Analysis of Urban Built Environment Impacts on Outdoor Physical Activities: A Case Study in China

Outdoor physical activities can promote public health and they are largely influenced by the built environment in different urban settings. Understanding the association between outdoor physical activities and the built environment is important for promoting a high quality of life. Existing studies typically focus on one type of outdoor activity...

Intercity truck route choices incorporating toll road alternatives using enhanced GPS data

This research presents the data collection, specification and estimation of a route choice model for intercity truck trips, with a focus on toll road usage. The data was obtained from driver-validated and enhanced GPS records. A mixed logit model with a path-size factor is specified. It accounts for heterogeneity among drivers using...

Evaluating urban neighbourhoods in terms of mobility performances, using open data and GPS tracks to assess actual people travel behaviour

Managing urban areas has become one of the most important development challenges of the 21st century. Building sustainable cities is a major factor nowadays. In this context, the advent of technologies such as GPS (Global Positioning System) and GIS (Geographical Information Systems) enables to better address the relationship between urban form...

Assessing people travel behavior using GPS and open data to validate neighbourhoods characteristics

With the help of technologies such as GPS tracks, GIS and open data is now possible to study people travel behaviour in a new way. Nowadays, large datasets can be easily handled thanks to databases and better visualized using GIS. Moreover, the availability of GPS data, open data and VGI makes accessible a lot of new information, which was not...

What is an Appropriate Temporal Sampling Rate to Record Floating Car Data with a GPS?

Floating car data (FCD) recorded with the Global Positioning System (GPS) are an important data source for traffic research. However, FCD are subject to error, which can relate either to the accuracy of the recordings (measurement error) or to the temporal rate at which the data are sampled (interpolation error). Both errors affect movement...

Analysis of Urban Space Networks for Recreational Purposes based on Mobile Sports Tracking Application Data

Even though studies of the built environment’s impact on citizens’ physical activity have become an aspiring topic in the recent years, up to now the most investigated topic is transport-related walking or cycling. However, little is known about the patterns of leisure-related physically active travels. One of the reasons behind this lack of...

Transportation mode-based segmentation and classification of movement trajectories

The knowledge of the transportation mode used by humans (e. g. bicycle, on foot, car, and train) is critical for travel behaviour research, transport planning and traffic management. Nowadays, new technologies such as the GPS have replaced traditional survey methods (paper diaries, telephone) since they are more accurate and problems such as...

Time use and movement behaviour of young people in cities: The application of GPS tracking in tracing movement pattern of young people for a week in Aalborg

Automatic segmentation and classification of movement trajectories for transportation modes

Automatic segmentation and classification of movement trajectories for transportation modes

The knowledge of the transportation mode used in a movement trajectory (derived in form of timestamped positions) is critical for applications such as travel behaviour studies. This thesis presents a method for segmenting movement data into single-mode segments and their classification with respect to the used transportation mode. The method...
