2021 Transit Development Plan Update - May 2021 Presented to Greenville Transit Authority Prepared by Connetics Transportation Group - Greenville, SC
Executive Summary
The dawn of the 2020s is an exciting time for the Greenville metropolitan area. The region continues to expand,
with robust population and employment growth. Between 2010 and 2019 the county population grew by 16%,
adding to 72,000 residents. Residential, commercial, and office development is abundant, and Greenville has
densified as more residents move to the county. This growth is putting pressure on the region to provide more
urban amenities and services, including Greenlink transit service.

A Necessary Update
As development changes where people live and work in Greenville County, and how they commute between the
two, it is necessary to review previous assumptions and ensure future plans match the evolving landscape. This
document is an update to the 2020-24 Transit Development Plan, which was adopted by the Greenville Transit
Authority Board of Directors in April 2018. Since the previous plan was completed only three years ago, it is
generally agreed that the previous analysis, findings, and decisions are still appropriate. Thus, this document
focuses on the changes to travel markets and developments that have occurred in the intervening three years,
and updates transit service recommendations to best serve Greenville residents.

The TDP Update focuses on three specific analyses:

    •   A review and update to the fixed route service expansion plan;
    •   An analysis of future capital costs, including new maintenance facility, additional bus stop locations,
        and accompanying vehicle plan for the proposed service expansion plan; and
    •   A plan for countywide demand response service to provide transit service to residents of the outer parts
        of Greenville County who do not have access to fixed route bus service.

The Next Ten Years
A significant expansion of Greenlink services is planned over the next ten years to meet the transportation needs
of Greenville County residents.

Projected Operating Budget Needs
The Greenlink annual operating budget for 2021 is projected at $7.03 million (FY20$), including both fixed route
and GAP paratransit service, but not including the downtown trolley. If all proposed operating plans are realized,
Greenlink would need an additional $16.07 million in annual funds (FY20$) to operate the expanded system.

The full expansion plan includes:

    •   $8.54 million in cost to increase service to the core Greenlink network, including:
            o Increases in Weekday 30-minute peak frequency on core routes
            o Increases in Saturday 30-minute frequency on core routes
            o New Sunday service
    •   $6.79 million in cost for route expansion, including:
            o 15 new routes
            o Adjustments to two existing Greenlink routes (504 and 506)
    •   $0.74 million in additional GAP service, including:

2021 Transit Development Plan Update - May 2021 Presented to Greenville Transit Authority Prepared by Connetics Transportation Group - Greenville, SC
o   Additional Saturday and Sunday service to match service expansion in the core network
             o   Additional geographic coverage to match fixed route expansion

Figure 1 provides the growth in annual operating cost by time period, while Table 1 provides a more detailed
look at operating cost of individual projects.

Projected Capital Budget Needs
A robust capital plan accompanies Greenlink’s proposed service expansion, including new stop infrastructure,
new bus vehicles, and a new maintenance facility. If all proposed capital plans are realized, Greenlink would
need between $55.68 million and $95.33 million (FY20$) in capital dollars to realize the expanded system.
However, the implementation timeline for these projects stretches past 2029, so the year over year impact of
this proposed capital budget is uncertain.

The capital expansion plan includes:

    •   $28.62 million (FY20$) to construct a new maintenance facility
    •   $7.13 million (FY20$) in bus stop improvements for expansion routes
    •   A range of $19.95 million to $59.60 million (FY20$) in bus vehicle capital costs, depending on the type
        of propulsion selected

Figure 2 provides the capital cost by time period, while Table 2 provides a more detailed look at capital cost of
individual projects.

Countywide Demand Response Concept
This TDP Update also explores the feasibility of operating demand response in the outer parts of Greenville
County beyond where fixed route and GAP service would operate. The analysis shows a need between $5.36
million and $7.44 million (FY20$), annually, to operate countywide demand response outside of the expanded
fixed route network. The range of cost depends on whether the concept is directly operated or purchased
transportation.

A capital cost of $1.76 million (FY20$) would also be needed to purchase 22 Ford Transit vehicles for the
countywide demand response concept.

Fixed Route Service Expansion Update
The Transit Development Plan adopted in 2018 included 19 new routes for service expansion. Many of these
routes were in the outer parts of Greenville County, although a few were slated for the Greenville urban core.

