Hi everyone,
I am writing to follow up for those who were interested in responses to my
post re: VMT/Traffic Density Analysis as a proxy for health impacts of
transportation (e.g., near-source air pollution, noise, active transport
hazards, and livability generally) - see below.
They are summarized as follows. Please feel free to contact me off-list if
you are interested in PDFs of the referenced articles (the first one is
downloadable free online at the link included below the citation).
Best,
Megan
Summary:
- MPOs running a travel forecasting model would have the capacity to do
this type of analysis
- Caveats of mapping modeled VMT using an MPO’s regional model for a
small/sub-city level scale (e.g., TAZ, census block/tract, 1/2 mile grids)
shared by one MPO include:
1. The regional model doesn’t include most of the local roads
2. The regional model would need future recalibration to show
more accurate result for the sub-areas.
- The Boston Region MPO has started aggregating VMT from their travel
demand model by transportation analysis zone (TAZ) and turning it into a
contour surface for transportation health impact analyses.
This approach is described in the article I had shared in my initial email
- available online at the link below.
Characterizing urban traffic exposures using transportation planning tools:
an illustrated methodology for health researchers.

Sent by: h+t--friends-bounces(a)chrispy.net
Hi everyone,
I am writing on behalf of Rajiv Bhatia with an inquiry re: whether people
working at MPOs have quantified, modeled or mapped VMT or traffic density
at a smaller area/sub-city level.
If you have, could you please email me directly (megan.wier(a)sfdph.org) with
some details regarding this work and your data source(s)?
If you have not but have plans to do so and/or the data available to do so,
I would be most interested in hearing about it as well.
For some background regarding this approach and implications for health,
please see the attached article.
Thanks so much in advance -
Best,
Megan
