1 Optimizing PennDOT s Snow Routes and Planning Process with GIS Sandra Tosca, P.E. PennDOT District 3-0, District Executive Nate Reck GeoDecisions, Director

2 PennDOT Structure and Facts

3 PennDOT Structure and Facts 67 counties in Pennsylvania Counties are assigned to one of the 11 Engineering Districts Winter Service Responsibilities Central office develops overall policies The district office provides oversight and ensures employees are trained and have adequate resources The county maintenance organizations are responsible for executing winter service plans County Maintenance Organization 1A Engineering District 1 Central Office County Maintenance organization 1B Engineering District 2 County Maintenance Organization 2A

4 PennDOT Structure and Facts Winter Service assets and resources 95,996 snow lane miles 426 stockpiles for winter services 2,393 department force dump trucks available for winter operations 120 anti-icing trucks 4,088 permanent transportation equipment operators 809 temporary transportation equipment operators 304 rental dump trucks 677 municipal winter service agreements 705 agility winter service agreements 4 other winter service agreements

5 PennDOT Structure and Facts Fiscal Year Expenditures exceeded $254 million Winter Materials used 1.2 million tons of salt 854,000 tons anti-skid 10.6 million gallons of salt brine

6 Basic Components

7 Basic Components

8 Basic Components

9 Basic Components

10 Products - GIS Maps Winter stockpile areas Routing of trucks and agreements Material mixes used Planned cycle times Snow lane mileage thresholds for trucks Anti-icing routes and applications rates of material Assignments of specialized winter service equipment

11 Products - Reports Identify gaps or overlaps in service Calculate the department force truck fleet Analyze how the department force truck fleet is used Identify the planned material mixes and application rates by route or truck Identify the number of trucks and snow lane miles assigned to stockpiles Identify unassigned department force equipment

12 Technical Environment ASP.NET using Visual Studio 2012 Bootstrap Oracle Spatial 11g Esri ArcGIS for Server 10 Python Business Objects Crystal Reports

13 Technology Focal Points Oracle Spatial for all GIS data generation and DynSeg functionality Map Plotting done through Python Online mapping done using JavaScript API Single Sign-On with LDAP/Active Directory Security Management and User Roles

14 Assessments Winter Service Fleet Consistency in Level of Service Facility Locations

15 Winter Service Fleet Assessments Range of snow lane mileage assignments by trucks

16 Winter Service Fleet Assessments Trucks with minimal snow lane mileage assignments

17 Winter Service Fleet Assessments Drilling down to individual truck route assignments

18 Winter Service Fleet Assessments Drilling down to individual truck route assignments

19 Winter Service Fleet Assessments Using GIS maps to help optimize routing of trucks with low Snow Lane mile assignments. Map identifies truck assignments by snow lane mileage thresholds.

20 Winter Service Fleet Assessments Network service type by mileage

21 Winter Service Fleet Assessments Unassigned equipment for winter services

22 Consistency in Level of Service Assessment Anti-icing route strategy Application rates gallon/slm

23 Consistency in Level of Service Assessment Material mixes used for spreading storms by mileage

24 Consistency in Level of Service Assessment Using GIS maps to assess the consistency of treatment on primary corridors by using planned materials mixes

25 Facility Location Assessment Opportunities to reduce winter stockpiles

26 Benefits Time savings in map development Time savings for planning and data collection Time savings for calculating truck fleet Analysis tools available to optimize resources Time and dollar savings in verification of assigned agreements
