DOING NOTHING

As required by the FTA, we always carry forward a “No-Build” or “Do Nothing” alternative for comparison. For the Orange Line Corridor, this would include making no changes to the existing service on MetroRapid Route 801.

Transitway Options

Dedicated space for transit within the right-of-way

STREET LEVEL

  • A dedicated transitway running along an existing street
  • Operations are affected by conflicts with traffic signals, pedestrians, bikes, intersections, and other street level uses

Alignment Alternatives

Alignment alternatives for the Orange Line were evaluated and eliminated during the Project Connect system planning phase. Only one alignment moved forward into the current phase of analysis. For analysis purposes, the alignment is divided into segments which share similar characteristics such as right-of-way availability and context of their built environments.

Orange Line Corridor. 1-North Austin segment from Tech Ridge to North Lamar Transit Center. 2-North Central segment from North Lamar Transit Center to Hemphill Park (29th). 3-Central Austin segment from Hemphill Park (29th) to Wooldrige Square. 4-Downtown segment from Wooldrige Square to Auditorium Shores. 5-SoCo segment from Auditorium Shores to Oltorf. 6-South Central segment from Oltorf to Stassney. 7-South Austin segment from Stassney to Slaughter.

Transit Mode

Both BRT and LRT vehicle fleets would be fully electric. Either mode would benefit from off-board fare collection, larger stations with level boarding, and intersection signal prioritization.

Bus Rapid Transit (BRT). Rubber-tire vehicles operating in a dedicated transitway. High-capacity transit vehicles powered by electric batteries. Stations with transit information, level boarding and off-board ticket payment. Signals and communication systems to keep everything running smoothly.

Light Rail Transit (LRT). Steel-wheel vehicles operating on tracks in a dedicated transitway. High-capacity transit vehicles powered by overhead electric lines. Stations with transit information, level boarding and off-board ticket payment. Signals and communication systems to keep everything running smoothly.

People on Board

Both BRT and LRT vehicles can carry large numbers of people at a time.

Bus Rapid Transit (BRT). BRT buses usually have 50-70 seats plus room for 40-50 more standing passengers. There are doors on both sides of the bus to allow people to board and exit from either side depending on where the station platform is located. About 115 people can fit on each BRT bus.Light Rail Transit (LRT). LRT train cars can usually have 60-70 seats plus room for 100-110 more standing passengers. There are doors on both sides of the train to allow people to board and exit from either side depending on where the station platform is located. About 172 people can fit on each LRT train car.

Level of Service Scenarios

High-capacity transit would help meet the mobility needs of Central Texas for many decades to come. As the region continues to grow, transit service could expand to keep up with demand. Increasing BRT and LRT service works in different ways.

Bus Rapid Transit (BRT). To carry more people on BRT, more buses are added during the busy times of the day. This means that buses are more frequent and pair up during peak hours, which requires more bus drivers. To carry 690 people per hour, one bus every 10 minutes. To carry 1,380 people per hour, one bus every 5 minutes. To carry 2,760 people per hour, one 2-bus pair every 5 minutes.Light Rail Transit (LRT). To carry more people on LRT, train cars are linked together. The length of Austin's downtown blocks can accommodate up to three train cars at a time. To carry 1,032 people per hour, one 1-car train every 10 minutes. To carry 2,064 people per hour, one 1-car train every 5 minutes. To carry 4,128 people per hour, one 2-car train every 5 minutes.

Orange Line Ridership

Ridership forecasts estimate how many customers the Orange Line would draw. Many factors influence whether or not people ride transit. Studying these factors provides an estimate of how many people would use each Build Alternative on a typical day.

DENSITY

Ridership tends to be higher in areas with more people, jobs, and activity centers.

RELIABILITY

When people can depend on fast, frequent transit service, they tend to use it more.

CONNECTIONS

More people ride transit when it makes useful connections to other transportation services.

