Big Data and Air Quality: Understanding Vehicle Emissions

This year, the Eastern Research Group (ERG), Coordinating Research Council (CRC), and StreetLight Data teamed up to validate one of the big as yet unmet promises for Big Data – the ability to better model and thus manage criteria pollutant air emissions from vehicles.

The results of our work show that using Big Data to model emissions at the county level is more accurate than industry-standard practices today. Of three different counties we analyzed, we found that:

  • Two counties would have overestimated their emissions if they used the industry-standard approach, and
  • One would have underestimated emissions by as much as 14% for a typical day and up to 110% in an individual hour.

Modeling emissions accurately matters: It allows air quality models to better predict concentrations of the regulated air pollutants ground-level ozone and particulate matter in different counties, which informs air quality planning and control strategies at the local level. In this blog post, we will walk you through the new methodology and some of our key findings.

How Big Data Builds New Forms of Civic Engagement in Your Community

In my hometown of San Francisco, California I grew up riding the municipal bus home from school with a group of classmates. As a group, we saw the San Francisco Municipal Agency (SFMTA) try a multitude of strategies to make the system more efficient and cost-effective. For example, SFMTA transformed car lanes into dedicated bus rapid transit (BRT) lanes to increase the fleet’s speed. When many of these decisions were made, most of my bus crew was under the voting age, and as teenagers, public forums were not an exciting Friday night activity.

I remember that we complained almost every day about how slow or inefficient the bus was, yet we never did anything to try to fix public transit. We never participated in the public forums or in outreach programs that gathered feedback on BRT. Now, as BRT expands, huge changes are happening to the system that affect my current commute. However, at the same time as SFMTA was inviting the public to share their feedback, I bought a smartphone. To the dismay of my parents, I used that smartphone constantly. Now imagine if my teenage obsession had allowed me to be a more active participant in decisions like the BRT, simply because SFMTA could use the location data created by my phone to develop their future plans.

Introducing StreetLight Volume: 2016 AADT Metrics

After many years of client requests, we’re releasing the first cut of our StreetLight Volume: 2016 AADT Metric on the StreetLight InSight® platform. These beta Metrics provide a very robust estimate of 2016 Annual Average Daily Traffic (AADT) for almost any road in the US.  To learn more, keep reading this blog post, or watch our recorded webinar on the new Metrics. Click here to watch the webinar. 

We believe this Metric provides estimates that are comparable or better than most of the standard AADT estimation practices for three reasons:

  • They can be obtained in just a few minutes from the cloud-based StreetLight InSight platform,
  • They are built by integrating four sources of data (including both GPS and Location-Based Services data, which is our new and better alternative to “cellular tower” data), and
  • They cost less than half as much as typical AADT data collection and estimation processes.
