Summary: Research on the spatial mismatch hypothesis explores the impact of job decentralization on job accessibility for disadvantaged groups, proposing that promoting agglomeration economies associated with transit infrastructure can enhance job accessibility for low-wage or low-skilled workers. However, concentrating economic activities beyond a certain spatial scale may absorb jobs from neighboring areas. Therefore, policymakers and urban planners should set limits on transit-oriented developments (TODs) and redistribute the agglomeration effect through land use and transportation policies to benefit underrepresented workers.

Summary: Previous studies on transit-based healthcare accessibility have overlooked travel time uncertainty and the efforts of travellers to avoid being late. This has led to inaccurate assessments of social equity. This study uses a robust method that considers travellers' risk-management strategies to provide a more realistic view of transit-based accessibility. The results show that traditional methods overestimate accessibility and fail to capture social and racial inequities.

Summary: This study proposes a new strategic transit design methodology that prioritizes accessibility and equity. By using ethical principles, the study aims to enhance vertical equity. The difference principle is identified as the representative principle among the four ethical principles considered. The study develops a corridor transit design model that accounts for spatial supply heterogeneity. The results show that the egalitarian design improves equity, while the utilitarian design exacerbates inequity, especially when there is uneven spatial distribution of opportunities. The difference principle is useful in identifying the upper limit of equity within resource constraints or problem structures.

Summary: Cumulative accessibility measures, which quantify the number of opportunities reached within a specific travel time, are widely used but can be influenced by arbitrary choices of travel time thresholds. This paper introduces a new metric called time interval cumulative accessibility measure, which mitigates the impacts of these choices while maintaining computation and communicability advantages. A case study in Fortaleza, Brazil demonstrates that the proposed metric yields results similar to traditional threshold-based measures while making the analysis less sensitive to ad-hoc methodological choices. The new metric provides more robust accessibility estimates without compromising the communicability of results.

Summary: The COVID-19 pandemic had a significant impact on public transit in the United States, with many people changing their travel habits. However, public transit remained important for low-income and non-white households who could not drive. Transit agencies reduced services due to decreased ridership demand, increased costs, and uncertain budgets. A study found that neighborhoods with more poor and non-white households initially experienced smaller declines in ridership, but the gap narrowed as the pandemic continued. Factors such as built environment and demographics also played a role in ridership changes.

Summary: This study proposes a novel two-dimensional analysis framework to assess the spatial equity in public transit accessibility. The study incorporates door-to-door travel time and ticket price into a generalized travel cost function and measures accessibility using a log-sum formulation. It also introduces a Palma ratio of accessibility and a neighboring accessibility gap index to examine collective and individual spatial equity. The empirical case of Kunming city in China is used to analyze the distribution of accessibility and the levels of collective and individual spatial equity towards business centers, transport hubs, and 3-A hospitals. The results indicate disparities in accessibility, with utility-based accessibility to transport hubs being less than 50% of that to business centers and 32% to 3-A hospitals. The study also reveals variations in collective and individual spatial equity, with the poorest areas having significantly higher travel costs and older blocks exhibiting better collective spatial equity compared to newer blocks. Additionally, the presence of spatial inequity in public transit accessibility varies among traffic analysis zones based on walking distance and neighboring zones.

Summary: This study presents a model for lane-changing events, consisting of two interconnected phases: 'stay' and 'execution'. The model incorporates stochastic duration of the 'stay' phase based on external traffic conditions, and models the 'execution' phase using longitudinal speed profiles. Bayesian survival analysis is used to predict the probability of the stay duration before a new execution phase, addressing the censoring issue. Using real-world vehicle trajectory data, the study identifies factors influencing driver behavior in lane-keeping and lane-changing execution, such as surrounding conditions, lane-changing purpose, directions, and departure lanes. The findings highlight the impact of urgency and patience on lane-changing decisions, as well as the influence of distances and relative speeds with surrounding vehicles on acceleration behavior during the execution phase.

Summary: The steady growth of light truck use and ownership in Canada has raised concerns due to its negative externalities such as higher fatalities, increased congestion, environmental impacts, and infrastructure wear and tear. Understanding drivers' motivation for using these vehicles is crucial for policymakers aiming to reduce their usage. This study, based on data from 2,203 vehicle owners in the Montreal metropolitan area, identifies five distinct groups of drivers through factor-cluster analysis: auto-dependent families, pragmatic drivers, established drivers, physically active workers, and urban drivers. Identifying these unique groups can assist policymakers in reducing light truck ownership by influencing changes in vehicle choice, mode shifts, and land use. The findings of this study provide valuable insights for transport policymakers in comprehending the nuanced factors influencing the preference for light trucks on Montreal's roads.
