  • Empirical evaluation of Brisbane macroscopic fundamental diagram, Takahiro Tsubota, Ashish Bhaskar, Edward Chung, Australasian Transport Research Forum, ATRF 2013 - Proceedings, 2013/01, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84916918437&origin=inward, The Macroscopic Fundamental Diagram (MFD) relates space-mean density and flow, and the existence with dynamic features was confirmed in congested urban network with real data set from loop detectors and taxi probes. Since the MFD represents the area-wide network traffic performances, it gives foundations for perimeter control strategies and an area traffic state estimation enabling area-based network control. However, limited works have been reported on real world example from signalised arterial network. This paper fuses data from multiple sources (Bluetooth, Loops and Signals) and develops a framework for the development of the MFD for Brisbane. Existence of the MFD in Brisbane network is confirmed. Different MFDs (from whole network and several sub regions) are evaluated to discover the spatial partitioning in network performance representation.
  • Traffic density estimation of signalised arterials with mid-link sinks and sources, Takahiro Tsubota, Ashish Bhaskar, Edward Chung, 20th ITS World Congress Tokyo 2013, 2013/01, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84930183862&origin=inward, This research aims to develop a reliable density estimation method for signalised arterials based on cumulative counts from upstream and downstream detectors. Although traffic density is a key variable for analyzing network performance, its estimation is still challenging due to counting errors associated with urban arterials with mid-link sinks and sources. In order to overcome the issue, CUmulative plots and Probe Integration for Travel timE estimation (CUPRITE) is employed for density estimation. CUPRITE reduces or cancels the counting inconsistencies when vehicles' conservation is not satisfied within a section by utilizing probe vehicles' samples. The method is tested in a controlled environment, and the authors demonstrate the effectiveness of CUPRITE for density estimation in a signalised section.
