Trigger: development application meets agency study threshold (trips/size — check agency note). Inputs: site program, site plan w/ access, agency TIA guidelines, prior studies nearby.
- Methodology memo FIRST (scope insurance): study area/intersections, count plan, trip gen (LU codes, IC/pass-by caps), growth rate & committed devs, horizon years, analysis method (HCM/Synchro settings), LOS standards. Get written agency concurrence.
- Data: TMCs at study intersections (typical Tue–Thu, school in session), tubes for dailies; apply FDOT seasonal factor
#status/verify; photograph existing lane geometry & control. - Existing conditions: code Existing per field + timing sheets (How to Read a Signal Timing Sheet); calibrate to observed queues where required; Synchro QAQC Checklist pass.
- Trip generation table: Trip Generation - Internal Capture and Pass-By — show gross → IC → pass-by → net external, with sources per line.
- Distribution/assignment: justify % (existing patterns, model select-link, gravity logic); arrow figure; volumes balance node-to-node.
- Future No-Build = existing × growth + committed; Future Build = No-Build + project.
- Operations: LOS/delay/queue per scenario; flag 95th-percentile queues vs storage (Turn Lane and Queue Checks).
- Mitigation where standards fail: turn lanes, signal mods (warrants!), timing, access changes; re-run Build-with-Mitigation.
- Site access review: driveway spacing/corner clearance vs access class; internal queue storage at gates/drive-thrus.
- Report assembly per MOC - Report Writing; every figure = its table = its text.
- QA/QC full QAQC System pass; assumptions appendix from the project note.
- Submit → comment cycle via a comment-response matrix → resubmit; archive per Project Close-Out and Lessons.
Example application: save each accepted methodology memo — the next one starts at 70%. Practice question: agency demands a 2% growth rate but counts show decline — what goes in the memo, and who decides? QA/QC reminder: volumes balance across the network in every scenario; PM ≠ AM copy-paste.
