Estimating the presence of people in buildings using Call Detail Records
… time consuming, capital-intensive and infrequent travel surveys. While mechanisms have been proposed for reproducing particular characteristics of individual mobility, this is the first attempt to generate all mobility patterns at fine spatial and temporal scales at the level of individual …

Towards comfortable and walkable cities : spatially resolved outdoor thermal comfort analysis linked to travel survey-based human activity schedules
… clustering techniques applied to activity-based travel surveys. An office modeling case study is presented through extracted occupancy scenarios, to compare simulation accuracy against current practice standards. Finally, an assimilation of both workflows is presented to generate "Trip Comfort" …

Exploring privatisation as a panacea to the creation of value in South Africa's passenger rail service
… with various sources (e.g. National Household Travel Surveys 2003, 2013 and 2020) pointing to the service getting progressively worse with the passage of time. To reform passenger rail and change its fate, many governments around the world, beginning in the 1980s, implemented different forms of …

Deciphering human activities in complex urban systems : mining big data for sustainable urban future
… understanding of activity patterns and travel behavior presents a number of obstacles. This dissertation examines some of these obstacles and develops data processing pipelines and urban activity modeling techniques that can complement traditional travel surveys and facilitate the …

Mediating mobility at the school gate: interpreting London's School Street schemes
… for School Streets being to increase active travel to school, evidence for their effectiveness in changing travel behaviour lags their widespread adoption. Responding to this gap, the research has two primary aims. First, to understand the contribution of School Streets to children’s mobility …

Impacts of Automated Buses on Travel Mode Preference for Different Income Groups and Density Areas
… groups and density areas. The study analyzes travel surveys and then simulates the impact of ABs on travel-to-work mode choices. In particular, the research explores the mode preferences of residents in the Metro Boston Area based on the Massachusetts Travel Survey of 2011 and builds mode …

Understanding transit travel behavior : value added by smart cards
Travel behavior represents a particularly complex area of research in transportation given the interaction between transport supply characteristics and the user perceptions which guide his/her decisions. Thanks to the advent of automated data collection including smart cards, each customer …

A Transport Justice Evaluation of Employer-Based Transit Subsidies
… levels. I use worker-level data from household travel surveys for 10 of the 22 largest MPOs in the U.S., organized into 7 cases: 1) Atlanta; 2) Baltimore and Washington, DC; 3) Denver; 4) Los Angeles and San Diego; 5) New York and Newark; 6) Philadelphia; and 7) San Francisco. In each of the 7 …

Opportunities and challenges for shared micromobility planning : a case study of Austin dockless scooter-share program
… Research gaps exist in shared micromobility travel behavior for many reasons. First, it has been well integrated with other high-tech innovations such as smartphones and mobile payment. Thus, the travel data is passively collected from location-based devices rather than travel surveys. …

Non-motorised school travel planning: development, demonstration and evaluation of a 'walking bus' initiative at selected schools in Cape Town
… the impacts of a non- motorised school travel intervention in the local context. The literature review conducted situated the current interest in active travel modes in the context of concerns over declining child independent mobility. 'Walking buses' were identified as the most …

Investigation into the effects of non-motorised transport facility implementations and upgrades in urban South Africa
… Additionally, data from the National Household Travel Surveys (NHTS, 2003 and 2013) helped to determine the changes in the number of NMT trips on a provincial level, as well as within the case study and control areas within Cape Town. The last part of the research, used the information, of where …

An investigation of heterogeneous commuting mode choices through an Early Stopping Bayesian Data Assimilation approach
… to those observed today. The challenge for travel behaviour modellers is that in the existing travel surveys, such heterogeneity is hard to estimate due to their low presence in the data samples. This dissertation develops an Early Stopping Bayesian Data Assimilation (ESBDA) estimator which …

Bicycle Travel, Injury Risk and Conspicuity. Application of Epidemiological Methods
… economic benefits but is rarely part of everyday travel for many people. The real and perceived risk of injury is commonly cited as a significant deterrent to engaging in such activity and is sometimes associated with the danger of motorised traffic. Bicycle-motor vehicle collisions often result …
