  1. Use of HDM-4 & Its Analytical Frame Work

  2. Target Group Students of Final Year Civil Engineering

  3. Aim • To give an overview of Road management system • To create awareness among students of the use of HDM-IV in assisting road development and management

  4. Why Do we need Roads? The roads are economic arteries of any country

  5. What is Road Management ? It is a set of activities which leads To optimise the overall performance of the network over time

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

  7. Preparations Road ManagementCycle Planning Operations Programming

  8. ROLE OF HDM-4 IN HIGHWAY MANAGEMENT • Planning • Programming • Preparations • Operations

  9. Data Managers Analysis Tools Project Program Strategy Road Road HDM Vehicle Network Works Config . Fleet Models RDWE SEE RUE External Systems Databases, PMS, etc. HDM-4 SYSTEM ARCHITECTURE Model libraries File Converter Core Data can be used in Vehicle Fleets other systems Road Networks Road Works transfer data Projects to external Programmes systems Strategies RDWE : Road Deterioration and Works Effects RUE : Road User Effects , SEE : Safety , Energy and Environmental Effects PMS : Pavement Management System

  10. Integrating HDM-4 within Road Management Systems Long Term Strategic Road Plan Road Inventory DATABASE HDM-4 Road Condition Multi -Year Work Program HDM4 Traffic Data Detailed Project Level Appraisal Bridges Inventory Policies Standards Research Bridges Condition INPUTS OUTPUTS

  11. NETWORK ELEMENTS • Links • Sections • a length of road that is homogeneous in terms of its physical attributes (basic unit of analysis) • Network • Sub-networks

  12. PAVEMENT CONDITION • Roughness surveys • Road Distress Surveys • Deflections

  13. TRAFFIC DATA • Volume AADT (MT and NMT) • Traffic Composition and growth rates • Categories - Normal, Diverted, Generated • Axle loading • Traffic flow pattern • Roadside friction

  14. Calibration To Local Conditions • Vehicle Fleet • Unit Costs • Works Standards • Model Calibration • Language

  15. Works Standards • Works types • maintenance • improvement • Unit costs • Construction quality • material properties • construction quality • compaction, etc.
