Influencing Factors • Traffic Growth • Capacity • Safety • Heavy Vehicle Percentage • Future Mobility Needs as Identified in MDP/Planning Division • Economic Development/Recreational Needs • Connectivity to Provincial Highway System • Future Roadway Classification • Significance factor • Any other factors Rural Road Study 14

Influencing Factors • Traffic Growth 1.5 • Capacity 1.6 • Safety 1.0 for now but increase when sufficient data available • Heavy Vehicle Percentage 1.6 • Future Mobility Needs as Identified in MDP/Planning Division 1.4 • Economic Development/Recreational Needs 1.6 • Connectivity to Provincial Highway System 1.4 • Future Roadway Classification 1.4 • Significance factor 0.5 • Any other factors as required Rural Road Study 15

Database • In Access(Microsoft) Format – for ROHI purposes • Based on weighting criteria and influencing factors the correct roads seem to be coming to the top. • Once migration to county database is complete more stability and functionality can be added Rural Road Study 19

Next Steps • Migrate to County GIS Data Base • Integrate intersection data • Develop data entry/revision functions to facilitate database up-keep • County’s Road Assets to be summarized Rural Road Study 20
