Arterial travel time estimation : revisiting the classical procedure

Travel time is an important network performance measure and it quantifies congestion in a manner easily understood by all transport users. In urban networks, travel time estimation is challenging due to number of reasons such as, fluctuations in traffic flow due to traffic signals, significant flow to/from mid link sinks/sources, etc. The classical analytical procedure utilizes cumulative plots at upstream and downstream locations for estimating travel time between the two locations. In this paper, we discuss about the issues and challenges with classical analytical procedure such as its vulnerability to non conservation of flow between the two locations. The complexity with respect to exit movement specific travel time is discussed. Recently, we have developed a methodology utilising classical procedure to estimate average travel time and its statistic on urban links (Bhaskar, Chung et al. 2010). Where, detector, signal and probe vehicle data is fused. In this paper we extend the methodology for route travel time estimation and test its performance using simulation. The originality is defining cumulative plots for each exit turning movement utilising historical database which is self updated after each estimation. The performance is also compared with a method solely based on probe (Probe-only). The performance of the proposed methodology has been found insensitive to different route flow, with average accuracy of more than 94% given a probe per estimation interval which is more than 5% increment in accuracy with respect to Probe-only method.

Journeys to health services in Great Britain : an analysis of changing travel patterns 1985-2006

This paper examines changing patterns in the utilisation and geographic access to health services in Great Britain using National Travel Survey data (1985-2006). The utilisation rate was derived using the proportion of journeys made to access health services. Geographic access was analysed by separating the concept into its accessibility and mobility dimensions. Regression analyses were conducted to investigate the differences between different socio-spatial groups in these indicators over the period 1985-2006. This study found that journey distances to health facilities were significantly shorter and also gradually reduced over the period in question for Londoners, females, those without a car or on low incomes, and older people. However, most of their rates of utilisation of health services were found to be significantly lower because their journey times were significantly longer and also gradually increased over the periods. These findings indicate that the rate of utilisation of health services largely depends on mobility level although previous research studies have traditionally overlooked the mobility dimension.

Awakening the spirit : telling the stories

Stephen Page talking with Cheryl Stock Stephen Page is one of the most significant dance artists working in Australia today, unique in his ability to forge and sustain a company of Indigenous artists through his seminal leadership of Bangarra Dance Theatre, which celebrated its 20 year anniversary in 2009. Together with the many artists who have contributed to the Bangarra vision, Stephen has created a distinctive contemporary Indigenous dance style and approach, celebrated for the stories it tells of the Aboriginal and Torres Strait Islander experience. Fusing the traditional with the contemporary through a connection to the spirit of the land and its people, Stephen has inspired and influenced a generation of Aboriginal and Torres Strait Islander dance and theatre artists as a choreographer, director and mentor. His down to earth humour, his passion and his sensitivity draw us as audience, Indigenous and non-Indigenous alike, to his theatrical stories of place and spirit – both ancient and modern – in ways that simultaneously transcend and reaffirm the particular cultural experience which informs them. This conversation covers the early years of growing up with his 'urban clan', discovering dance and politics and his spiritual awakening at Yirrkala. Stephen then describes moving in and out of different realities as a member of Sydney Dance Company whilst simultaneously exploring his Indigenous dance voice, the transition from dancer to choreographer, creating the Bangarra identity and the intercultural experiment of 'Rites' with the Australian Ballet. The last section looks at his various roles as an artistic director and nurturing the next generation of Indigenous artists.

Building engaged, sustainable online communities : a case study of an adventure travel website

This paper will provide an overview of a join research initiative being developed by the Queensland University of Technology in conjunction with the Australian Smart Services Cooperative Research Centre in relation to the development and analysis of online communities. The intention of this project is to initially create an exciting and innovative web space around the concept of adventure travel and then to analyse the level of user engagement to uncover possible patterns and processes that could be used in the future development of other virtual online communities. Travel websites are not a new concept and there are many successful examples currently operating and generating profit. The intention of the QUT/Smart Services CRC project is to analyse the site metrics to determine the following: what specific conditions/parameters are required to foster a growing and engaged virtual community; when does the shift occur from external moderation to a more sustainable system of self-moderation within the online community; when do users begin to take ownership of a site and take an invested interested in the content and growth of an online community; and how to retain active contributors and high-impact power users on a long-term basis. With the travel website rapidly approaching release, this paper begins the process of reflection, outlining the process undertaken and the findings so far aggregated whilst also positioning the project within the greater context of current online user participation and user generated content research.

