1. A vehicle system comprising:
- at least one environmental sensor programmed to collect traffic information representing movement of a plurality of surrounding vehicles relative to a host vehicle; and
a processing device programmed to receive the traffic information, generate a traffic complexity index based at least in part on the traffic information, compare the traffic complexity index to a predetermined threshold, and generate a traffic alert signal if the traffic complexity index exceeds the predetermined threshold,wherein the processing device is programmed to generate the traffic complexity index based at least in part on a longitudinal complexity value and a lateral complexity value,wherein the longitudinal and lateral complexity values are associated with the longitudinal and lateral movement, respectively, of the plurality of surrounding vehicles,wherein the processing device is programmed to generate the traffic complexity index by aggregating the longitudinal complexity value and the lateral complexity value from each of the plurality of surrounding vehicles.
