updating the model based on an actual traffic flow observed after the implementing.
