Visualizing Travel Patterns Using Passive Data
Using data analysis and interactive reporting/presentation techniques in R, Python, and Jupyter Notebooks, the team is able to relay results from analyses quickly as projects progress. The team has also developed a number of skills for visualizing origin-destination characteristics and travel patterns from passive data and roadway networks, including interactive graphics (MAG External Travel Study)…
Emerging Data and Methods
Understanding Bias Emerging big data sources unlike traditional surveys come with their own biases, which could be distinct across space, time and socio-demographics. This is because, these data sources are more of a convenience sample heavily influenced by the purpose of software application generating it, from which it is derived. Thus, it makes them more…
National Performance Management Research Data Set
The FHWA has acquired a national data set (called NPMRDS) of average travel times on the National Highway System for use in its performance measures and management activities. TTI is a part of the NPMRDS project team and provides geospatial data integration (i.e., GIS conflation) services. In particular, TTI conflates selected HPMS attributes onto the…
Pedestrian and Bicyclist Research