For the TDP Update all 19 routes were revisited-- some routes were eliminated, and others were realigned to
account for development patterns, discussions with elected officials, and conversations with community
stakeholders. The fixed route expansion is still recommended to begin in 2025, after additions to core service
are complete.

Table 3 shows the comparison between the 2018 plan and the TDP Update. Four routes were eliminated from
the 2018 plan while 15 patterns were kept and updated as noted in the table.

The proposed expansion package includes 17 routes, consisting of the 15 patterns mentioned above and two
additional routes: the Prisma Circulator and the East Pelham Circulator. This section describes the 17 route
patterns recommended for fixed route expansion. Table 4 includes a summary of headway, span by day of
operation, annual revenue hours, and annual operating cost.

Projected Operating Cost
Operating cost was estimated for the fixed route expansion plan. The first step was to develop operations and
maintenance (O&M) unit costs for Greenlink service. The 2019 National Transit Database cost data was used
and then inflated to 2020 dollars using a 1.3 percent inflation rate. The unit costs (in FY20$) account for distinct
parts of the Greenlink agency:

    •   $33.78 per revenue hour for vehicle operations costs
    •   $2.50 per revenue mile for vehicle maintenance costs
    •   $66,806 per peak bus for the variable administration costs, defined as the cost of running the Greenlink
        administration that can vary depending on the amount of service being operated

A fourth unit cost, for fixed administration costs, was not included since these costs would not change regardless
of the amount of service operated.

The second step was to estimate revenue hours, revenue miles, and peak buses for each expansion route. The
frequency and span mentioned previously was used for this estimate, as well as a high-level travel time estimate.
The results are shown in Table 5 by route. Note that changes to routes 504 and 506 both include savings by
discontinuing the existing route along with the cost of replacing with two new routes.

Additional GAP Service
Service expansion will also require an expansion of Greenville Area Paratransit (GAP) service to new geographic
areas. The cost of expansion was derived by using information on GAP service reported by Greenlink in the 2019
National Transit Database (the latest available). This information was used to calculate GAP productivity, that is,
the number of revenue hours of GAP service for every hour of fixed route service operated. This productivity was
then adjusted to account for geography and day of week, as shown in Table 6. A core route is one that operates
within Greenville city, where densities are higher and trips are shorter, thus requiring slightly less GAP service.
An outer route would operate in suburban and rural areas, where trips are longer and more GAP service would
be required.

The cost of GAP service is estimated at $77.98 per revenue hour (FY20$). For the 2025-29 period, seven routes
are recommended for implementation (three core and four outer routes). Thus, GAP would require 5,055 revenue
hours and an annual cost of $395,000 (FY20$) to satisfy demand in these new areas.

For the period after 2029, six routes are recommended for implementation (two core and four outer routes). GAP
would require 3,830 revenue hours at an annual cost of $299,000 (FY20$) to satisfy demand in these new
areas.

Employment Analysis
Access to jobs is a key goal of the expanded fixed route network. However, detailed jobs data can be difficult
to obtain. To that end, Greenlink engaged United Ministries (UM), a local nonprofit with the purpose of offering
“programs that serve and empower those in our community who are striving to achieve self-sufficiency” also
identifies access to jobs as a primary goal. In early 2021, UM staff collected jobs data to better connect
disadvantaged individuals with access to job opportunities. This data was pulled from ReferenceUSA, which, at
the time of writing, has the most comprehensive jobs listing available for public consumption. United Ministries
staff grouped jobs into seven simple categories based on SIC/NAICS codes and the skills required for several
different types of jobs, approaching the database as a potential source of information based off of the skillset
of the individual (including previous jobs held), but also what transferable skills would allow that individual to
transition to in the future.

Those categories are:

    1.   Operating equipment, working safely and efficiently
    2.   Building things, working outside, or using hand tools
    3.   Communicating, salesmanship, or leadership
    4.   Cooking, cleaning, or other hospitality skills
    5.   Using computers or working with office teams
    6.   Taking care of others or protecting others
    7.   Jobs requiring a college degree

The TDP Update conducted an employment analysis based off this dataset to understand how the expanded
network will help achieve Greenlink’s goal to increase access to jobs via public transit. A buffer analysis was
conducted for all stop locations of the existing and expanded network to understand how many jobs are
near the proposed fixed route expansion plan. The map analysis is shown in Figure 7.

