Early smart city applications enabled more complex future projects. One example of this is the Public Transport Information and Priority System (PTIPS) which provides traffic signal priority for delayed buses in the New South Wales transit network. It relies on earlier Smart Cities oriented technology including actuated signals (SCATS), on-board global positioning systems (GPS) and occupancy data from transit smart cards to extend green time for buses that are running late. This presentation examines the leveraged benefit of the earlier projects by estimating the reduction in delay and uncertainty gained by PTIPS.
To validate the benefits of PTIPS, we combine General Transit Feed Specification (GTFS) realtime data with information about the schedule (GTFS static) and the locations of SCATS signals. We test the hypothesis that the reduction in delay is correlated with the number of signalised intersections between bus stops when controlling for the total number of intersections, the distance between stops, and the type of land use.
In addition to measuring the benefit of PTIPS as a Smart City application, this research also serves to motivate legacy investments that might enable the next generation of Smart Cities Projects. This validation has bearing on future Smart Cities project appraisals in terms of direct advantages and quantifying the wider economic benefits.

Dr Emily Moylan | University of Sydney
Dr Emily Moylan is a Lecturer of Transport at the School of Civil Engineering, University of Sydney, where she researches the stochasticity of transport system performance. Emily has worked with Transport for New South Wales on travel time prediction and the development of journey-time reliability models. Her research is translated into practice via technical reports for Transport for New South Wales and the US Transit Cooperative Research Program. After completing her PhD at ANU, she studied Transport at University of California, Berkeley. From 2014-2018, she was a research associate at the Research Centre for Integrated Transport Innovation at UNSW Sydney
