That is to say, one meter of cycling on separated bike path is equivalent to <em>x</em> meters of cycling in mixed traffic (reference). This paper presents an effort to estimate a bicycle route choice model in Greater Gothenburg area where the utility is specified in the Value-of-Time space (VoT), which assumes that cyclists primarily aim to minimize travel time rather than distance per se. Estimation in VoT space also allows for the use of model estimation results in Cost-benefit analysis (CBA) given that most benefits in CBA are measured in terms of travel time savings. To achieve this, travel time, desired speed and delays at intersections are estimated from GPS data. A Path-size Logit model is developed where a utility function for each alternative (route) is formulated using travel time rather than distance. Desired speed and delay at intersections are estimated at trip level and intersection level. The estimated preference weights in the VoT space are compared with the estimates in the VoD space using the same data and from the literature. Results suggest that valuation of separated bike path in VoT space is comparable to VoD space using the same dataset but lower than the ones in VoD space in literature. The valuation of very steep slope (&gt;5 %) in VoT space is substantially lower. Commuting cyclists slightly more prefer separated bike path and have a substantially stronger preference for avoiding signalized intersections than non-commuting trips.</div></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"4 ","pages":"Article 100064"},"PeriodicalIF":0.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a lack of comparative studies investigating factors influencing the travel behavior of shared micromobility in Europe. From this, we investigate shared bicycle, e-scooter, and e-moped usage in Berlin based on trip data from September 2019 to March 2022. We incorporate a comprehensive set of spatial, temporal, weather-, fleet size-, and COVID-19-lockdown-related factors. To account for significant over-dispersion in our hourly resolved panel dataset for 542 traffic analysis zones, we employ a functional spatiotemporal regression model to estimate variables of trip counts for the three micromobility modes. Our descriptive results reveal spatiotemporal characteristics of shared bicycle, e-scooter, and e-moped usage and significant growth of operating fleet sizes in Berlin in recent years. We provide evidence that fleet expansion does not lead to a proportional increase in trips, implying competitive effects among operators limit potential growth. As urban space is scarce and regulations on fleet sizes are lacking, urban planners and service providers use these findings and complementary studies to plan fleets and their allocation optimally. Impacts associated with land use vary between modes and allow for demand-based planning. Precipitation is the most impactful factor among the weather variables and shows a pronounced adverse effect on all three modes. COVID-19-lockdown phases had no significant effect on e-mopeds. While bicycles were moderately affected, e-scooter trips decreased significantly.

However, integrating e-scooters into urban environments has been challenging due to safety concerns and friction with other transport modes, leading to public opposition and potential bans. These challenges underscore the benefits of deploying e-scooters in controlled environments like university campuses, where their impact can be better managed. This study examines e-scooter implementation on a Greek campus, focusing on identifying hidden factors influencing usage levels through exploratory factor analysis (EFA). In addition, cluster analyses reveal different personality types that significantly affect usage levels. The Real-life Experiment was conducted in two phases, compared behaviors over time, and accounted for weather variations. The study innovatively integrates questionnaire and usage data to identify hidden factors affecting usage and segment users into personas. The analysis created four perception-based personas (Reluctant, Cautious, Practical, Interested but Unconvinced) and four trip-based personas (Young and Infrequent, Young and Frequent, Older and Infrequent, Older and Frequent). Chi-square analysis and Sankey diagrams visualized personas’ patterns, while ridgeline plots showed variable distributions across the two phases. Results highlighted the significant impact of safety concerns, transport challenges, perceived e-scooter benefits, and weather on utilization levels. The insights from this study provide valuable guidance for effectively implementing e-scooter systems to enhance sustainability and reduce unnecessary car trips.

The discrepancy between the use of formal and informal parking spaces may be attributed to a lack of information provided to cyclists about the available formal parking options. This study investigated the effectiveness of different traffic sign designs in encouraging the use of formal parking spaces. The designs were developed within this research with the intention of capturing different communication strategies, namely hazardous, neutral educative and negative educative. A stated preference choice experiment was then performed to allow the comparison of the effectiveness of the different designs, and thus communication strategies.

