Capturing travel entities to facilitate travel behaviour analysis : A case study on generating travel diaries from trajectories fused with accelerometer readings

Prelipcean, Adrian Corneliu January 2016 (has links)
The increase in population, accompanied by an increase in the availability of travel opportunities have kindled the interest in understanding how people make use of the space around them and their opportunities. Understanding the travel behaviour of individuals and groups is difficult because of two main factors: the travel behaviour's wide coverage, which encompasses different research areas, all of which model different aspects of travel behaviour, and the difficulty of obtaining travel diaries from large groups of respondents, which is imperative for analysing travel behaviour and patterns. A travel diary allows an individual to describe how she performed her activities by specifying the destinations, purposes and travel modes occurring during a predefined period of time. Travel diaries are usually collected during a large-scale survey, but recent developments show that travel diaries have important drawbacks such as the collection bias and the decreasing response rate. This led to a surge of studies that try to complement or replace the traditional declaration-based travel diary collection with methods that extract travel diary specific information from trajectories and auxiliary datasets. With the automation of travel diary generation in sight, this thesis presents a suitable method for collecting data for travel diary automation (Paper I), a framework to compare multiple travel diary collection systems (Paper II), a set of relevant metrics for measuring the performance of travel mode segmentation methods (Paper III), and applies these concepts during different case studies (Paper IV). / <p>QC 20160525</p>

Travel Adaptive Capacity Assessment Simulation (TACA Sim)

Watcharasukarn, Montira January 2010 (has links)
More than 95% of fuel used for personal transportation is petroleum-based (Environment and Development Division (EDD), 2005). The peak and decline of world oil production is producing price and uncertainty pressures that may cause significant travel behaviour change in the future. Current travel behaviour has developed during conditions of low cost fuel and government investment in private vehicle mobility. Current urban forms and land use have also been developed during a period of growth in vehicle travel demand. Research that explores the long term (permanent oil supply reduction period) implications of reduced fuel demand on private travel behaviour is needed. Local and national government investments in transport infrastructure and urban development will be used and require maintenance for decades. Research is needed to assess long-term mode choice and car travel demand as a function of urban form and demographic indicators. This type of travel behaviour adaptive potential should be relevant to transport planning decision making. Literature review shows that there are a few available long-term planning methods, models, or tools in transportation engineering for future oil depletion. Transportation engineers need information of how current travel demand patterns may change over the lifetime of infrastructure investments in response to oil supply depletion. Behaviour change data for long term future situations would be difficult to obtain using traditional survey methods because most people have never experienced oil depletion situations. This research proposes that immersing people into the situation of oil depletion through sharp price rise would be necessary to generate relevant behaviour change decisions. The thesis is that the long term behaviour change can be assessed by characterising current adaptive capacity. Adaptive capacity is defined in this thesis as the travel demand pattern with maximum fuel reduction without reducing participation in activities. The reasons why people might change travel demand to reduce fuel use is not part of the definition. This research also proposed that an immersive sim game environment could be used to prompt behaviour change decisions relating to fuel price shocks. Research into sim game surveys and travel behaviour surveys was used to inform the design of a Transport Adaptive Capacity Assessment (TACA) Sim survey tool. The TACA Sim survey was designed to assess capacity to adapt travel behaviour to reduce fuel use, and to characterise the potential for mode change. Participants experience the TACA Sim survey as a self assessment or transport energy audit. The survey provides a personal feel, focuses on the usual weekly activities, and provides feedback to participants about their fuel use and car dependence. Participants supply their normal travel activities over a week, and three weeks of sim play includes a steep fuel price rise while people are allowed to change their travel behaviour in response. The TACA Sim survey was evaluated through a case study of surveys of staff and students at the University of Canterbury. A second version of the TACA survey was developed that surveyed the one week of normal travel, but then probed adaptive capacity by asking a simple question after each travel activity was entered “Could you get to the activity another way?” The sim game travel adaptive capacity is compared with the available alternative adaptive behaviour for participants in a case study at the University of Canterbury. The results of the case study show that the participants responded well with the simulated situation. This reflects that the TACA Sim is successful in helping participants to perceive the situation of fuel price rise and think about their alternatives to car travel. Asking people “Could you get to the activity another way?” was found to effectively probe their adaptive capacity which agreed well with the virtual reality survey. The virtual reality survey yields more details of what people can do such as moving house, chaining trips, combining trips and buying a more efficient vehicle. The web-based TACA survey has been developed and deployed in two further research projects.

Poslední lancknecht a faccioso (Reflexe Španělska během první karlistické války v cestovním deníku Bedřicha ze Schwanzenbergu) / Last Lancknecht and faccioso (Reflection of Spain during the First Carlist War in the travel diary by Bedřich zu Schwanzenberg)

JÁROVÁ, Eva January 2007 (has links)
The aim of my master diploma work is the analysis of travel diary by Bedřich zu Schwanzenberg nicknamed "The Last Lancknecht" who fought in the First Carlist War in Spain. This master diploma work represents a contribution to the history of mentality in the thirties of the 19th century. The first part of my study is dedicated to the description of Bedřich zu Schwanzenberg´s adventurous life as well as to the political, economic situation in Spain and history of the Carlist Wars on the Iberian Peninsula. The notable part of the first part of my master diploma work is Bedřich zu Schwanzenberg´s individual reflexion of the First Carlist War. The following chapters deal with the European in particular German and Austrian oficcers´ such as Felix Lichnowsky, Wilhelm von Rahden, Adolf Loning and August Karl von Goeben participation in the First Carlist War and confrontation of their interesting witnesses of Spain with the travel diary by Schwanzenberg .

Understanding Individuals' Learning and Decision Processes in a Changing Environment by Using Panel Data

Ahmad Termida, Nursitihazlin January 2017 (has links)
When a new transport service is introduced, people have to learn and familiarize themselves with the new service before they decide to adopt it. These processes are developed over time, thus produce dynamics in individuals’ behavioural responses towards the service. This affects the demand of the new service, thus affect revenues. Available studies have examined the factors influencing these responses from microeconomic perspectives. The influence of the theory-based subjective factors has not been examined empirically. Understanding these would assist transport and urban planners to design a better marketing strategy to increase the market share of the new service. A change in seasons affect individuals’ activity-travel decisions, thus produce dynamics in activitytravel patterns in different seasons. Individuals’ constraints, in a form of mandatory activities (working/studying), are influencing individuals’ decisions to participate in day-to-day nonmandatory activities (leisure and routine activities). The interdependency between travel demand, time allocation and mode choice that considers interactions between mandatory and non-mandatory activities, in different seasons is less explored. Understanding these would assist transport planners and operators to manage travel demand strategies across different seasons of the year and provide better transportation systems for all individuals. This thesis includes five papers. Paper I explores individuals’ characteristics of the quick-response and the adopters of the new public transport (PT) service and examines the temporal effects. Paper II investigates the subjective factors influencing a quick-response to the new PT service by proposing a modified attitude-behaviour framework. Paper III and IV analyse the effects of seasonal variations and individuals’ constraints on their day-to-day activity-travel decisions and patterns. Paper V analyses the attrition and fatigue in the two-week travel diary panel survey instrument. / <p>QC 20170323</p>
