Integrating emerging mobility services into existing transportation systems presents significant challenges. This study introduces an innovative mobility service model that combines Personal Rapid Transit (PRT) technology with low-speed autonomous vehicles to enhance mobility and improve first- and last-mile connectivity through on-demand, door-to-door services. To evaluate the feasibility of this model in a developed urban environment, VISSIM simulations were conducted, focusing on reallocating time and space resources at critical signalized intersections within the studied network. The analysis explored various configurations for PRT-dedicated lanes—including mid-roadway, roadside, and one-way layouts—and tested different signal timing strategies at two intersections in Kasugai, Japan. The findings highlight an optimal integration plan that ensures efficient PRT operations while minimizing disruptions to overall traffic flow. By aligning infrastructure design and signal control with the specific requirements of emerging mobility systems, this study addresses practical implementation challenges and provides actionable insights for deploying innovative mobility services.

The aviation industry has a key role in international trade activities. Most studies measure aviation performance based on airlines or airports. However, the frontline operation is delivered via air routes and more operating characteristics can be revealed with route-based performance evaluation. Further, the traditional data envelopment analysis (DEA) approach cannot rank performance in a particular context which represents an efficiency frontier built by decision making units (DMUs). Therefore, this study uses a context-dependent DEA approach to measure and rank the performance of air routes with a case study of 112 international routes from two airlines in Taiwan. Model results identify eight performance levels with most air routes at efficiency performance level 2 and level 3 and most route destinations in East Asia (e.g., Japan). The results of this study can inform operators about a clear relationship between performance and potential markets as well as improvement strategies.

Transit-oriented development (TOD) is a major planning tool to promote green transport mode share. There are many previous studies in this field but with very diverse research focuses and outcomes. This study has classified the research purposes of previous studies into four categories: exploratory; potential and challenges; performance evaluation; and in-depth investigation. To identify critical factors that might influence green transport systems, a systematic literature review is delivered via a meta-analysis. Specifically, green transport mode share was set as the dependent variable and a proxy for TOD outcomes. From the model results, several key factors are identified. For example, built environment planning (e.g., pedestrian sidewalks) plays a critical role in green transport systems. The main findings of this paper can provide clear direction to current TOD, such as how to improve TOD outcomes and providing planning guidance for potential TOD.

In recent years, there has been an increasing demand for “Michi-no-Eki.” These roadside stations in Japan help solve food desert problems and enhance social interaction. Accordingly, the number of Michi-no-Eki with various urban amenities (e.g., supermarket, restaurant, and playground) has been increasing. However, there is no statistical model that can calculate the impact of a Michi-no-Eki with urban amenities on shopping difficulty or social interaction. Consequently, it can be difficult for local authorities to assess the need, the location, and the design of a Michi-no-Eki with urban amenities to ease shopping difficulty and enhance social interaction. This study aimed to (1) confirm the influence of Michi-no-Eki with urban amenities on shopping difficulty and social interaction, and (2) identify the factors influencing the impact of such Michi-no-Eki to support development of statistical models for shopping difficulty and social interaction.

This study develops a more stable model to simulate the global container cargo flows in the intermodal network with link capacities by improving the existing model with incremental assignment and parallel computing. The developed model is validated by comparing it with the observed port cargo throughputs and sensitivity analyses. Subsequently, the model is applied to the ASEAN region and China to examine the impact of logistics corridor development policies. Specifically, the scenarios improving borders between ASEAN and China confirm that improvements in Myanmar borders would shift cargo from other ASEAN countries, while improvements across ASEAN would increase the region-wide land transit cargo. The scenarios improving borders in the East–West Corridor (EWC) of the Greater Mekong Subregion confirm that the EWC is in competitive and complementary relationships with Thilawa port. Finally, the scenarios adding liner services suggest stimulating the demand by improving Myanmar's domestic logistics network than encouraging border crossings.

Delays of container services seriously affect the lean, extensive global supply chains such as the just-in-time system. A major cause of ship delay is port/terminal congestion, causing offshore waiting, and these delays create a domino effect on other ships through terminals and ships. During the supply chain crisis, started from the second half of 2020, many ships were forced to wait offshore for more than days at major ports, especially in North America, Europe, and China. This study developed the method for identifying offshore waiting ships of terminals, calculating the waiting time of these ships, and estimating the increment of CO2 emissions by utilizing log data sent from ships’ automatic identification systems. The calculated results of major world ports were analyzed to understand the relation between the degree of congestion and offshore waiting time capacity and the relation between the waiting time capacity and CO2 emissions.

This study identifies focal points for the successful development and operation of Port Community System (PCS). First, we conducted a literature review and present a comprehensive and systematic overview of the focal points. Second, as a case study, we analyzed the history of PCSs and their related systems in Japan, including an analysis of the systems that had been discontinued and the trend of integration. Consequently, we found some novel focal points that had been overlooked in existing research, such as the importance of avoiding the duplication of functionalities between PCSs and existing related systems and the difficulty in making users bear the cost burden of their own system's update for system linkage with a PCS before the utilization of the PCS is spread. Finally, we discuss the implications for certain focal points, such as the target PCS usage rate.