Yet, there is not much evidence from large scale surveys to substantiate this claim. Nearly 14,000 micromobility injuries leading to emergency care in the United States in 2021 and 2022 are analyzed in this study. The following questions are addressed: What are the characteristics of injured micromobility users? Are injured e-scooter users more likely to suffer severe or fatal injuries than other injured micromobility users? What is the relationship between motor-vehicles and micromobility-related injuries? Around 15 % of injured micromobility users presenting to an emergency department were admitted to the hospital. Injured e-scooter users were not more likely to suffer severe injuries than bicyclists and e-bike users. Factors influencing micromobility injury severity included: older age, being male, involvement of a motor-vehicle, and alcohol/substance use. E-bike injuries were more likely to (33 %) involve a motor-vehicle than bicycle (26 %) and e-scooter injuries (23 %). Injured e-scooter users were more diverse (e.g., a higher proportion of women and minorities) and tended to be younger than bicyclists and e-bike users, indicating a potential wider diversity of users. As micromobility becomes a growing mode of sustainable transportation, we must ensure that conditions are safe for all users. This includes separated and protected pathways for micromobility users, traffic calming measures for motor-vehicles, adequate post-crash care for all, and policies that advocate for safe usage, instead of preventing usage, of micromobility modes.</div></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"4 ","pages":"Article 100061"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143552455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vehicle sharing systems such as one-way station-based bike sharing systems (BSSs) offer one such solution in transportation, although they pose operational challenges like vehicle imbalance. While many studies focus on optimizing rebalancing operations using trip demand forecasting, the added value of precise trip demand forecasting remains unexplored. This study assesses the added value of collecting detailed trip demand data and developing trip demand forecasting models. To achieve this, we create a simulation–optimization framework representing a city BSS in operation during the day. We use a discrete-event simulator representing the system dynamics and an enhanced mathematical model optimizing the rebalancing operations. We employ clustering in the optimization module to manage larger case studies, dividing the problem into smaller sub-problems. Our computational experiments compare two main scenarios, perfect demand forecast and unknown future demand, as well as several intermediate scenarios where partial future trip demand information is available. These scenarios allow us to determine the trade-off between lost trip demand and rebalancing operations costs, assess demand forecasting benefits, and identify the budget’s upper limit for precise trip demand forecasting. Subsequently, we conduct experiments on one synthetic (35 stations) and four real-life case studies, ranging from small systems (21 and 298 stations) to large systems (681 and 1361 stations). Results reveal that precise trip demand forecasting has varying impacts on small and large BSSs, with larger BSSs benefiting the most without significantly increasing the rebalancing operations costs. We also observe that the most significant improvements occur between 0% and 40% trip demand knowledge while beyond 60%, the increase in returns diminishes. The findings of this study offer valuable insights for operators in enhancing service levels and optimizing resource allocation.</div></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"3 ","pages":"Article 100058"},"PeriodicalIF":0.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143429540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The contradictory results of studies in different contexts make it unclear whether results in one city are transferrable to another. This study aims to explore the definitions of ‘complement’ and ‘compete’ in literature and to identify the circumstances where e-scooters complement or compete with public transport using a mixed-method literature review. We combine a systematic literature review of e-scooter papers with a scoping review of bike-share studies to see if the two modes act in a similar manner. Most researchers found that e-scooters tend to complement rail but are more likely to compete with buses. Bike-share behaves in a similar manner, but the competing effect with buses is higher with bike-share than shared e-scooters. Both shared e-scooters and bike-share have a complementary relationship with public transport for commuting and longer trips. Moreover, shared e-scooters have the potential to promote public transport when deployed thoughtfully, but further investigation is needed given the novelty of the field.

This study provides a comprehensive analysis of these barriers within the US by examining bike-sharing, shared e-scooters and programs offering both services. Data was meticulously collected from diverse sources, including official bikeshare provider websites, municipal transportation sites, program reports, local news articles, and mobile applications. This comprehensive data collection methodology provides a thorough representation of 458 shared micromobility systems, encompassing all services available since the inception of shared micromobility in the US. To elucidate the specific barriers faced by users, we employed the K-Prototype clustering methodology, an unsupervised machine learning technique capable of handling datasets with both numerical and categorical features. This approach enabled us to uncover distinct patterns and groupings among shared micromobility services based on these barriers. Our analysis identified four distinct clusters: Cluster 1 faces low technical but high financial barriers; Cluster 2 excels in financial accessibility but struggles with technical barriers; Cluster 3 experiences moderate barriers with progress in reducing financial and technical challenges but still needs improvement; and Cluster 4 encounters high barriers across financial, technical, and cultural dimensions. Additionally, an in-depth analysis of these clusters is performed, considering the percentage share of bikesharing and shared e-scooter services, city sizes, regional distribution, fleet size, launching year, deployment, and operations status. The outcomes of this analysis reveal that larger cities exhibit a higher share of 'moderate barrier' (Cluster 3) systems that are currently active in the pilot phase. In contrast, shared micromobility systems from mid-size, small mid-size, and especially small cities in the US experience 'high barrier' (Cluster 4) issues the most, often with smaller fleet sizes (less than 250). Identifying these clusters is crucial for enabling targeted interventions. Rather than applying a broad, one-size-fits-all approach, policymakers and planners can develop tailored strategies that address the unique challenges of each cluster. This targeted approach ensures that interventions are more effective and equitable, ultimately improving access to shared micromobility services for all users.</div></div>","PeriodicalId":100771,"journal":{"name":"Journal of Cycling and Micromobility Research","volume":"3 ","pages":"Article 100055"},"PeriodicalIF":0.0,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
