Summary: This study utilizes a multilevel network model to analyze the impact of high-speed rail on intercity technology transfer. It finds that high-speed rail facilitates intercity technology transfer and promotes innovation convergence. The centrality of cities has an effect on technology transfer, and the effect of high-speed rail is more significant in directly connected cities.

Summary: Advance seat selection fees are an important revenue source for airlines worldwide. This study examines passenger seat selection behavior and quantifies the spatial correlation structure among seats. The results show that the correlation among seats arises from similarities in both row and column dimensions, with a stronger correlation in the column dimension. Passengers exhibit non-linear price sensitivity and their willingness to pay is influenced by flight, booking, and personal characteristics. Participation in loyalty programs can also impact seat preferences.

Summary: This study proposes a machine learning model to explore the spatial impact of activity patterns on crash counts. The Latent Dirichlet Allocation (LDA) model is used to extract hidden activity patterns from vehicle trajectory data, and the Graph Convolutional Network (GCN) model builds the spatial relationship between multi-source data. Results show that daily vehicle kilometers traveled, road density, population density, commercial activity during weekends, and residential activity during morning peak hours on weekdays are factors associated with crashes.

Summary: This study explores the behavioral differences in crowding impedance and provides transport policies incorporating group segmentations. The results show that the group with a fear of disease comprises a high proportion of the elderly, while the time-sensitive group exhibits less crowding impedance on public transport. Therefore, customized transport policies should be introduced based on the requirements of each group of travelers to cope with the adverse effects of the pandemic.

Summary: This study investigates the resilience evaluation of interdependent networks. A model is developed to quantify the impacts of network interdependency on the resilience of interdependent transit networks, considering interdependency relations, network topology, flow characteristics, and demand distribution. The model is applied to the metro and bus networks of Xi'an, China. Results show that node degree heterogeneity in topology, bidirectional function dependency among networks, and flow matching between networks are important factors influencing network resilience.

Summary: This study evaluates how public bike-share networks in five U.S. cities have addressed equity issues throughout their years of service. The results show that higher-income and White populations have better access to bike-share service areas. However, as networks expand into lower-income and more racially diverse areas, some equity gaps have narrowed.

Summary: This study investigates the relationship between multimodality and perceived transport adequacy and accessibility. The results show that multimodality is burdensome, especially for car-dependent individuals, and leads to lower perceived achievement or accessibility for those with limited access to a car.

Summary: This study uses the propensity score potential outcome framework to investigate the impact of rumble strips on crashes on horizontal curves. The findings suggest that centerline rumble strips reduce sideswipe and head-on crashes but increase run off the road and hit fixed object crashes. Shoulder rumble strips, either alone or in combination with centerline rumble strips, decrease crash frequencies for most types except sideswipe and head-on crashes.

Summary: This study explores the safe spaces maintained by pedestrians and e-bicyclists when crossing streets. Using drone footage, the researchers found that e-bicyclists maintain semi-elliptical safe spaces while pedestrians maintain semi-circular safe spaces, with the sizes of these spaces increasing in proportion to relative speeds. The findings bridge an empirical gap in the existing literature and have practical implications for urban planning, traffic management, and the safety of vulnerable road users.

Summary: Vision Zero aims to eliminate deaths and serious injuries from motor vehicle crashes using a systems approach. Policy and program interventions can motivate drivers to make safe decisions and technology can address risks caused by driver impairment. The safe system within the normal driving envelope can accommodate human errors but cannot compensate for deliberate rule-breaking. The key role of behavioral programs and policies is to motivate safe decisions. There is potential for improvement in implementing programs and policies.

Summary: The axle load limit plays a crucial role in determining the costs associated with highway construction and truck transportation. This study examines the optimization of the axle load limit for rural roads, taking into account advancements in road construction technology, construction funding, and vehicle manufacturing techniques. A programming model is developed to maximize the cost gap between scenarios with and without incremental limits. The findings suggest that a limit of 13 tons maximizes the reduction in system costs, resulting in significant annual benefits.

Summary: This paper experimentally investigates the impact of routing advice on strategic uncertainty and finds that user-optimal recommendation can reduce strategic uncertainty and stabilize traffic flow, while system-optimal recommendation has the opposite effect. Participants with faster decision-making are more likely to comply with the advice and have lower travel costs.

Summary: This study investigates the changes in crowding multipliers for subway, ridehailing, and microtransit in New York City during and after the COVID-19 pandemic. The results show that post-pandemic crowding multipliers are either similar or lower than during the pandemic, depending on the transportation mode and masking compliance. Vaccination requirements did not significantly impact respondents' choices, but respondents were willing to pay to reduce their transportation mode's carbon footprint. The study suggests that commuters' aversion to crowding will gradually decrease, but it remains uncertain whether crowding multipliers will return to pre-pandemic levels or establish a new normal.

Summary: As bike-share systems spread in the US, understanding the different segments of bike-share users is crucial in expanding and benefiting more people. This study analyzes bike-share user data in Sacramento and identifies low-income individuals, zero-car households, students, and transit and car-share users as significant market segments. The results show that bike-share is widely adopted, particularly by those with limited means of transportation. Targeting low-income and zero-car owners can help increase bike-share demand and enhance social equity.

Summary: Planning road safety interventions on large road networks is a complex process that involves estimating safety performances, identifying sites for improvement, defining types of safety measures, and considering budget constraints. This study proposes an integrated multi-layer framework that addresses these issues and provides the number and type of safety interventions for a wide road network with different road elements. The methodology is applied to a case study, demonstrating its applicability and flexibility for planning purposes.
