2015 iMoD workshop, 20 Feb 2015

On Friday 20 February 2015, the third annual iMoD workshop took place at the University of Melbourne.

Discussions at the 2015 iMoD workshop.

This year, we have several research students working on the iMoD project, so we had a range of in-depth 20 minute presentations to 5 minute lightning presentations from those who have recently joined the project.

Our subprojects range from comparing simulation tools, simulation of DRT services and feeder buses, understanding mobility from GPS traces, simulating shared passenger/freight services, and providing information for decision making about rideshare options. We also provided updates on our engagement activities (including events such as #infrahack and Melbourne Knowledge Week) and travels (to conferences such as TRB, ITSC, and GIScience). The updates and feedback from industry partners was also very useful.

Over the next year, we will focus on bringing together all these strands, focusing on demand generation for DRT and developing decision support tools to assist decision makers in implementing DRT services in Victoria and elsewhere.

CAITR 2015: hosting and more DRT

Shubham Jain will be attending CAITR (Conference of Australian Institutes of Transport Research) on 12-13 February, hosted by the Melbourne School of Engineering. He will be presenting work-in-progress on his MPhil thesis, focusing on the simulation of demand for demand-responsive transportation.

Mobility and accessibility is a problem for growing cities. To meet this challenge in a sustainable way, taking congestion, fuel consumption, and environmental impacts into consideration, new forms of transport need to be considered. One possible solution is Demand Responsive Transport System (DRTS) which provides flexible point-to-point service on casual requests. It operates at flexible routes and does not have pre-defined schedules. Before deploying a DRTS, we need to simulate the facility and we require to predict travel demand for it. Activity-based micro-simulation models for travel demand explicitly recognise that individuals and households are the actual decision makers, and that travel demand is derived from travellers’ desire to participate in spatially dispersed activities. This research attempts to predict travel demand for DRTS using activity based modeling. This paper presents early research and findings on generating synthetic population of city of Melbourne using PopGen and PopSynWin software and their comparison. Further research would assign travel diaries to synthetic population using Victorian Integrated Survey of Travel and Activity (VISTA) data and predict mode shift to DRTS.

Joann Yang, a research assistant in Infrastructure Engineering at the University of Melbourne, will also present a literature review on on-demand freight transportation. This is part of another paper in preparation for the upcoming City Logistics conference, which uses the demand-responsive transport simulations developed as part of the iMoD project to explore on-demand, shared passenger/goods travel.

Note that both Russell Thompson and Nicole Ronald are involved in organising CAITR, so will be present as well. We are looking forward to welcoming all the participating students, researchers, and practitioners from around Australia!
