  4. What is Road Management • Purpose: To optimise the overall performance of the network over time • Goal: To improve the development and performance of the road sector and its use of resources, within the context of national objectives, in order to minimise transport costs.

  5. Road Management • Road Management involves: • Setting priorities • Defining activities • Planning • Allocating resources • Organising and motivating personnel • Controlling work • Monitoring and evaluating performance • Feeding back results to seek improvements

  6. THE IMPACTS OF ROAD MANAGEMENT • Level of service (road condition) The effects of road management can be assessed in terms of the various impacts: • Socio economic impacts • Road user costs • Accident levels and costs • Road administration costs

  7. Components of Total Road Transport Costs in the Economy Road User/Vehicle Operating Construction Maintenance Operation - Fuel Consumption - Oil Consumption - Tyres Wear & Tear - Parts Replacement - Vehicle Depreciation - Travel Time - Accidents

  8. Key Statistics from Emerging Countries • Transport sector is 5 to 10 per cent GDP • Paved roads account for 12% of length and 90% non-urban traffic • In some countries, actual expenditure is 25% of need • Every $ not spent on maintenance increases transport costs by 4$ • Surfacing lives vary from less than 5 to 10 years • Transport fuels and machinery account for 40% of import bill

  9. Weaknesses in Road Management • Inadequate and un-secure funding • Greater priority given to new roads • Poorly motivated organisations • Weak or non existent management systems • Inappropriate treatments and lack of quality control • Poor regulations and/or enforcement • Equipment failures and lack of spares

  10. Pavement Performance Pavement performance depends on: • Traffic volumes and loading • Road pavement strength • Maintenance standards

  22. Truck Damage Factors in Pakistan & USA

  23. Network Roughness Condition Good (<3.5 IRI) * 28% Very Poor (IRI>7.0) 47% 8% Fair (3.5<IRI<5.0) 17% 7365 km two-lane equivalent Poor (5.0<IRI<7.0) network

  24. RIDE QUALITY NETWORK Fair (8.0%) Good (28.0%) Poor (17.0%) Very Poor (47.0%) Network Condition Source: World Bank Study 1998

  25. 1998 NETWORK ANALYSIS - REAMINING SERVICE LIFE  53% of Network has Remaining Service Life of Zero Years.  29% of Network has Remaining Service Life < 3 Years.

  26. RIDE QUALITY & ROAD USER COST VEHICLE OPERATING COST (RS/KM) ROAD ROUGHNESS (MM/KM)

  27. Funding Status

  28. Funding Status

  29. Minimum Budgetary Requirement SCENARIO TO MAINTAIN 1998 CONDITION; MIN. 2-3 BILLION RS PER YEAR * 100% 8.5 90% 80% 7.5 70% 6.5 60% Poor Fair 50% Average Roughness (IRI) Network Condition (%) Good 5.5 Avg.. IRI 40% 4.5 30% 20% 3.5 10% 2.5 0% 1998 1999 2000 2001 2002 2003 2004 Year

  30. NETWORK ANALYSIS - ECONOMIC LOSS OF NON MAINTENANCE  Total Economic Loss : Rs. 38 Billion  Economic Loss due to N-5 Rs. 26 Billion

  31. What SOLUTIONS can we suggest ? • Establish a dedicated and secure Road Fund • Prioritise on a rational and equitable basis • Adopt affordable standards • Implement appropriate management and quality systems • Address transport management, regulation and enforcement issues • Seek to improve road user behaviour and vehicle standards