For the existing network, approximately 45% of jobs in Greenville County are within 0.25 miles of the Greenlink
network. When expanding that buffer to 0.5 miles the existing network covers approximately 53% of jobs. By
contrast, the expanded network covers 66% of jobs within 0.25 miles, and 73% of jobs
within 0.5 miles. Thus, 20% more of employment opportunities in Greenville County is accessible to Greenlink
riders with the expanded network.

Capital Cost Update
The capital cost update consists of three components: the bus maintenance facility, bus stop infrastructure for
fixed route service expansion, and the vehicle plan for service expansion.

Bus Maintenance Facility
Greenlink is in the process of designing a new maintenance facility to replace the existing one located at 154
Augusta Street in Greenville. The new facility would be located on a vacant site at the intersection of Arcadia
Street and O Jones Street in north Greenville.

The cost of the facility is estimated to be $28.62 million dollars (FY20$). This is 6% higher than the 2017
estimate of the facility due to inflation. Additional propulsion infrastructure – a CNG pump and electric chargers
– are not included in the capital cost above.

Bus Stop Infrastructure
The fixed route expansion plan will require Greenlink to also expand bus stops into outer areas of Greenville
County. This section presents the methodology and capital cost for this expansion.

Methodology
Capital costs were calculated by first identifying stop locations. Remix route planning software aided this
process. Remix identified stop locations for all planned expansion routes, assigning stops at approximately 0.25-
mile intervals. These stops were then reviewed, adjusted, and in some cases, eliminated to avoid dangerous
intersections or places where topography or the built environment simply would not allow a stop to be placed.
The result is shown in Figure 8. A total of 611 stop locations were identified for the 17 new routes.

Greenlink 2021 Transit Development Plan Update                                                           Page 16
Figure 8. Stop Location Analysis

The 611 stops were then assigned to one of three stop types.

Type A
•   Includes a shelter, trash can, 12-ft x 6-ft concrete pad, and pole sign.
•   These stops were assigned to high traffic locations.
•   The estimated cost of an A stop is $26,000, including:
        o $13,500 for concrete pad
        o $12,450 for shelter/bench/ad sign/security lighting
        o $1,175 for trash can
        o $80 for pole sign
Type B
•   Includes a trash can, 8-ft x 5-ft concrete pad, and pole sign.
•   The estimated cost of a B stop is $6,100, including:
        o $4,850 for concrete pad
        o $1,175 for trash can
        o $80 for pole sign
Type C
•   Includes a trash can, 8-ft x 5-ft concrete pad, and pole sign.
•   Assigned to locations where additional permitting or easement will be needed.
•   The estimated cost of a C stop is $7,600, including:
        o $4,850 for concrete pad
        o $1,175 for trash can
        o $80 for pole sign
        o $1,500 for permitting

Bus Stop Capital Cost
The total estimated capital cost of bus stop infrastructure installation is $7.13 million (FY20$). Since routes are
planned for implementation from 2025 and beyond, this cost would not be incurred all at once and is essentially
pay-as-you-go for the fixed route expansion plan. The most expensive project would be the Blue
Ridge/Pleasantburg/Halton route, expected to cost $819,900. The least expensive is the GSP Connector, at
$26,000, since only one stop would need to be installed at the GSP Airport. Table 7 provides a summary of the
count and cost for this project by route.

Vehicle Plan
Service expansion will require a robust vehicle procurement plan. As noted above, Greenlink is currently debating
whether to use compressed natural gas (CNG) or electric propulsion for 40-ft vehicles procured for service
expansion. Both propulsion systems are addressed in the vehicle procurement plan.

The following vehicle costs were used in this estimate:

    •   18-ft cutaway vehicles: $100,000 per vehicle
    •   CNG 35-ft bus: $550,000 per vehicle
    •   Electric 35-ft bus: $950,000 per vehicle (includes electric charger installed in maintenance facility)

Between 2021 and 2024 proposed service expansion includes operation of 30-minute headways on the core
Greenlink network. Greenlink is planning to purchase six CNG buses and six electric buses to operate this service
expansion. This purchase is already funded.

From 2025 onward, the propulsion for 40-ft buses is unknown. If CNG propulsion is selected, then 36 additional
vehicles will be needed, including:

    •   Seven 18-ft cutaway vehicles
    •   29 35-ft CNG vehicles

Greenlink 2021 Transit Development Plan Update                                                           Page 19
If electric propulsion is selected, then charging and battery life becomes an issue. Greenlink is preparing to
charge electric vehicles overnight at its new maintenance facility. However, the on-street performance of electric
batteries gives some concern. While battery life will undoubtedly improve over the next few years, Greenlink is
conservatively assuming a ratio of 2:1 compared to CNG vehicle requirements.