Identifying parent perspectives to guide active travel intervention with small populations : case study in Denver, Colorado

This paper investigates a strategy for guiding school-based active travel intervention. School-based active travel programs address the travel behaviors and perceptions of small target populations (i.e., at individual schools) so they can encourage people to walk or bike. Thus, planners need to know as much as possible about the behaviors and perceptions of their target populations. However, existing strategies for modeling travel behavior and segmenting audiences typically work with larger populations and may not capture the attitudinal diversity of smaller groups. This case study used Q technique to identify salient travel-related attitude types among parents at an elementary school in Denver, Colorado; 161 parents presented their perspectives about school travel by rank-ordering 36 statements from strongly disagree to strongly agree in a normalized distribution, single centered around no opinion. Thirty-nine respondents' cases were selected for case-wise cluster analysis in SPSS according to criteria that made them most likely to walk: proximity to school, grade, and bus service. Analysis revealed five core perspectives that were then correlated with the larger respondent pool: optimistic walkers, fair-weather walkers, drivers of necessity, determined drivers, and fence sitters. Core perspectives are presented—characterized by parents' opinions, personal characteristics, and reported travel behaviors—and recommendations are made for possible intervention approaches. The study concludes that Q technique provides a fine-grained assessment of travel behavior for small populations, which would benefit small-scale behavioral interventions

Analysis for the use of cumulative plots for travel time estimation on signalized network

This paper provides fundamental understanding for the use of cumulative plots for travel time estimation on signalized urban networks. Analytical modeling is performed to generate cumulative plots based on the availability of data: a) Case-D, for detector data only; b) Case-DS, for detector data and signal timings; and c) Case-DSS, for detector data, signal timings and saturation flow rate. The empirical study and sensitivity analysis based on simulation experiments have observed the consistency in performance for Case-DS and Case-DSS, whereas, for Case-D the performance is inconsistent. Case-D is sensitive to detection interval and signal timings within the interval. When detection interval is integral multiple of signal cycle then it has low accuracy and low reliability. Whereas, for detection interval around 1.5 times signal cycle both accuracy and reliability are high.

Five senses digital stories

These digital stories were produced during a commercial research project with SLQ and Flying Arts. The works build on the research of Klaebe and Burgess related to variable workshop scenarios, and the institutional contexts of co-creative media. In this instance, research focused on the distributed digital storytelling workshop model; and the development of audiences for digital storytelling. The research team worked with regional artists whose work had been selected for inclusion in the Five Senses exhibition held at the State Library of Queensland to produce stories about their work; these works were then in turn integrated into the physical exhibition space. Location remoteness and timeline were factors in how the stories were made in a mix of individual meetings and remote correspondence (email &phone).

From barrier elimination to barrier negotiation : a qualitative study of parents' attitudes about active travel for elementary school trips

This paper examines parents' responses to key factors associated with mode choices for school trips. The research was conducted with parents of elementary school students in Denver Colorado as part of a larger investigation of school travel. School-based active travel programs aim to encourage students to walk or bike to school more frequently. To that end, planning research has identified an array of factors associated with parents' decisions to drive children to school. Many findings are interpreted as ‘barriers’ to active travel, implying that parents have similar objectives with respect to travel mode choices and that parents respond similarly and consistently to external conditions. While the conclusions are appropriate in forecasting demand and mode share with large populations, they are generally too coarse for programs that aim to influence travel behavior with individuals and small groups. This research uses content analysis of interview transcripts to examine the contexts of factors associated with parents' mode choices for trips to and from elementary school. Short, semi-structured interviews were conducted with 65 parents from 12 Denver Public Elementary Schools that had been selected to receive 2007–08 Safe Routes to School non-infrastructure grants. Transcripts were analyzed using Nvivo 8.0 to find out how parents respond to selected factors that are often described in planning literature as ‘barriers’ to active travel. Two contrasting themes emerged from the analysis: barrier elimination and barrier negotiation. Regular active travel appears to diminish parents' perceptions of barriers so that negotiation becomes second nature. Findings from this study suggest that intervention should build capacity and inclination in order to increase rates of active travel.

