Policy cost implications

Policy Cost Implications

  • High Volume Arterials ($0.89 – $1.3 Billion)

    • $350 - $518 Million More than Conventional HMA

    • $89 - $98 Million Less than Minimum Concrete

  • TOIP Priority Corridors ($985 Million)

    • $390 Million More than Conventional HMA

    • $99 Million Less than Minimum Concrete

  • FDM Delay Restricted Routes ($1.4 Billion)

    • $548 Million More than Conventional HMA

    • $139 Million Less than Minimum Concrete

  • Freight Routes = Backbone System ($1.3 Billion)

    • $518 Million More than Conventional HMA

    • $131 Million Less than Minimum Concrete


Final policy recommendation

Final Policy Recommendation

  • Factor of All (High Volume Arterials, TOIP, Freight, and FDM Delay Corridors)

    • Driving Need: Traffic Demand

      • 1000 VPH (2013 data)


Recommended applications

Recommended Applications