TRAVEL TIME

Faster travel times tend to make transit a more appealing transportation option.

QUALITY

When transit has great stations and vehicles, more people choose to ride it.

COST

People tend to make choices about how to travel based on what it costs.

POTENTIAL RIDERSHIP DEMAND

Potential Ridership Demand during a typical weekday. Existing MetroRapid Route 801 has about 11,500 on a typical weekday. Metrorapid Route 801 from year 2028-2040: 10,000-20,000 riders. BRT from year 2028-2040: 35,000-65,000 riders. LRT from year 2028-2040: 40,000-75,000 riders. Note: Potential ridership demand above is presented independently from service capacity. Note: Ridership analysis was conducted using the most recent population and employment forecast available from the Capital Area Metropolitan Planning Organization (CAMPO) for 2040. This forecast was last updated in 2015 and does not reflect a number of recently completed or planned developments. Ridership estimates are subject to change based on the forthcoming 2045 population and employment forecast from CAMPO.

Travel Times

Four different types of trips showing how fast the Orange Line would travel

Orange Line Corridor indicating four different trip types. Tom's trip begins at Tech Ridges and ends at UT West Mall (24th). Ria's trip begins at Rundberg, has a stop at Koenig, and continues and ends at Republic Square. Sofia's trip begins at Slaughter and ends at Republic Square. Sanjay's trip begins at South Congress Transit Center and ends at UT West Mall (24th). Tom starts his trip at Tech Ridge and works Downtown. His current commute by car ranges from 35 to 60 minutes, while his commute by bus is 72 minutes. After, Tom's Orange Line commute would be 27-33 minutes. Ria starts her trip at Rundberg and drops off her son at daycare near Koenig before heading to work at UT. She does not own a car. Her current commute by bus is 32 minutes of traveltime but depends on how long she waits for the next bus after her daycare drop off. After, Ria's Orange Line commute would be 16-18 minutes. Sofia starts her trip at Southpark Meadows and works at the Federal Courthouse. Her current trip by car ranges from 24 to 54 minutes, while her trip by bus is 39 minutes. After, Sofia's Orange Line commute would be 15-20 minutes. Sanjay starts his trip near South Congress Transit Center and takes classes at UT. His current commute by car ranges from 22 to 45 minutes, while his commute by bus is 39 minutes. After. Sanjay's Orange Line commute would be 14-23 minutes. Note: Car travel time does not include time spent finding a parking space.

Factors that affect operating costs

BRT systems are usually less expensive to operate per bus than LRT systems are per train, but they also carry fewer people per bus than LRT can carry per train. Operating costs for LRT would also be higher initially since LRT technology would require specialized operating capabilities that are brand new to Capital Metro.

The first graphic displays the Operating Cost Breakdown. BRT and LRT showing breakdown of Vehicle Operations, Vehicle Maintenance, Non-Vehicle Maintenance, and General Administration. The second graphic states: BRT Orange Line Alternatives estimated operating cost 23 Million to 32 Million. The third graphic states: LRT Orange Line Alternatives estimated operating cost 45 Million to 57 Million. Footnote:  All costs shown in 2028 (opening year) dollars. Operating costs presented above are based on the high-end cost estimates for all alignment alternatives and include an additional +/-5% uncertainty factor. Build examples do not include offset costs resulting from bus service adjustments or impacts on fare revenues. All cost estimates are subject to change as engineering and design advances.

What Comes Next?

As we conclude the Step 2 analysis, we will incorporate your feedback, refine the alternatives and generate additional data to help us identify an alternative that best meets the project’s Purpose & Need. Capital Metro will release a preliminary recommendation for a Locally Preferred Alternative (LPA) in 2020, based on the feedback received from agency partners and the community.

The LPA Evaluation will consider criteria that the Federal Transit Administration (FTA) uses to score the project for its competitiveness for receiving Capital Investment Grant (CIG) program funding.
