Results
Ad-hoc performs better for passengers
•  Improved wait and travel times
Optimisation type has little effect at low demands
Increasing fixed headways provides compromise
•  Small increases in VKTs/drive time
•  Decreases in wait time and efficiency
Onwards and upwards
ž  Which
areas are suitable for a DRT
service? (Zahra, PhD)
ž  How can demand be predicted/
estimated? (Shubham, MPhil)
ž  New optimisation processes and DRT
schemes
WIP: co-modality
ž  Exploring
the effect of shared travel
between parcels and passengers
ž  Shared vehicles è more even spread
of occupancy, better performance
N. Ronald, J. Wang, and R. G. Thompson, “Exploring co-modality using
on-demand transport systems”, submitted to City Logistics 2015.
WIP: daily demands/interactions
ž  Exploring
the influence of others/
information on demand for DRT
ž  More passengers = longer wait,
longer travel è deter people
ž  Fewer passengers = quicker travel
PPTS
ž  IBM’s
vision for future transportation

a person who uses or operates
something; a person who exploits
others
ž  Proof of concept for Melbourne?
ž  Finding/adapting/developing
appropriate solution for the problem
