Analysis Process

15

  • AirSage data contains

various details, including trip purpose, time of day, and subscriber types (resident, visitor, etc.)

  • Analysis consisted of

73 possible data combinations that were each mapped / assessed.

  • Travel behaviors were

layered with transit and census data.

Sample: Applied Analysis

Boardings

‒ Ridership: > 50,000 monthly riders ‒ Primary boarding locations

  • Transit Center: 500+ daily
  • Savannah Mall & Oglethorpe

Mall: ~140 daily

Key Areas Served / Major Destinations

‒ Oglethorpe Mall area ‒ St. Joseph’s Hospital ‒ Armstrong State University ‒ Walmart on Fulton Rd. ‒ Savannah Mall

High propensity

Primary Transfers

‒ To Route 14 From: 3, 6, 25 ‒ From Route 14 To: 3, 6, 25, 27, 31 ‒ Transfer Location: Transit Center

Origins and Destinations

‒ Route activity is dominated by downtown trips.

slide-17
SLIDE 17

Sample: Recommendations

Recommendations:

Enhance frequency between Oglethorpe Mall and Downtown Transfer Center.

Phase I

‒ Split Route 14 at Oglethorpe Mall ‒ Utilize 4 peak buses on North leg of route to improve frequency to downtown. ‒ Maintain service on South leg of route using remaining 2 vehicles.

Phase II

‒ Add frequency on North leg of Abercorn using new electric buses.

Route Analysis Synopsis:

Significant demand between downtown and Oglethorpe Mall area, which is the primary

  • pportunity for trips coming from West side of town

to get to the desired mall area zone most quickly/directly.

Only approx. 20% of transit trips originating at the Downtown Station continue beyond the Oglethorpe Mall.

Roughly 60% of trips originating south of Oglethorpe Mall continue into the downtown area.

Recommendation Results:

Service Hours Increase: Maintain current service hours using existing buses.

Frequency Impacts: Extended 15 minute headways

  • n North alignment

General Findings

21

 AirSage data provided insights into areas where transit service

could be considered and service streamlining.

 AirSage data provided confirmation where routes are

underperforming due to travel behavior discrepancies when compared to service lines.

‒ i.e. ridership performance is not projected to improve with reasonable route modification.

 Data highlighted critical destinations for local travel.  Much travel occurs within the region and

jobs/shopping/services located on the outer perimeter of the study area.

 Travel patterns are primarily North and South oriented inside

the urban core.

CMP Overview

Objectives

 Develop congestion management measures.  Reduce non‐recurring congestion duration.  Evaluate travel time reliability to 95th percentile.  Consider the full range of congestion management strategies.  Acceptable Level of Service (LOS).
