PORTFOLIO
RITIS
The Regional Integrated Transportation Information System (RITIS) is an automated data sharing, dissemination, and archiving system that includes many performance measure, dashboard, and visual analytics tools that help agencies… Read more »
Sky Graph
As air traffic rises at a rapid rate, congestion in National Airspace (NAS) becomes a primary concern of Air Traffic Control (ATC). This increase in traffic is pushing the limits… Read more »
TreeVersity
Comparing Trees is difficult. To address this, we present TreeVersity a new interactive visualization that gives users powerful tools to detect both node value changes and topological differences. TreeVersity uses… Read more »
Explore and Visualize Crashes
Analyzing safety data to determine the cause of accidents and identify high-accident locations helps to improve road safety and reduce accident severity. Accident records contain a vast amount of information… Read more »
Detector Data Analysis
The Detector Explorer is a robust tool that makes the data recorded by traffic detectors easily understandable through a series of graphical reports, charts, and tables all exportable to Excel…. Read more »
Timeline
The Incident Timeline Tool provides for the visualization of detailed real-time and historic traffic management center incident data. Large incident data sets can be viewed in a graphical, one-screen overview. … Read more »
Clarus History Explorer
The CATT Lab has integrated all Clarus Data into their Regional Integrated Transportation Information System (RITIS) for real-time situational awareness and historical safety data analysis. RITIS is a data… Read more »
Time Spiral
Temporal data sets often present an interesting characteristic of being linear in nature, but contain cyclic patterns that are not effectively conveyed by conventional linear visualizations and are often more… Read more »
CHART Reporting
The CHART Reporting application allows managers and operations staff at the Maryland Department of Transportation’s Coordinated Highway Action Response Team (CHART) to quickly answer questions about their real-time and archived… Read more »
Incident Clustering Explorer
A novel, web-based, visual analytics tool called the Incident Cluster Explorer (ICE) was developed as an application that affords sophisticated yet user-friendly analysis of transportation incident datasets. Interactive maps, histograms,… Read more »
Arc Chart
When dealing with data sets containing hundreds of variables, it is often extremely difficult, if not impossible, to quickly discover important and significant relationships that exist among the various data… Read more »
Vehicle Probe Project Suite
The Vehicle Probe Project Suite allows agencies to support operations, planning, analysis, research, and performance measures generation using probe data mixed with other agency transportation data. The suite consists of… Read more »
Virtual Weigh Station
The CATT Lab has designed a series of applications for the State Highway Administration, Motor Carrier Division, to help them monitor their virtual weigh station (VWS) sites. Android and iOS… Read more »
Virtual Incident Management Training
Training of traffic control personnel, emergency management personnel, and first-responders is a critical element in effectively managing the consequences of road construction, traffic incidents, natural disasters, acts of terrorism, and… Read more »
Incident Management Core Competencies
There is inherent risk of secondary accidents in an incident management. In order to minimize the risk, responders from across disciplines need to know how to efficiently make themself safe,… Read more »
4D Virtual Globe
The advancement of automated data reporting technologies has supplied us with virtually boundless real-time geospatial information. It is becoming more common now for public and private sectors to provide access… Read more »
