Your Use Cases

[schnuerle]

Leave comments here on some use cases you'd like to see supported by this project.

If you've got a fleshed out idea, create a new issue for it and label it Use Case for others to take a look at.

We'll consolidate and get the best ones onto the Roadmap.

Crashes on Camera

Preserve video footage of crashes that occur within a viewshed of traffic cameras

At the City of Sandy Springs we have a process to capture crashes that were filmed with our traffic cameras from Waze alerts. This preserves the footage from regular deletion practices and facilitates:

• open records requests
• police investigations
• intersection safety analysis

Process work flow

1. A crash occurs and is reported in the Waze feed
2. The crash location is compared to a predetermined viewshed polygon of interest. In this case we have generated viewsheds for traffic cameras
3. If the reported crash is within the viewshed, flag the alert
4. Send an email notification of this alert to recipients

This is only one example of using geofences and firing alerts. This process is highly adaptable to other use cases

Some examples from the wiki.

Traffic Study Replacement

Instead of paying $50K for a multi-week traffic study to see if your road configuration changes had an impact, instead you can use this Waze cloud database for free for instant, unlimited results. We are working on integrating our Power BI template which can replace traffic studies into this project.

Hot Spot Analysis

Find the top intersections and corridors across your entire city that have the worst traffic jams and issues so you can prioritize your traffic configuration work and have the greatest impact with the least resources.

Collision Prediction

Waze data can be used as a proxy for traffic volume, and when combined with other open data sets, can be used to do a city-wide collision prediction model.

See this example from University of Pennsylvania's Masters in Urban Spacial Analytics program for details, code, and a map. Blog post. We are working with Data for Democracy to get a similar model plugged into this project.

Faulty Equipment

Based on looking at patterns in the data on maps, traffic engineers can discover faulty non-connected traffic equipment (eg, inductive loops that sense when a vehicle is at a light) and send engineers to fix the issue.

Post Event Analysis

After a major city event, engineers can use the Waze data to see how successful they were at closing roads and routing traffic, to improve their plans for the future. See an animated map of Louisville's Thunder Fireworks show for the Kentucky Derby, part of the analysis.

Leadership Support and Funding

Prove that you have made improvements to road conditions with your mobility work, and show those results to leaders. You can use this data to make the case for future funding for new improvements.
