6 Commits • 3 Features
Apr 1, 2026April 2026: Delivered foundational enhancements in BayAreaMetro/NetworkWrangler that broaden the planning horizon and standardize baseline data. Key features implemented include a Baseline Network Specification Script for the 2023 Baseline Network, integration of the CalTrain Portal into the 2036 project specifications, and expansions to TIP_PROJECTS for 2030–2040 planning. No major bugs were reported this month; minor maintenance ensured consistency across project specs. Business impact includes a reproducible netspec dataset for planners, extended horizon for scenario analysis, and better alignment between transit and roadway planning data. Technologies demonstrated include Python scripting for netspec generation, data-driven project dictionaries, and disciplined Git-based version control across multiple commits.
