Introducing Osmix, our new high-performance OpenStreetMap toolkit for TypeScript that can read, query, merge, and transform OSM PBFs in the browser

Try it for yourself at osmix.dev

We're sharing a new browser-first toolkit for working with #OpenStreetMap tomorrow afternoon. Even if you missed the registration for #OpenThePaths 2026, stay tuned for more details and recordings of the sessions.

Spatial patterns of access-density mismatch reveal infrastructure gaps and strategic opportunities for new housing - npj Sustainable Mobility and Transport npj Sustainable Mobility and Transport - Spatial patterns of access-density mismatch reveal infrastructure gaps and strategic opportunities for new housing

"Access-density mismatch" helps identify "where transport systems fall short of or exceed what would be expected given existing residential density"

We introduce *transportation accessibility*—long central in planning—into legal analysis of land use & transport.

Mobility-based strategies (just one more lane, bro) create sprawl, eroding proximity & overall access. We start from a goal of access and work back.

Abundance requires this shift.

Any sort of shot we have at making transportation in the US better requires a fundamental shift in how the profession works with transportation demand modeling

🚨 Transportation for the Abundant Society 🚨

New draft paper (w/ Jonathan Levine) now up.

"Abundance" needs to grapple with transportation beyond megaprojects and institutions beyond zoning. We propose anchoring planning metrics in *access*, not speed of travel. papers.ssrn.com/sol3/papers....

Conceptual Framework: What is the Relationship Between Transportation Investments and Gentrification and Displacement? Source: The authors, based on a review of the literature. Note: Transportation investment is one factor in the complex feedback loop that causes and responds to gentrification. Transportation planners and policymakers need to understand where their work fits into this system to effectively pre-empt and mitigate the negative effects of gentrification that may be associated with transportation projects.

In our research, we first set out to theorize the potential relationships between transportation & gentrification.

Transport investments could result in increased access & desirability, and this, in turn, could increase home values. This could, in theory, result in displacement of marginalized ppl.

You may have heard of Bicycle Level of Traffic Stress

Now, help researchers develop Pedestrian Level of Traffic Stress by taking this survey

Good pictures (and video) of intersections and straightforward questions, should take you 5-20 minutes depending on how thorough you are

The link between low-stress bicycle facilities and bicycle commuting - Nature Cities Bicycling offers a range of benefits for urban commuters, but the facilities that best facilitate bicycle lane use are still unclear. Using data from 28 US cities, this study found that bicycle lanes ...

Great new longitudinal research from Drs. Nick Ferenchak and Wes Marshall, showing the value of protected bike lanes (over single stripes, sharrows, or nothing) in increasing rates of cycle commuting.

Figure 9 from https://authors.elsevier.com/sd/article/S1077-291X(25)00007-4 A map of Edmonton showing the municipal boundary, on-demand zones, and accessibility change (in 10,000 jobs) based on median wait times for on-demand zones. Most of the access changes are green (30k-50k increase in access to jobs), with some areas of dark green (50k-110k increase) and yellow (0-5k decrease)

Have you ever wondered how to integrate on-demand transit options into detailed assessments of access to opportunities?

FHWA’s “Bike and Ped Planning, Program, and Project Development Guidance” is an invaluable resource IMHO.

It tells the policy “story” of exactly where/how walking and biking projects are accommodated within the laws, regs, and policies around the Federal transpo.

www.fhwa.dot.gov/environment/...

"... tracing how accessibility rose to prominence and became the guiding principle for measuring transport and land-use outcomes."

Who's got examples of transit agencies doing really good station area planning? Looking at station and entrance/egress design, multimodal integration, bike and pedestrian access, and land use.

More highways --> More driving --> More emissions

UCLA researchers: "Across the U.S., new and widened freeways accounted for 55% of the observed increase in freeway driving [from 2000 to 2019]."

Over the last year, Conveyal worked with leading-edge agencies and practitioners around the world to embed access measures in transport decision-making and policy.

We're grateful for all of our collaborators and partners who are advancing more sustainable transport. More: mailchi.mp/61a6c6070c64...

I print and sell maps, too! The "Transit Maps" collection has some stunning maps, but none more so than this astounding, almost psychedelic, isochrone map of the time taken to travel from Paris to just about everywhere else in France by rail in 1882.
