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.

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.
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.

Have you ever wondered how to integrate on-demand transit options into detailed assessments of access to opportunities? Check out this new analysis of Edmonton's combined bus network redesign and expansion of on-demand transit zones. authors.elsevier.com/sd/article/S...
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)

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/...

Detailed multimodal isochrones for the Sepulveda Transit Corridor project in LA? 👀 These ones look familiar! "The varying shades of blue reflect differences between the alternatives..." 🚇 vs. 🚝 options provide notably different levels of access.
Maps showing "where you can go in 60 minutes" from selected station locations north and south of the Sepulveda pass. Each comparison shows "no project" (without rail in the Sepulveda Transit Corridor) vs. heavy rail/monorail "project alternatives" for the corridor.
