Identification of rolling multiyear work programs for road network: HDM-4 strategy analysis with dynamic sectioning

Propose an approach to identification of work program for road network using HDM-4 strategy analysis with dynamic sectioning. | ISSOT- 2006 Bangkok Thailand IDENTIFICATION OF ROLLING MULTIYEAR WORK PROGRAMS FOR ROAD NETWORK HDM-4 STRATEGY ANALYSIS WITH DYNAMIC SECTIONING Saitama Univ. ter by ora- i University of c ersi W i It ISSOT 2006 Enhancing the Quality of Life through Transportation ______13 -16 Nov. 2006_____ Better life through transportation Poor road maintenance - poor level of services No comfort traffic accident Speed reduce congestion Environmental issues dust noise . etc. 2 Better lever of service Better lever of service need a large amount of money However Constrained budget -ỳ how to maintain road networks in effective economic ways 3 What is HDM-4 The Highway Development and Management System HDM-4 developed by the World Bank is a decision-support tool for investigating road investment alternatives such as to find optimal road maintenance program strategies HDM-4 is used widely Using the calibration factors - use in diverse conditions Involving agency costs user costs in pavements and conditions of use Being used as an appropriate design tool for pavements Tsuno awa Ul-Islam 2003 6 1 HDM-4 Applications Programme Analysis in HDM-4 Management Function HDM-4 Application Planning Strategy Analysis Programming Programme Analysis Preparation Project Analysis Operations -- Research all Programme Analysis deals with the priority analysis of a defined long list sub-network to find a list of road section for single or multiyear work program under budget constrain Containing subjectively defined road sections The Objectives Propose an approach to identification of work program for road network using HDM-4 strategy analysis with dynamic sectioning. Definition Dynamic Sectioning Approach With Dynamic Sectioning Approach homogenous road sections are defined when a predefined jump is detected in one or more parameters such as pavement condition traffic volume etc. as you drive along the network 9 10 Challenge Dynamic Sectioning Approach in SA Maximum number of maintenance alternatives for
