How an expansion can improve your transit service.
Beyond simply transporting more passengers, expanding a service brings many additional benefits:- Improved quality of service through improved metrics like ETAs and seat availability rates. Good quality of service is an investment in long-term growth, as it keeps riders coming back to the service in turn driving efficiency
- Increased efficiency and lower cost per ride because fixed costs, marketing costs, and dispatching staff don’t need to scale proportionately and are spread out over greater ride volumes.
- Environmental and positive social impact measured by improved job access, fewer single occupancy vehicles, and reduced traffic congestion.
- Public recognition and economic opportunities from the state and federal government, which helps warrant funding. Transit authorities leading the service can gain recognition and be credited with the service’s success.
How to choose the right type of expansion.
The number of cities launching microtransit services continues to grow by the year , and the pace is unlikely to slow given the new sources of funding made available by the Infrastructure Investment and Jobs Act . But as microtransit matures as a mode, services themselves are also growing as city and transit agency leaders turn to on-demand transit to solve more and more of their transit challenges. Expanding a service can take shape in several ways:- Expanding existing zones to add new use cases — commuting to a new train station, accessing a new grocery store — and drive an increase in ridership.
Example1: Fill a transportation gap of sustainable, easy-to-use transit across Malta. Mapped in Remix.
- Adding new zones where existing transit coverage is low, or demographic information — like population density, or the rate of households living in poverty, or without a car — suggests microtransit could be a success.
Example2: Adding new service zones in Milwaukee, Wisconsin, to better fill transit gaps and connect riders to existing fixed line infrastructure. Mapped in Remix.
- Increasing vehicle hours or the size of the fleet at peak, or putting more vehicles on the road at all times, to improve quality of service and drive additional ridership.
Example 3: Analyzing the ridership trend in the original zone – planners usually consider adding vehicles or service hours if there is unfulfilled demand for seats or service hours.
- Expanding service hours earlier or later in the day to capture additional use cases, like third-shift workers or late-night leisure activities.
- Adding sub-services within the same zone, like commingling paratransit with an existing microtransit service, using shared fleets, shifts, or trips.
Example 4: Commingling shifts or trips requires a driver app that informs drivers whether an upcoming pickup is a paratransit or microtransit rider, and whether the rider has any special needs. (Product-Para-booking-1)
Using data to identify expansion opportunities.
When thinking about where and how to expand, a data-driven planning approach — incorporating multiple layers of transit- and demographic-related information — can help agencies identify the right types of expansion that best support their networks. Consider the following factors before launching expansions:
a) Demographics data for zone expansions.
Understand where high-density, underserved populations — lower-income, car-free, low English proficiency — intersect with transit deserts in order to see where the expanded public transit services will have the greatest impact on access and equity.
b) Existing transit conditions for zone expansions.
Visualize how existing fixed lines and on-demand transit serve the community and identify gaps. Prioritize expanding service to transit deserts, where demand for public transportation is high but supply is low.
c) Ridership patterns for zone expansions and hour expansions.
i) Consider where riders are going,
and where they want to go
.
When ridership growth is stagnant and survey feedback showed that riders would favor new areas — or if many app sign-ups and points of interest occur outside the service zones — transit providers may consider filling those needs.
ii) Consider when riders travel,
and if they’d prefer to travel earlier or later. If app sign-ups and sign-ins occur shortly before or after your service hours end, riders may welcome expanded service hours.
d) Quality of service for fleet and hour expansions
. Understand how current riders are experiencing the service: are they walking a long way to pickup points, or waiting a long time for rides? Agencies may consider expanding the fleet, increasing the overall vehicle hours, to improve service quality and drive additional demand.
e) Zone and geography.
Ensure that the new zone request can be fulfilled within budget, making the most use of current infrastructure resources in a cost-effective way. Consider road speeds and natural barriers, like bridges or highways, which can be used as indicators for the right zone shapes and sizes.
By leveraging these data insights, cities can clearly identify where and what to expand, and even predict community impacts led by network optimization.
