1. An traffic management system for programmatically determining traffic management instructions to avoid a second conflict in a roadway after resolving a first conflict on the roadway, the traffic management system comprising:
a memory; and
one or more processors that are configured to execute machine readable instructions stored in the memory to:
detect a first conflict on a roadway for a first vehicle;
determine and transmit a first traffic management instruction for the first vehicle for the first conflict on the roadway;
access characteristics of the first vehicle associated with the first traffic management instruction in response to implementing the first traffic management instruction for the first conflict;
after the first conflict is resolved and the first vehicle is outside an impact region of the first conflict, predict that a second conflict will occur after the first conflict that is caused by the implementation of the first traffic management instruction;
using the characteristics of the first vehicle in responding to the first conflict, determine a healing strategy that is directed to preventing the second conflict from occurring;
determine and transmit a second traffic management instruction in association with the healing strategy for the first vehicle, wherein the second traffic management instruction is transmitted in association with traffic management instructions to other vehicles to implement the healing strategy by a group of vehicles; and
provide instructions to the group of vehicles that have passed the impact region of the first conflict to prevent the second conflict.