If electric propulsion is selected, then approximately 63 total vehicles will be needed, including:

    •   Seven 18-ft cutaway vehicles
    •   56 35-ft electric vehicles

Due to the current 2:1 replacement ratio between electric propulsion and diesel, the capital cost of the vehicle
plan assuming electric buses ranges from $19.95 million to $59.60 million (FY20$). Table 8 provides a more
detailed look at operating cost of individual projects.

Countywide Demand Response Plan
This section presents the feasibility of operating demand response service for the parts of Greenville County
where fixed route service does not currently operate and is not proposed to operate as part of the fixed route
expansion plan. This analysis identified and reviewed peer agency demand response operations, developed
operation characteristics for a demand response concept in Greenville County, and estimated potential ridership
and operating costs.

Peer Analysis
A peer analysis was conducted using National Transit Database (NTD) 1 information for agencies operating
demand response service in similar locations to Greenville County. A total of 15 peer agencies were identified,
each operating demand response service in South Carolina, North Carolina, or northern Georgia. Each of the 15
operators was further investigated, and the list was narrowed to five preferred agencies that specifically provide
county-wide demand response service.

Table 10 presents the operational data for the five peers, along with a comparison to Greenlink GAP service. The
analysis review offers valuable insight into the applicability, operational metrics, and costs of county-wide
demand response services. The peer counties are similar in land area to Greenville County, but total population
varies. Greenville County has approximately twice the population of its peers; however, if the existing GAP service
area is excluded (as future demand response service would be provided for those outside of the current
Greenlink service area), then the balance of Greenville County is 189,426. This is comparable to Buncombe and
Guilford operators.

The remaining peers operate in less populated areas but provide adequate county-wide demand response
service for comparison. Mountain Mobility for Buncombe County likely offers the most similar operating
conditions to Greenville County. It is also the only peer agency that purchases transportation (PT), as the other
peers directly operate (DO) their demand response service. The peer averages for peak vehicles (21) and daily
passenger trips (237) are much larger than Greenlink’s GAP service, indicating that a substantial addition of
resources will be required to provide a countywide demand response service for Greenville.

Peer Performance Metrics
Review of the five preferred peers resulted in the calculation of key performance metrics, including daily trips
per capita, daily trips per revenue hour, and cost per revenue hour. These metrics provided insight into potential
demand, service productivity, and operational cost of future demand response service in Greenville County.

Daily trips per capita is a measurement of demand and can be applied to Greenville County to estimate daily
passenger trips (i.e. ridership). This analysis removed Hoke Area Transit Service from the calculation, as it
operates in more rural conditions and is considered an outlier for this metric. As a result, the daily trips per capita
assumed for Greenville County Demand Response is 0.0013 rides per resident.

Greenlink 2021 Transit Development Plan Update                                                                                                   Page 23
Daily trips per revenue hour indicate how productive the service is by estimating the number of passenger trips
provided for each hour of service operated. This measure will fluctuate based on the built environment. For
example, more urbanized areas tend to have origins and destinations closer together and can compound
multiple trips together for higher productivities. Lower density areas require longer trip distances, resulting in
lower productivities. The peer analysis indicates that daily trips per revenue hour metrics range from
approximately 1.0 to 2.4. For this analysis it was assumed service in urban areas result in 2.0 trips per revenue
hour while service in rural areas result in 1.25 trips per revenue hour.

Cost for demand response service can vary based on operating conditions and service provider. Most of the peer
agencies directly operate their demand response service. Mountain Mobility is the lone agency that purchases
service. Because Greenlink already operates GAP service, the cost of directly operated demand response was
assumed to be $77.98 per revenue hour, the same as GAP cost per revenue hour. Cost for purchased demand
response service was assumed to be $56.23 per revenue hour (i.e., Mountain Mobility’s service rate), with the
assumption that Greenlink would manage a purchased transportation contract with current staff.

Proposed Greenville County Demand Response Concept
The demand response concept was developed to serve the outer parts of Greenville County. This section
presents details on the operational elements, user experience, and expected operating and capital cost of the
service.