Queensland Business Women Stories

These projects build on the research of Klaebe and Burgess into digital story-telling, specifically variable workshop scenarios, co-creative media, participatory public history, and the development of co-creative production processes for cultural institutions. The projects represented a partnership between QUT and the State Library of Queensland. The Five Senses project focused on the distributed digital storytelling workshop model and the development of audiences for digital storytelling. The team worked with regional artists whose work had been selected for inclusion in the Five Senses exhibition at the State Library of Queensland to produce stories about their work; these works were then integrated into the physical exhibition space. The Queensland Businesswomen project produced four digital stories profiling the lives of leading Queensland businesswomen. The digital story telling workshop model was disbanded and research teams worked individually with participants to create the digital stories. Academic research and oral history interviews were conducted initially to foreground these productions. This pilot led to a larger project, Business Leaders Hall of Fame, which now has a dedicated viewing room in the SLQ sponsored by an annual silver service dinner event. With the Responses to the Apology project, which stimulated similar projects in Mt Isa and Cairns, the research team worked with Indigenous facilitators, and the participants created their digital stories with assistance from these facilitators and the QUT research team using a mix of workshop and individual meetings. The research component of the work relates to the further development of co-creative production processes for cultural institutions, involving a wide range of institutional and individual partners, while authentically representing the intensely personal perspectives of each of the primary participants. The Queensland Business Leaders Hall of Fame was a research project that included interviews with eminent Queenslanders that produced oral history interviews and digital stories about the achievements of both Queensland personalities and businesses. This model was able to test and evaluate the use of oral history and digital storytelling for learning and community heritage purposes. Interviewees include; Sir John and Valmai Pidgeon, Joseph Saragossi, Robert Bryan, Clem Jones, Jim Kennedy, Sr Angela Mary, Castelmaine Perkins, Burns and Philp, Qantas, Don Argus & Steve Irwin All digital stories, oral history interviews and transcripts were accessioned into the library collection – an international first for digital stories. Two publications in refereed journals have resulted, and the digital stories are stored in the SLQ permanent collection for the benefit of national and international scholars and the general public.

Conference report: Lights, Camera, Action : Spotlight on Tourism in the New Millennium. 31st Annual Travel and Tourism Research Association Conference.

The 31st TTRA conference was held in California’s San Fernando Valley, home of Hollywood and Burbank’s movie and television studios. The twin themes of Hollywood and the new Millennium promised and delivered “something old, yet something new”. The meeting offered a historical summary, not only of the year in review but also of many features of travel research since the first literature in the field appeared in the 1970s. Also, the millennium theme set the scene for some stimulating and forward thinking discussions. The Hollywood location offered an opportunity to ponder on the value of the movie-induced tourism for Los Angeles, at a time when Hollywood Boulevard was in the midst of a much needed redevelopment programme. Hollywood Chamber of Commerce speaker Oscar Arslanian acknowledged that the face of the famous district had become tired, and that its ability to continue to attract visitors in the future lay in redeveloping its past heritage. In line with the Hollywood theme a feature of the conference was a series of six special sessions with “Stars of Travel Research”. These sessions featured: Clare Gunn, Stanley Plog, Charles Gouldner, John Hunt, Brent Ritchie, Geoffrey Crouch, Peter Williams, Douglas Frechtling, Turgut Var, Robert Christie-Mill, and John Crotts. Delegates were indeed privileged to hear from many of the pioneers of tourism research. Clare Gunn, Charles Goeldner, Turgut Var and Stanley Plog, for example, traced the history of different aspects of the tourism literature, and in line with the millennium theme, offered some thought provoking discussion on the future challenges facing tourism. These included; the commodotisation of airlines and destinations, airport and traffic congestion, environment sustainability responsibility and the looming burst of the baby-boomer bubble. Included in the conference proceedings are four papers presented by five of the “Stars”. Brent Ritchie and Geoffrey Crouch discuss the critical success factors for destinations, Clare Gunn shares his concerns about tourism being a smokestack industry, Doug Frechtling provides forecasts of outbound travel from 20 countries, and Charles Gouldner, who has attended all 31 TTRA conferences, reflects on the changes that have taken place in tourism research over 35 years...

