statistical analysis
Mixed Research Method
(Qualitative only / Quantitative only )
binifit of mixed method
using questionnaire and interview
techniques to obtain quantitative and qualitative data respectively.
bridge the rift between quantitative and
qualitative research
develop techniques that are closer to what they actually use in practice
Surveys based on the two elements of a questionnaire and interviews, to obtain
both qualitative and quantitative data
GIS-based modelling to develop decision support aid
Case study to test the model
Approach(Abductive)
to identify factors affecting
pavement maintenance prioritisation (Deductive)
these factors are to be rated in terms of
their importance by professionals from different local authorities
interviews are to be conducted with experts in the field to justify the rated factors. (Inductive)
Stategy(Mixed Methods
Research (Survey, Case
study) )
Time Horizon (cross-sectional)
working on multi-tasks
reviewing
literature
collecting data
developing the model over the same period.
Techniques and Procedures
Questionnaire survey to establish the
most significant factors
affecting
pavement maintenance management decisions;
Interviews with
experts
from different local authorities to justify the rated
factors
case study data within the
Surrey County Council
to test the model