Zone Concept
The demand response concept would include four zones in outer Greenville County, shown in Figure 10. Door to
door travel would be allowed within the zone, but travel outside each zone would require transfer to Greenlink
fixed route service. All zones would be anchored to 1-2 specific “in-town” locations that allow for transfer to the
existing Greenlink fixed route network.

Boundaries for these zones were created based on population densities and/or geographic break points. The
elongated north-south nature of Greenville County and the existing Greenlink GAP service boundary resulting in
a general split of north and south sides using I-85 on the east and Saluda Dam Rd in the west. The zones were
further subdivided into “urban” and “rural” areas that reflect expected demand. The north and south urban zones
extend approximately two to seven miles outward from the existing Greenlink GAP service boundary with the
North Urban zone ending near Travelers Rest and the South Urban zone generally ending at I-185 and Highway
418. The remaining areas in Greenville County were classified as north and south rural zones.

Anchor points for north and south zones were selected across the entire system at designated key points (e.g.,
grocery/commercial areas or medical facilities) that offer transfer opportunities to existing Greenlink fixed route
services. These points are the only locations outside of the zone that the rider would be able to access. Identified
transfer locations include three northern points, four southern points, and two points that serve both north and
south zones. The anchor points are subject to change and can be limited based on origin location specified
through Greenlink’s potential future policies. The following figures depict an overview of the zone concepts and
provides details of each anchor point including the fixed route services they connect to.

Figure 10. Zone Concept Overview

Service Characteristics
A ride on the demand response service would require a reservation 24 hours in advance, like Greenville Area
Paratransit service. The concept was assumed to operate at an identical span of service to the proposed fixed-
route system, including 18 hours on weekdays, 18 hours on Saturdays, and 12 hours on Sundays. 2

Service Policies
General assumptions were made for the demand response concept.

Eligibility
     •    Any Greenville County resident living outside of the core service area, generally defined as 0.75 miles
          from the expanded Greenlink fixed route network.

Ride Requests
     •    Rider can make a request to use the service no later than 24 hours prior to their trip. They will provide
          details on pick up and drop off locations and may schedule a return trip request.

2Span of service provided matches the Transit Development Plan Update recommended hours of service and does not reflect existing
operations.

•    Software for ride requests to be determined, depending on whether service is directly operated or
         purchased transportation.
    •    Greenlink may allow for standing/recurring ride requests.

Trip Details
    •    Rider will be given a 30-minute time window for a pickup.
    •    Once onboard the vehicle, the driver will typically drop off passengers in the order that they were picked
         up (if trips are shared) but may deviate if on-vehicle software recommends.
    •    Rider will be dropped off at destination (in-zone) or at anchor point if transferring to the fixed route
         system.

Figure 11 provides a proposed anchor point system where riders could transfer to Greenlink fixed route services.
Greenlink would need to develop detailed written policies that outline specific eligibility, ride requirements, and
user costs prior to implementation.

Ridership Estimate
The peer analysis performance metrics developed in the previous section were utilized to estimate rider demand,
shown in Table 11. The rider estimate, combined with trips per revenue hour and service characteristics, resulted
in the fleet and revenue hour requirements.

Ridership Productivity
    •   Daily trips per capita – 0.0013
    •   Trips per revenue hour (urban) – 2.00
    •   Trips per revenue hour (rural) – 1.25

Service Spans and Days of Operation
    •   Weekday – 18 hours; 255 days annually
    •   Saturday – 18 hours; 52 days annually
    •   Sunday/Holiday – 12 hours; 58 days annually

Table 11. Zone Concept Ridership and Operating Statistics

Based on the above productivity and operating plan, a total of 484 daily trips are estimated to be served in the
four zones.

Capital Cost Estimate
This plan assumes Ford Transit vehicles would be used to operate all demand response service. At a cost of
$80,000 each, Greenlink would need $1.76 million (FY20$) in capital funding to implement the concept.

Operating Cost Estimate
As noted above, this analysis remains uncommitted to whether this concept should be directly operated or
purchased transportation. Table 12 presents costs for both direct and purchased options. Rates from the peer
analysis were used to develop these costs.

Purchased transportation, assumed to be $56.23 per revenue hour, would cost $5.36M (FY20$) annually to
operate the four zones. Directly operated, assumed at $77.98 per revenue hour, would cost $7.44M (FY20$)
annually to operate.
