A second stop line for better traffic management in Australia
Previous research has shown the start-up loss problem but more exploration is required into a potential solution. This research aims to demonstrate the hypothesis that using 'Second Stop Line' (SSL) to enlarge stopping distance could shorten the start-up loss time, and as a result, it could help improve the efficiency of queuing vehicles' departure at signalised intersection.
Strategies for rapid congestion recovery using ramp metering
Ramp metering is usually designed to delay the onset of motorway congestion. However, increasing traffic demand and field constraints, such as ramp queue limitation, makes congestion unavoidable. This research examines ramp metering from a different angle, using it to quickly recover a free flow state on the motorway as the demand decreases.
The development of a naturalistic car following model for assessing managed motorway systems
This research targets microscopic behavioural sub-models and it compares existing car following models against precise traffic measures such as headways and time to collision. It is anticipated that the major outcome of this research will be a more realistic car following model that will be effective in evaluation of managed motorway systems and particularly in traffic safety studies. Traffic safety indicators are going to be used for the final proposed model assessment.
The harmonisation of eco-driving and intersection signals for enviromental-friendliness
Eco-driving is an innovative method of driving which has benefits in road safety, environmental impact, driver comfort and fuel savings. However, gentle driving behaviour may negatively affect non-eco drivers, which has the potential to worsen congestion and increase fuel consumption. This research investigates the payoff between mobility and sustainability at urban signalised intersections via analytical and simulation study. The expected contribution of this research is to answer the following questions: "How does eco-driving affect traffic flow" and "how to efficiently eco-drive" in an urban area.
Traffic State Map based on Spatial-Temporal Relationship of Traffic Characteristics
This research aims to develop a traffic state map, which describes the traffic state for the entire urban network, including freeways and arterials. Instead of a conventional link-based analysis, an area-wide traffic state is investigated based on macroscopic traffic modelling techniques such as Macroscopic Fundamental Diagram (MFD) in order to explore the spatial-temporal traffic characteristics. The findings will provide a comprehensive understanding of congestion propagation, and is a novel method of monitoring the condition of network-wide traffic.

Environmental Adaptive and Cooperative Routing Protocol for Vehicular Ad-hoc Networks
This research aims to develop a cooperative and environmental adaptive routing protocol for vehicular ad-hoc networks. A cooperation method will be combined with a vehicular ad-hoc network routing protocol to enable more efficent and reliable routing. An environmental adaptive technique will be embedded into the same routing protocol using node cooperation as a metric. The protocol will be simulated using a realistic vehicle mobility model and a propagation model to obtain accurate results. It is expected that this routing protocol will support high service levels in infotainment and safety related applications for vehicular ad-hoc networks.

Short-term Bus Travel Time Prediction for Urban Networks
Bus travel time estimation could facilitate transit operators in offline management by optimising the transit schedule and understanding the reliablity of their systems. Bus travel time prediction, on the other hand, could be an important component of a real time traveller information system, and could also reduce anxiety and stress for travellers by helping them to select bus lines with minimum waiting time. This study is an effort to utilise the data of Brisbane's transit and traffic network in a bus travel time prediction model which considers the relationship between bus travel time and car travel time. The research goals are the comprehensive understandings on the bus operations and the relationship between bus and car travel time.

Comparison of Bus Rapid Transit (BRT) Operations between Local Route joins Corridor versus Local Route Interchange with Line Haul
The primary objective of this research is to study a line haul superbus system proposed for the study corridor, which uses 25m superbuses of nominal 200 passenger carrying capacity. This operational strategy would be intended to increase service capacity and reliablity. The approach includes investigating the feasibility of converting the existing busway operation to a line haul superbus system. The research will contribute to a better understanding of the impact of different operating strategies on BRT systems through performance measures including capacity and reliablity. This in turn will ultimately save time and expense for both passengers and transit agencies.
Communication Based Assistant System for Cooperative Merging on Urban Freeway
The aim of this research is to develop an available merging assistant to solve the problem of congestion caused by merging behaviour on an urban freeway. Merging management and a communication solution such as IEEE 802.11p AND IEEE 1609.3 are two parts that are included in this proposed system. Additionally, the research refers to a number of simulation tools, such as NS2, Matlab and Simulink. The results will provide a smooth merging process and a friendly driving environment during peak time on short-gap highway conditions.
Real-time Traffic Crash Propensity Analysis in Urban Motorways Using Data Mining Techniques
Much research has been conducted on traffic safety focusing on non-real-time crash prediction in the last decade. These studies applied aggregated data to analyse traffic risk indicators. However, due to the recent progress in IT and ITS, online traffic data is available and has made it possible to perform real-time proactive road safety studies. Although some research has been done in the scope of real-time traffic safety, it is still a fresh area of research. This study deals with crashes that have been caused mainly by hazardous traffic conditions. The study considers the variables between crash and traffic flow in developing the real-time crash estimation models. The research concentrates primarily on real-time crash propensity analysis in motorways using both descriptive and predictive techniques of data mining to maximise road safety.
Dyanmic OD matrices estimation from Bluetooth data
Origin-destination matrices are a major input for describing the demand in a transport networks. Being the corner stone of traffic planning and management, their precise knowledge is a major challenge. The aim of this research is to give a comprehensive overview of the main issues that need to be accounted for, prior to estimating Origin-Destination matrices in urban road networks.
Furthermore, we will propose a methodology that can be followed, in order to cleanse, correct and aggregate Bluetooth data, thus facilitating the OD pattern analysis.

Exploiting Bluetooth to estimate urban travel time
This research focuses on the capturing of MAC address from Bluetooth devices as an accurate and cost effective monitoring system for traffic data collection, especially in travel time estimation. Furthermore, new methods will be investigated to improve the amount of accurate travel time data and decrease the error in collected data when compared to other sources of travel time data.

Development of Enhanced VSL Deactivation Strategy
This research will develop a VSL deactivation scheme to improve the current practice of VSL operation. Essentially, the current VSL system induces an increase in travel time while providing safety benefits on the motorway. These operations decrease the network productivity and increase the travel time, mainly due to the delay in restoring the default speed limit in the traffic recovery phase. Therefore, this research will identify the possible solutions for reducing the negative impact of the current VSL system while maintaining its safety application.
Variable Speed Limit Speed Compliance and Flow Capacity Impact
Variable Speed Limit (VSL) is traditionally designed to improve safety, but recent research aims to employ VSL to increase throughput by optimising the use of available capacity. Such VSL implementations require high level of driver compliance to ensure VSL's optimum benefit is achieved. Recognising that high level of compliance is difficult to achieve in a real-life situation, this research focuses on analysing driver's reaction to VSL in order to improve VSL control strategy for future implementation.
Improving the Performance of Wireless Device Scanning Systems for Traffic and Crowd Data Acquisition Purposes
Wireless Scanners such as Bluetooth and Wi-Fi detectors have become popular in the area of traffic data acquisition, particularly for the travel time estimation purposes. This research aims to improve the performance of wireless scanning devices in terms of detection rate and sensitivity. The effective strategies and parameters impacting on the performance of wireless scanning systems will be investigated and studied along this project. The outcomes will be helpful to increase the efficiency of the wireless data collection process.
