Systems, methods, and program products for adjusting travel patterns on roadways using sensor nodes

A computer program product stored on a non-transitory computer-readable storage medium, that, when executed by a computing system, adjusts travel patterns for an autonomous vehicle on a roadway, the computer program product comprising program code for:

• detecting a first sensor node of a plurality of sensor nodes, the plurality of sensor nodes positioned on the roadway;
• obtaining positional data for the first sensor node and each subsequent sensor node of the plurality of sensor nodes positioned at least one of adjacent to or downstream from the first sensor node;
• generating a modified travel pattern for the autonomous vehicle based on at least one of:
• the positional data for each sensor node of the plurality of sensor nodes on the roadway, or
• an accessibility status for each sensor node of the plurality of sensor nodes on the roadway, the accessibility status including:
• an open status, or
• a restricted status;
• adjusting an initial travel pattern of the autonomous vehicle on the roadway to the modified travel pattern;
• and
• controlling the autonomous vehicle to travel along the modified travel pattern,
• wherein generating the modified travel pattern for the autonomous vehicle further includes:
• determining the positional data for each sensor node of the plurality of sensor nodes on the roadway;
• comparing the determined positional data for each sensor node of the plurality of sensor nodes with historical position data for each sensor node of the plurality of sensor nodes, the historical position data specific to each sensor node of the plurality of sensor nodes;
• and
• in response to the determined positional data for each sensor node of the plurality of sensor nodes not deviating from the historical position data for each sensor node of the plurality of sensor nodes beyond a sensor node threshold, maintaining the modified travel pattern for the autonomous vehicle based on the positional data and the historical position data.
