Background Aim Objectives
Background
early systems
1990s
performance prediction,
network-level
project-level optimisation
GIS= spatial analysis+ visualization
many factors prioritise maintenance and funding
identifying the factors
MCDM trade-off
model + validation interviews
Rationale of Research
assessment scheme is based
on numerical condition indices
present all factors in a rational manner - reflect the importance placed on them by road authorities = no sound physical meaning
Research Questions
What are the most significant factors
How significant is using GIS
Aim
develop a GIS-based decision support model
Objectives
investigate the current PMMP,principles, challenges.
establish significant factors
explore the best practices on PMMP with GIS
specify a conceptual model MCDA+GIS
implement
validate
