Epic Information - HQTA Methodology Revisions

Summary

• We're having ongoing conversations with HCD and other State agencies and MPOs about HQTA/major transit stop methodology. The goal is to reach a consensus interpretation of the statutes, and align our dataset as closely to that interpretation as possible.
• Additionally, PRC 21155 and 21064.3 have further diverged with the passing of AB2553, we will likely have to adjust our pipeline to treat each somewhat separately.
• I (Eric) continue to prefer our segment/stop-based calculation for hq corridors interpreting PRC21155 "a corridor with fixed route bus service with service intervals no longer than 15 minutes".
• However, PRC21064.3 does specifically include the word "route", so a single-route constraint may be appropriate for intersection-based major transit stops

Will do

• implement a 20-minute standard for bus intersection major transit stops
• revise bus intersection major transit stop buffer to 500ft
• maintain 15-minute standard for hq bus corridors
• move to fixed AM and PM peak periods (6a-9a, 3p-7p), averaging frequencies within each period

Should probably do

May consider

• only counting frequencies from a single route+direction to meet major transit stop threshold (more likely)
• only counting frequencies from a single route+direction to calculate hq corridors (less likely)

Notes, misc:

• Most MPOs use 6-9am and 3-7pm as peak periods.
• 500ft is from Metro Transfers Design Guide p7, used by SCAG and agreed on in stakeholder group meeting

AB2553(passed):

SEC. 2. Section 21064.3 of the Public Resources Code is amended to read:
21064.3. “Major transit stop” means a site containing any of the following:
(a) An existing rail or bus rapid transit station.
(b) A ferry terminal served by either a bus or rail transit service.
(c) The intersection of two or more major bus routes with a frequency of service interval of 15 20 minutes or less during the morning and afternoon peak commute periods.

Deliverables

• Notebooks, dashboards, narratives, presentation details.

[edasmalchi]

intermediate column changes (roughly)

• am col (now a 3hr average) 6-9am
• pm col (now a 3hr average) 3-7pm

use additional rows (stop/route combos) to enable a shared intermediate for both definitions

[edasmalchi]

Eric to give this a first pass!

[edasmalchi]

We should also rename the dataset to make clear it includes major stops
