Dr Long Truong of ARRB receives SIDRA SOLUTIONS Postgraduate Award 2017

by Australian Road Research Board on February 28, 2018

Dr Long Truong, Senior Professional Leader, Future Transport Technology at ARRB, has won the SIDRA SOLUTIONS Postgraduate Award 2017 for his PhD thesis titled 'Combination Effects of Public Transport Priority Measures'.

On Tuesday 27 February, Rahmi Akcelik of SIDRA SOLUTIONS presented Dr Truong with the award at the ITEANZ annual breakfast meeting.

The SIDRA SOLUTIONS Postgraduate Award was initiated in 2014. This award is presented to the most outstanding postgraduate student from a tertiary institution in Australia or New Zealand, based on the quality of his or her research paper and potential to make a significant contribution to the profession.

In his thesis, Dr Truong has explored the combination effects of providing single or groups of public transport priority initiatives, including bus lanes, queue jump lanes, and transit signal priority. Using traffic microsimulation and kinematic wave theory, he discovered that combining transit signal priority with bus lanes or queue jump lanes can create synergy effects while providing priority at multiple locations, i.e. road sections and intersections, can create multiplier effects. These intriguing findings suggest considerable benefits from providing priority initiatives in combination.

Dr Truong also developed several new methodologies in the field of traffic engineering, such as new offset optimisation models, functions for estimating bus delay reduction associated with priority initiatives, and a coordinated transit signal priority control model. Particularly, he proposed new methods to compute the minimum number of runs required to achieve reliable multivariate performance estimates of a simulated traffic network.

Here are two papers based on this research:

'Analytical and simulation approaches to understand combined effects of transit signal priority and road-space priority measures' 

'Does Combining Transit Signal Priority with Dedicated Bus Lanes or Queue Jump Lanes at Multiple Intersections Create Multiplier Effects?'
