Flying Mini-Buses: Integrating Propeller-Based VTOL Microtransit into Public Transportation Networks

Abstract

The rapid urbanization of global populations has created increased pressure on existing transportation systems, often resulting in congestion, inefficiency, and a lack of accessible last-mile connectivity. This paper introduces the concept of Flying Mini-Buses—small, electric Vertical Take-Off and Landing (VTOL) vehicles designed to operate as aerial microtransit units from existing bus stations, transit hubs, and modal interchange points. Utilizing propeller-based distributed electric propulsion, these systems offer a flexible, scalable, and sustainable model for aerial urban transport. The paper explores technical design, operational frameworks, infrastructure requirements, and socio-environmental implications of deploying such systems.

1. Introduction

Conventional public transport systems, including buses, subways, and trains, provide mass mobility across urban and regional environments. However, these systems often struggle with last-mile delivery, inefficiency in dispersed geographies, and time constraints imposed by congested roads.

The emergence of Urban Air Mobility (UAM), particularly small-scale electric VTOL (eVTOL) systems, introduces an opportunity to extend the functionality of public transport via Flying Mini-Buses—compact airborne shuttles capable of vertical lift, short-distance flight, and integration with existing transit infrastructure.

2. System Overview

2.1 Vehicle Design

Flying mini-buses are designed for short-range, low-altitude travel and typically support 2–6 passengers per unit. Key specifications include:

Distributed electric propellers for lift and cruise
Battery-electric or hydrogen-electric propulsion
Cruise range: 5–50 km
Operating altitude: 150–500 meters
Speed: 100–200 km/h

2.2 Operational Model

The vehicles operate in scheduled or on-demand configurations and are stationed at:

Major bus terminals
Urban train/metro stations
Suburban park-and-fly hubs
Multimodal transit centers

3. Infrastructure Integration

3.1 Skyport Facilities

Small-scale skyports are installed on rooftops or elevated platforms connected to transit stations. These include:

Passenger boarding gates
Battery charging pads or swap bays
AI-guided docking stations

3.2 Digital Airspace Management

Flying mini-buses operate within digitally zoned aerial corridors, controlled through:

Urban Traffic Management (UTM) systems
V2I (Vehicle-to-Infrastructure) and V2V (Vehicle-to-Vehicle) communication
AI-based real-time flight rerouting

4. Applications and Use Cases

Application	Description
First/Last-Mile Connectivity	From home or work to nearest major transit hub
Suburban-Airport Transfer	Direct flights between remote residential areas and air terminals
Nighttime Public Transit	Safe, fast alternatives after bus/train services stop
Inclusive Transport	Services for elderly or mobility-limited populations
Tourist Mobility	Scenic aerial routes connecting key urban locations

5. Environmental and Social Impact

5.1 Emissions Reduction

As fully electric systems, flying mini-buses offer zero tailpipe emissions, particularly when powered by renewable sources.

5.2 Land Use Efficiency

Their vertical operation and use of rooftops avoid further encroachment on ground-level infrastructure, preserving green spaces and reducing road congestion.

5.3 Social Equity Potential

If regulated and subsidized equitably, such services could provide increased access for underserved communities, particularly in transportation deserts.

6. Limitations and Challenges

Battery capacity constraints limit payload and flight time.
Urban airspace regulation is still under development.
Weather sensitivity, including wind, fog, and storms, poses reliability risks.
Safety certification and public trust must be established before scale deployment.
Cost per passenger currently exceeds that of traditional mass transit.

7. Conclusion

Flying mini-buses represent a promising evolution of public transport, merging aerial flexibility with ground-based efficiency. By leveraging bus stations and existing transit hubs as aerial launch points, cities can improve first- and last-mile connectivity, reduce travel times, and expand access in both urban cores and peripheral regions. With advancements in propulsion, navigation, and regulatory integration, flying microtransit can serve as a vital layer in the future of multimodal urban mobility.
