1. A system, comprising:
- a stopping distance module that determines a stopping distance for a first vehicleapproaching a geographic location, wherein;
the stopping distance module comprises a lookup table including a grid of stopping distances based on velocities for a plurality of vehicles including at least one of a make, a model, and a year for each of the plurality of vehicles, andthe stopping distance is determined based on cross-referencing the at least one of the make, the model, and the year of the first vehicle and a current velocity of the first vehicle on the grid;
a determination module that, in response to determining the stopping distance, determines whether the first vehicle will stop prior to reaching the geographic location; and
a signal module that, in response to determining that the first vehicle will not stop prior to reaching the geographic location, modifies a signal of a traffic light located at the geographic location,wherein at least a portion of said modules comprises one or more of a set of hardware circuits, a set of programmable hardware devices, and executable code stored on a set of non-transitory computer-readable storage media.

Abstract
Smart traffic signal methods are provided. One method includes determining a stopping distance for a vehicle approaching a geographic location and, in response to determining the stopping distance, determining whether the first vehicle will stop prior to reaching the geographic location. The method further includes, in response to determining that the vehicle will not stop prior to reaching the geographic location, modifying a signal of a traffic light located at the geographic location. Systems and computer program products for performing the above method are also provided.

11. A method, comprising:
-
determining, by a processor, a stopping distance for a first vehicle approaching a geographic location, the stopping distance determined by; utilizing a lookup table including a grid of stopping distances based on velocities for a plurality of vehicles including at least one of a make, a model, and a year for each of the plurality of vehicles, and cross-referencing the at least one of the make, the model, and the year of the first vehicle and a current velocity of the first vehicle on the grid; in response to determining the stopping distance, determining whether the first vehicle will stop prior to reaching the geographic location; and in response to determining that the first vehicle will not stop prior to reaching the geographic location, modifying a signal of a traffic light located at the geographic location. - View Dependent Claims (12, 13, 14, 15)

16. A computer program product comprising a computer-readable storage medium including program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
-
determine a stopping distance for a first vehicle approaching a geographic location, the stopping distance determined by; utilizing a lookup table including a grid of stopping distances based on velocities for a plurality of vehicles including at least one of a make, a model, and a year for each of the plurality of vehicles, and cross-referencing the at least one of the make, the model, and the year of the first vehicle and a current velocity of the first vehicle on the grid; in response to determining the stopping distance, determine whether the first vehicle will stop prior to reaching the geographic location; and in response to determining that the first vehicle will not stop prior to reaching the geographic location, modify a signal of a traffic light located at the geographic location. - View Dependent Claims (17, 18, 19, 20)
