Dynamic activity-travel diary data collection using a GPS-enabled personal digital assistant
نویسندگان
چکیده
Activity-based transportation models have set the standard for modelling travel demand for the last decade. It seems common practice nowadays to collect the data to estimate these activity-based transportation models by means of activitytravel diaries. This paper presents a general functional framework of an advanced activity-travel diary data collection application to be deployed on a GPS-enabled personal digital assistant (PDA). The different modules, which are the building blocks of the application, will be scrutinized as well.

Exploring the potentials of automatically collected GPS data for travel behaviour analysis – A Swedish data source
Understanding the regularity and the variability of individual travel behaviour over time has been one of the key issues in travel behaviour research for three decades. A deeper insight into the long-term mobility patterns of persons and households has been so far restricted by the limited availability of longitudinal data, though. This paper presents an innovative approach to gain longitudinal...
متن کاملModeling Travel and Activity Routines using Hybrid Dynamic Mixed Networks
This paper describes a method for storing, modeling, and processing an individual’s travel history collected with a GPS enabled device. The technique uses a general framework called Hybrid Dynamic Mixed Networks (HDMNs), which are Hybrid Dynamic Bayesian Networks that allow representation of discrete deterministic information in the form of constraints. We use this framework to model a person’s...
متن کاملUsing GPS-enabled cell phones to track the travel patterns of adolescents
BACKGROUND Few tools exist to directly measure the microsocial and physical environments of adolescents in circumstances where participatory observation is not practical or ethical. Yet measuring these environments is important as they are significantly associated with adolescent health-risk. For example, health-related behaviors such as cigarette smoking often occur in specific places where sm...
متن کاملSummarizing GPS trajectories by salient patterns
Individuals can easily record their movements in space nowadays with personal navigation devices based on the GPS technology. The recorded data contain in principle detailed information about a traveled route. The information inherent in the data could be used to automatically generate travel diaries. In this paper we study a method to summarize and to symbolize a route according to the cardina...
متن کاملUsing Global Positioning Systems (GPS) and temperature data to generate time-activity classifications for estimating personal exposure in air monitoring studies: an automated method
BACKGROUND Personal exposure studies of air pollution generally use self-reported diaries to capture individuals' time-activity data. Enhancements in the accuracy, size, memory and battery life of personal Global Positioning Systems (GPS) units have allowed for higher resolution tracking of study participants' locations. Improved time-activity classifications combined with personal continuous a...
