  • Abstract:
    This study developed a new snow model and a database which warehouses geometric, weather and traffic ; data on New Jersey highways. The complexity of the model development lies in considering variable road ; width, different spreading/plowing patterns for mainlines and ramps, actual (traffic dependent) and ; recommended plowing/spreading speeds and the use of mixed truck types. On the other hand, the complexity ; of the developing database lies in extracting geometric details of study road sections, estimating/mapping ; traffic speed considering the severity of weather (i.e. snow intensity), time of a day (i.e., peak/off-peak period ; and weekday/weekend), and roadway type (i.e., urban/rural freeways/arterials). The developed model was ; applied to three maintenance yards in New Jersey which demonstrates its dynamic and flexibility in adapting to ; various circumstances (i.e., geometry, weather, and traffic) in estimating needed fleet size for salt spreading ; and snow plowing operations for various scales (i.e., section, crew, yard, region, and statewide). The model ; outcomes can be used to assist managers to determine the required number of contractor trucks before a ; winter season and during/after a snow storm based on forecasted weather and traffic condition. The objective ; of this study is to assist the New Jersey Department of Transportation (NJDOT) in developing a method to ; estimate quantity of salt and fleet size for winter highway maintenance in the State of New Jersey.