Benefits and issues of urban network travel time prediction

This paper presents the benefits and issues related to travel time prediction on urban network. Travel time information quantifies congestion and is perhaps the most important network performance measure. Travel time prediction has been an active area of research for the last five decades. The activities related to ITS have increased the attention of researchers for better and accurate real-time prediction of travel time. Majority of the literature on travel time prediction is applicable to freeways where, under non-incident conditions, traffic flow is not affected by external factors such as traffic control signals and opposing traffic flows. On urban environment the problem is more complicated due to conflicting areas (intersections), mid-link sources and sinks etc. and needs to be addressed.

Stories of cross-dressing and the body : family memories in fiction

Ruth Finnegan (2006, 179) describes how family myths have the power to provoke images that recur throughout generations. This paper will document my own encounter with such persistent images in the stories of a mother and daughter. Both mother and daughter told stories about encountering cross-dressing men in the streets of Brisbane, and both showed similar anxiety over their own body size. As a creative writer working with oral histories, I found these stories of the disguised body compelling. By drawing on the storytelling strategies and preoccupations present in the interview, I used imagination and fictional techniques to investigate the possibility of symbolic resonance of memories across generations. In her novel Beloved, Toni Morrison (1987) uses the notion of ‘rememory’ to describe how characters actively make and suppress meanings in their recollections. Like Morrison, my writing speaks to notions around the way stories are remembered and told.

Sourdough & other stories : a story told in parts (a mosaic novel and exegesis)

The mosaic novel - with its independent 'story-tiles' linking together to form a complete narrative - has the potential to act as a reflection on the periodic resurfacing of unconscious memories in the conscious lives of fictional characters. This project is an exploration of the mosaic text as a fictional analogue of involuntary memory. These concepts are investigated as they appear in traditional fairy tales and engaged with in this thesis's creative component, Sourdough and Other Stories (approximately 80,000 words), a mosaic novel comprising sixteen interconnected 'story-tiles'. Traditional fairy tales are non-reflective and conducive to forgetting (i.e. anti-memory); fairy tale characters are frequently portrayed as psychologically two-dimensional, in that there is no examination of the mental and emotional distress caused when children are stolen/ abandoned/ lost and when adults are exiled. Sourdough and Other Stories is a creative examination of, and attempted to remedy, this lack of psychological depth. This creative work is at once something more than a short story collection, and something that is not a traditional novel, but instead a culmination of two modes of writing. It employs the fairy tale form to explore James' 'thorns in the spirit' (1898, p.199) in fiction; the anxiety caused by separation from familial and community groups. The exegesis, A Story Told in Parts - Sourdough and Other Stories is a critical essay (approximately 20,000 words in length), a companion piece to the mosaic novel, which analyses how my research question proceeded from my creative work, and considers the theoretical underpinnings of the creative work and how it enacts the research question: 'Can a writer use the structural possibilities of the mosaic text to create a fictional work that is an analogue of an involuntary memory?' The cumulative effect of the creative and exegetical works should be that of a dialogue between the two components - each text informing the other and providing alternate but complementary lenses with which to view the research question.

Creating Institutions: Linking the Local and the Global in the Travel of Crime Policies

Institutions represent the ‘technologies of the social.’ They are increasingly modelled and transported to other cultures and societies, and criminal justice institutions—traditional, parochial, and local as they are—are no exception to this. Problems of crime and insecurity have engendered the travelling of institutions from the centre to the periphery and vice versa. This paper will explore the problems which arise from travelling and modelling, and from the transport and creation of institutions in the area of criminal justice. An important feature in the travel of criminal justice institutions is the use of ‘local knowledge’ and its role in this process.
