1. A method for dynamically detecting pedestrian activity, the method comprising:
receiving one or more data objects from a vehicle, wherein each of the one or more data objects describe one or more attributes of a vehicle trip;
determining, using an image processing model, one or more pedestrian parameters based at least in part on the one or more data objects;
determining whether the one or more pedestrian parameters satisfy one or more pedestrian parameter thresholds;
determining vehicle trip information, wherein a pedestrian flow matrix for a predetermined time range is assigned to the vehicle based at least in part on the vehicle trip information, wherein (i) the pedestrian flow matrix comprises one or more pedestrian flow compartments and (ii) each pedestrian flow compartment is divided at the zip code level, link level, and/or point of interest level and each pedestrian flow compartment is associated with one or more pedestrian parameter thresholds; and
in an instance the one or more pedestrian parameters do not satisfy one or more pedestrian parameter thresholds, causing one or more safety alert warnings to be provided to one or more other vehicles.
