Last week in our civil engineering forum, discussions were rich with diverse insights. Members delved into the importance of shifting focus in urban planning from vehicle counts to pedestrian traffic, highlighting a trend towards more human-centric city designs. There was also a significant interest in personal development, with professionals sharing their plans and seeking advice on upskilling for 2025. Conversations on the design rationale behind common traffic signs and strategies for coordinating project deliverables rounded out the weekβs topics.
This Weekβs Hot Topics
Counting people, not cars downtown
This discussion is rethinking urban planning by emphasizing pedestrian traffic over vehicle counts. Itβs a shift that could significantly impact how we design future cities. Read more here

Thanks for catching up with us. Weβll be here next week with more discussions and updates to keep you in the loop.
We just retimed a downtown corridor to ped-first using 15βmin rolling peak counts and a quick 2βhour manual tally; vehicle LOS slipped a notch, but conflicts dropped and crosswalk compliance improved β totally worth it, those LOS charts. If budgets are tight, pilot one intersection on a Friday PM and a Saturday midday before scaling. @Maya a short QGIS refresher plus StreetLight OβD was enough for us to sketch desire lines without commissioning a new study.
Quick example: on a stadium corridor we used two weeks of video analytics to map pedestrian desire lines and converted a slip lane to a raised crosswalk with an LPI; conflicts fell while vehicle delay stayed tolerable. If you try this, count late-night and weekend periods β nightlife shifts the peak like a food truck. On freight streets, Iβd pair ped-first timing with defined off-peak loading windows instead of all-day restrictions, @jackson4243.
On a collegeβtown main street, we did a 2βhour tally of strollers, mobility devices, and school groups and used it to daylight two corners and add a median refuge; drivers yielded more and vehicle delay barely budged β like moving the door to where people already walk. Small caveat: check fireβtruck templates and delivery windows before tightening radii; @rodriguez72, NACTOβs guide has a quick primer on daylighting/crossings: https://nacto.org/publication/urban-street-design-guide/intersection-design-elements/crosswalks/daylighting/.
We had good results switching a neighborhood commercial strip from pushbuttons to passive thermal detection that auto-calls the walk at lunch and lowering assumed walk speed to 3.0 ft/s; compliance and comfort jumped without touching striping. Just watch your transit signal priority so you donβt mess with bus headways. @MayaK, NACTOβs note on pedestrian speeds helped us justify it: Crosswalks - NACTO β it felt a bit like giving people an express lane on foot.
Weβve had luck using stop-level alighting data from the transit agency to place crossings where people spill out β on Main & 5th we slid a marked crosswalk about 30 m toward the bus stop and kept the same signal plan; near-miss reports dropped right awayβ¦ If data access is tight, a quick βrideβalong and count alightersβ with @SamirTranβs ops team got us close enough.
On a campus edge project, we put in temporary curb extensions with water-filled barriers and daylighted two corners; cost was under $6k and we installed over a weekend. Midday peds went up about 18% and yielding improved; , we did have to add a signed loading bay to stop trucks from blocking the taper. Simple rule we used: βcount people first,β and @liam_jac81βs placement comment lines up with that.
Lighting made the biggest dent for us downtown: we re-aimed and swapped in forward-throw LEDs to get about 20β30 lux vertical at the crosswalk and night yield rates rose about 18% without touching signal timing (FHWA primer: https://safety.fhwa.dot.gov/ped_bike/tools_solve/fhwasa14035/). Small caveat β keep CCT at 4000K or lower and shield to avoid glare; anyone tracked ped delay changes after lighting upgrades?
