Patent attributes
Aspects provide a roadway management device having a processor configured to collect roadway attribute data associated with accidents within accident data and assign positive correlation values to roadway attributes that match the accident data. Aspects cluster subsets of the accidents that share common values of subset of the roadway attributes assigned positive correlation values; select a corrective action to obviate a one of the clustered roadway attributes; determine whether implementation of the selected corrective action has reduced occurrences of accidents matching common accident data of the clustered accidents on a relevant roadway; and increase a selection weighting value of the selected corrective action in response to determining that implementation has reduced accident occurrences. The selection weighting value is used to bias selection for implementation to obviate a roadway attributes with respect to other clustered accidents.
