A note on COVID-19:
In the face of COVID-19, the way people travel has seen various changes. The pandemic will have long-term impacts on transportation choices that governmental agencies and policy makers will need to navigate carefully. Most cities have resumed micromobility services, and some launched new BikeShare programs within the past year. The following resources will continue to be helpful when considering the safety of shared bikes, e-bikes and e-scooters as a mobility option.

| Shared micromobility as a first- and last-mile transit solution? Spatiotemporal insights from a novel dataset | January, 2024 | The first- and last-mile (FM/LM) problem is a major deterrent to public transit use. With the rise of shared micromobility options such as shared e-scooters in recent years, there is a growing interest in understanding their potential to serve as a last-mile transit solution. However, empirical data regarding the integrated use of shared micromobility and public transit have been limited so far. As a result, much is unknown regarding the spatiotemporal patterns and characteristics of shared micromobility trips serving as an FM/LM connection to transit. This paper addresses these knowledge gaps by leveraging a novel dataset (i.e., the Spin post-ride survey dataset) that records thousands of transit-connecting shared e-scooter trips in Washington DC.

Exploring key spatial determinants for mobility hub placement based on micromobility ridership | Daniela Arias-Molinares, Yihan Xu, Benjamin Buttner, David Duran-Rodas | June 2023 | Over the past decade, cities have witnessed a surge in micromobility services that offer flexible mobility options for citizens on an as-needed basis, such as for covering the first/last mile connection of their trips. Although these services have known benefits, including reduced CO2 emissions and less public space required for parking, there is still insufficient understanding of their common dynamics and usage, which can support decision-making in the quest for allocating new mobility infrastructure, like mobility hubs. In this paper, we propose a methodology to identify potential mobility hub locations based on the common associated spatial factors with the ridership of different micromobility services (station-based bike-sharing, dockless moped-style scooter-sharing and scooter-sharing services) in Madrid, Spain.

Next Generation Mobility Systems (Chapter 4, Energy Efficiency - Innovations: Driving Prosperity, Slashing Emissions) |
Author(s): Susan, Shaheen; Adam, Cohen
|
November, 2020 | In recent years, mobility on demand (MOD) is gaining popularity among mobility consumers. This innovative concept is based on the principle that transportation is a commodity where modes have economic values that are distinguishable in terms of cost, journey time, wait time, number of con-nections, convenience, and other attributes. MOD enables consumers to access mobility, goods and services on demand by dispatching or using shared mobility, delivery services and public transportation solutions through an integrated and connected multi-modal network. This chapter describes the different services that have emerged in the MOD ecosystem and the core enablers of MOD, such as stakeholders, business models and technology. The chapter concludes with a discussion of how MOD and vehicle automation could impact cities and the transportation network and their energy use. Click here for a link to the paper PDF. |

Jennifer Dill, Portland State University Nathan McNeil, Portland State University | 2020 | Vehicle sharing services (bikeshare, carshare, e-scooters) offer the potential to improve mobility and accessibility for disadvantaged populations. This paper reviews research related to equity and vehicle sharing, focusing on race/ethnicity, income, gender, age, and disability. The authors found evidence of disparities in the use of shared vehicles, which is only partly explained by a lack of physical proximity. Some studies reveal additional barriers to use, particularly for bikesharing. More research on barriers is necessary, particularly for carsharing. Authors identified several programs aimed at reducing barriers, though evidence of their impact is necessary to inform practice. Click here for a link to the paper pdf. | |

Lime Debuts Sidewalk Detection as their Latest Innovation to Improve Scooters for all |
Lime 2nd Street | January 28, 2020 | In January 2020, Lime and the City of San José launched a pilot program featuring sidewalk detection technology to reduce e-scooters riding on sidewalks. Lime’s new technology collects data on speed, acceleration, the vibration of underlying surfaces detected through an AI model in order to produce 95% accuracy of sidewalk detection. If 50% or more of the ride was on the sidewalk, users receive a push notification. Next steps on improving the technology are being explored. |

PI 0246 Analyzing the Potential of Geofencing for Electric Bicycles and Scooters in Public Right of Way | CalTrans DRIS | January 17, 2020 | In an effort to analyze the potential for geofencing e-bikes and e-scooters in the public right-of-way, a survey was conducted and distributed to AASHTO and various jurisdictions about agency experience. Geofencing is a virtual geographic boundary that restricts micromobility from operating in certain areas and limits speed. Certain cities require rental companies to use geofencing as a part of their permit program. There are varying results with overall consistent capabilities depending on the ping rate, GPS accuracy, and other factors. |

Jessica Lazarus, Jean Carpentier Pourquier, Frank Feng, Henry Hammel, Susan Shaheen | April, 2020 | This research paper examines how docked bikesharing and dockless e-bikesharing models complement and compete with respect to user travel behaviors. Through a case study of San Francisco, the research reveals the complementarity of Ford GoBike docked bikesharing and JUMP dockless e-bikesharing systems. Ford GoBikes were more often used for short, flat commute trips while JUMP leaned towards longer, elevation change trips. Station density and bike rack density were significant positive factors in destination choices for each set of users. | |

Impeding Access: The Frequency and Characteristics of Improper Scooter, Bike, and Car Parking | Anne Brown, Nicholas J. Klein, Calvin Thigpen, Nicholas Williams | March, 2020 | This study simultaneously investigates the parking violations of micromobility and motor vehicles. With the proliferation of app-based ride-hailing and goods and food delivery services, curb space has become contested property for cities to re-evaluate. The findings indicate that despite the negative perception of micrombility parking habits, commercial vehicles account for a disproportionate share of parking violations. As the use of micromobility increases and cities reconsider their parking policies, it is important for cities to broaden their scope to include both micromobility and motor vehicles for a comprehensive approach to ensure public right-of-way. |
