The aim of this thesis is to evaluate fatigue management systems (FMSs) within the Australian transportation industry, and provide directions for future improvement. In doing so, it draws on some preliminary data from the rail industry, and a larger study that evaluates several components of a FMS that was implemented by the Australian Civil Aviation Safety Authority (CASA) for the general aviation sector in 2000.

The more we search outside of ourselves for answers, the less likely we are to be satisfied. Often, however, the external journey brings us closer to who we are as we experience the peaks and troughs of human existence. Ultimately, it is happiness that we seek. The idea and pursuit of happiness is a universal theme and I believe this search for happiness is also a search for home. Whether it is a physical or spiritual place, many of us search for that centre but the answer lies in the journey, not the destination. Using the road trip as the vehicle for this search, I set out across the USA to connect with others who were on the same journey. I photographed people (who had moved from their birthplace for reasons such as love and better opportunities), and landscapes that evoke both home and the journey. The road trip can be an escape from home but also a search for it and so the resulting project became two distinct sections that weave and overlap.

The problem surrounding the ever-increasing toll of death and injury arising from road accidents is one which is receiving increasing attention as the number of vehicles on the road continues to rise. While it has not been possible to isolate any one factor as the sole or even primary cause of road accidents, several surveys have shown that in many accidents alcohol has been a contributory factor by affecting the faculties of the driver of pedestrian. The thesis then goes on to discuss factors causing individual differences in response to the same blood alcohol concentration and the correlation between impairment of driving and blood alcohol concentration.

<p>Road conditions affect fuel efficiency and vehicle fatigue when driving heavy trucks. Information about traveled road conditions enable optimization of chassis configuration when driving, and logging of vehicle stress. Previous work on this topic focus mainly on tuning of active suspension parameters in the car industry. One conceivable application for heavy trucks is implementation of active chassis level control based on road conditions, with possible improvements in driving economy as result. Another is logging of usage conditions which helps explain vehicle faults caused by abnormal wear. This work examines the possibilities to use already on vehicle sensors for road roughness estimation. It also investigates what requirements existing signals must fulfill to ensure reliable estimates. Two methods for road roughness estimation are proposed using rear axle level sensor and a simple linear suspension system model.</p>

<p>Road safety is a major issue affecting the road sector. Road accidents remain a serious impediment to sustainable human development in many of the developing member countries (DMCs) of the Asian Development Bank (ADB). Road accidents continue to be an important social and economic problem in developing countries like India. Growth in the number of motor vehicles, poor enforcement of traffic safety regulations, poor quality of roads and vehicles, and inadequate public health infrastructures are some of the road safety problems facing in India. </p><p>The object of this Thesis is to present a status report on the nature of the government policy towards the Activity plans implemented till now and which has to be implemented later for the reduction of road fatalities and for the safe roads, and also giving the guidelines for financing of remedial measures, institutional framework, physical characteristics of the road, traffic control and calming measures, road safety education and enforcement issues. </p><p>The aim of the Activity plans is to analyze the present situation of road safety in India and to indicate main problems in individual sector of the Activity implemented by comparing and taking the examples of some of the ASEAN Region who are successed in implementing in the individual sectors. The effect of the programme to real safety situation is estimated, and further plans could be corrected if it is necessary. Implementation of the goals for the coming years to reduce the number of accidents at maximum extent and give people, the safe and the steady flow of traffic in India. The vision of a tremendous change next 5 to 10 years is based on a big potential for improvement and a joint effort of all involved groups on all levels of traffic safety, centrally coordinated by the National Road Safety Authorities. </p><p>The Action Plan is deliberately divided into 14 key Sectors of activity in broadly the same way as the individual country road safety action plans. The sectors involve many different disciplines and a very wide range of multi sector activities but all are based on applying scientific, methodical approaches to the problem. At the end the thesis gives the recommendations and conclusion for the safe Roads in India</p>

<p>The Automated Manual Transmission system Opticruise is dependent on signals from sensors located in different parts of the Scania trucks. These signals are of different qualities and have different update frequencies. Some signals and quantities that are hard or impossible to measure are also of importance to this system.</p><p>In this thesis a driveline observer for the purpose of signal improvement is developed and estimations of unknown quantities such as road incline and mass of the vehicle are performed. The outputs of the observer are produced at a rate of 100 Hz, and include in addition to the mass and road incline also the speed of the engine, output shaft of the gearbox, wheel and the torsion in the driveline. Further the use of an accelerometer and the advantages gained from using it in the observer are investigated.</p><p>The outputs show an increased quality and much of the measurement noise is successfully removed without introducing any time delays. A simulation frequency of 100 Hz is possible, but some dependency toward the stiffness of the driveline is found. The observer manages to estimate the road slope accurately. With the use of an accelerometer the road slope estimation is further improved and a quickly converging mass estimation is obtained.</p>

<p><strong>Aim:</strong></p><p>The purpose of this study is to explore the Vietnamese market for Electronic Road Tolls. Company X is a world wide supplier of electronic toll systems. They are focusing on systems that will reduce traffic congestion in cities or congestion created by road charge toll systems. Company X has been active in the South East Asia for over 10 years. Now they want to explore new markets in this region. The company is interested in developing countries where road infrastructure is expanding. Since Vietnam is one of the fastest growing economies in Asia Company X is interested in if it is a market they should enter.</p><p> </p><p>Research questions: </p><p><em>Should Company X enter the Vietnamese market?</em></p><p><em>If yes, which entry strategy should be used entering this market?</em></p><p> </p><p><strong>Method:</strong></p><p>To analyze Company X’s internal and external environment I have used different theoretical methods, PEST analysis, Micro / Macro environmental analysis and with the SWOT framework I have summarized recommendations based on the facts I have gathered. I have also investigated different entry strategies to see what is most suitable for a Company X. I have collected data via interviews, literature and internet sources.</p><p> </p><p><strong>Result & Conclusions: </strong></p><p>Short term Company X has the opportunity to come in with their products into Vietnam with a co-operation with Competitor A. They will set up a test system at one toll plaza between the airport and Hanoi with two lane dedicated for EFC and Company X is their first choice if they are competitive. This will give them the opportunity to be first on this market to implement microwave equipment in Vietnam and an opportunity to set the standard in the country for the future. </p><p><strong>Suggestions for future research: </strong></p><p>The empirical data in this thesis is mainly gathered from secondary sources. The information would have been more accurate with more primary data.</p><p><strong> </strong></p><p><strong>Contribution of the thesis: </strong></p><p>This thesis shows that large investments in road infrastructure are coming up in Vietnam. This thesis also shows that currently there is low activity from competitors using the same technology and this was not previously known by Company X.</p>

This thesis presents an endeavor to design and construct a prototype of an automated road repair vehicle called the Intelligent Pothole Repair Vehicle (IPRV). The IPRV is capable of automatically detecting and filling potholes on road surfaces without operator assistance. An easy-to-construct mechanical means of pothole detection was employed to reduce costs and complexity that have thus far been the primary disadvantage of automated road repair vehicles. A network interface to an Ethernet was designed based on the transmission control protocol (TCP) to enable remote operability of the IPRV. A laptop computer was used onboard the IPRV for control and interfacing using a data-acquisition card installed on it. The Visual Basic® programming language and the Windows application programming interface (API) were used for all the programming requirements of this thesis. The IPRV employs feedback mechanisms for position control and path following. Operation has been designed to incorporate safety mechanisms that ensure that the IPRV automatically stops in the case of a loss of communication link or large network delays. Experiments were performed to test and calibrate the IPRV. The IPRV was designed to detect potholes that have a maximum depth greater than 2 cm.
