A Guide for Creating Visualizations and Evaluating Their Effectiveness


Funding

$400,000

Research Period

24 months

Description

There is a rich body of research in NCHRP 226, Vizguide, and NCHRP Project 20-24(93)B(02), Communicating Performance Management, and NCHRP Synthesis 52-16, Visualization of Highway Performance Measures, documented the range of practices state DOTs are currently using regarding their visualization of performance measures. The goal of this research would be to evaluate the noteworthy practices currently being pioneered by state DOTs using the foundation of these previous NCHRP projects and then develop an easy-to-use guide to creating effective visualizations.
NCHRP Synthesis 52-16, Visualization of Highway Performance Measures, found that there is little guidance or widely shared practices on how to evaluate a visualization’s effectiveness using a systematic process. This finding illuminated a need to implement a clear set of principles that can be used to evaluate visualizations that are used internally and externally. This evaluation guide would cover two distinct objectives – the effectiveness of the visualization is communicating information and the effectiveness of the visualization is changing behavior.
Even though the depth of information presented in many of the visualizations provided to the general public presents a sophisticated view of vast amounts of information, it does not yet provide a complete solution. Even with clear visualizations providing insight to solutions that could solve vexing problems (e.g., the effectiveness of wearing seat belts or not texting), there are still a significant number of people who don’t respond to the data and are killed in crashes they may have survived if they chose to buckle up or not text while they drive. Determining the means to evaluate the effectiveness of visualizations, not only to provide information, but to influence behavior would significantly enhance the value and the time and effort spent creating the visualizations.


Literature Search Summary

This research will build and expand upon research conducted under NCHRP 226, Vizguide, NCHRP Project 20-24(93)B(02), Communicating Performance Management, and NCHRP Synthesis 52-16, Visualization of Highway Performance Measures.


Objectives

Create a Guide that provides noteworthy practices to creating visualizations and evaluating their effectiveness.


Urgency and Potential Benefits

A clear takeaway from NCHRP Synthesis 52-16 is the potential power data visualization has to dramatically improve the safety and efficiency of the transportation system. What was also clear from this synthesis is the amount of time and expertise state DOTs have invested in developing visualizations for performance measures and to communicate the results effectively.
This guide would build on and evolve prior work by developing clear guidance on how to create effective visualizations and how to determine their effectiveness. It will enable states to most effectively capitalize and focus the investment, time and expertise they are currently deploying. It will provide a roadmap to the states who are in the early development of their visualization efforts and will provide an opportunity for well-established programs to expand their efforts by evaluating the effectiveness of their visualizations. Further, combining these two functions, the creation of effective visualizations with the evaluation of their effectiveness, creates the feedback loop that enables and promotes continuous improvement.


Implementation Considerations

Showcase the guide at the annual TRB meeting thru the AED80 Committee. Market the guide via the relevant AASHTO Committees [insert them here – system performance.] Explore promoting the guide through FHWA’s Innovation Programs and through their Transportation Performance Management (TPM) website. Explore promoting the guide via the Local Technical Assistance Program (LTAP) and potentially present at the annual NLTAPA meeting. Follow-up the publication of the guide with an implementation project to demonstrate its effectiveness and expand its reach.
