  7. Road Rehabilitation Budget Allocation

  8. 2009 Visual Condition Assessment Outcomes Constraints • All roads Visual Condition Index (VCI) > 30 • All category A & B roads VCI > 50 • < 10% category C & D roads VCI < 50 • Average VCI of entire network > 70 Outcomes

  9. Consequential Road Life-spans

  10. Challenges …. 1 • Condition Assessment • Based on Visual Condition Index (TRH 22) • Subjective • Quality and significance of data • Excessive data captured for minor roads (75% of network) • Slow assessment rate • Mechanical testing preferable • Generates large quantities of data

  11. Challenges …. 2 • Network Level versus Project Level Analysis • 60% conversion rate (by project) • Optimisation on greatest benefit/cost - not area • Analysis based on links (intersection to intersection) • Network Variability • Ad hoc development (intersection improvements, widenings, etc.) • No “As Built” records

  12. Challenges …. 3 • GIS Issues • Corporate GIS Co-ordination • Subservient to Property Management System • Asset identifier (Road ID) not “owned” by Roads Provision Department • Accounting Issues • Legislated register (MFMA) on accounting system (JD Edwards) • Separate database from GIS & PMS

  13. Challenges …. 4 • Skills Shortages • Highly specialised field • Few practitioners country wide • Roads Provision staff :- • 1 Technologist • 1 Technician (no experience) • 1 GIS officer
