RDE DATA VISUALIZATION

Visualizing the Research Data Environment

The US Federal Highway Administration's Research Data Environment (RDE) contains a vast amount of collected, measured, and simulated data about the highway systems of the United States. This website contains six prototype visualization elements that explore the depth and breadth of the data in the RDE.

Using this website

Navigate between the prototype visualization elements using the menu at the top of the page. This website is optimized for use on a desktop or laptop computer, using Google Chrome.

Overview of the visualization elements

Element 1: Integration

The Pasadena data environment in the RDE contains road-link level simulated traffic data for a period of several months in 2011. The visualization shows simulated traffic for the 24-hour period of October 1st, 2011, around a busy part of town.

Element 1 requires a web browser that renders WebGL. If you are unable to interact with the visualization, you can view a video of it in action at this link.

Element 2: Communication

The Federal Highway Administration's Connected Vehicle Safety Pilot Program studies the utility and effectiveness of communicating safety data between vehicles and roadside equipment (RSE). The visualization focuses on a single RSE and plots the quality and quantity of data received by the equipment from vehicles with on-board devices capable of broadcasting safety data.

Element 3: Weather

The Federal Highway Administration also maintains the Weather Data Environment, known as the WxDE, which is a repository of traffic-related weather data that can be used in research. Visualization element 3 combines data from the WxDE with data from the Minnesota DOT Mobile Observation data environment, on the RDE, to show weather, movement of snowplows, and road conditions during a blizzard in February of 2014.

Element 4: Traffic Interventions

Multi-Modal Intelligent Traffic Signal Systems (MMITSS) is a technology that allows traffic signals to communicate with vehicles and possibly behave differently for different types of vehicles. For example, freight trucks may trigger traffic lights to turn green in an effort to reduce congestion. Element 4 provides an interactive interface for looking at the difference in traffic during a MMITSS field test in Anthem, Arizona.

Element 5: Exploration of the RDE

The RDE contains a variety of data environments totaling over 300 Gigabytes of compressed data. Element 5 is an interactive dashboard that allows users to explore the datasets available in the RDE. By filtering on attributes of the dataset, it is easy to narrow the list of 161 down to those matching your interests.

Element 6: Depth of Connected Vehicle Data

While visualization element 5 presents the depth of data available in the RDE, Element 6 presents a view into the breadth of data that is available in one of the many RDE data environments. Element 6 is an interactive visual overview of the Basic Safety Message data set in the Safety Pilot Model Deployment data enviroment that logs vehicles' attempts to communicate with roadside equipment, as also shown in Element 2.
