Railways are one of the most popular means of mass transportation systems. The proposed approach has a universal characteristic that can be applied by cities or authorities to design a strategic plan of urban transportation systems that can solve advanced transportation problems. This study focused on designing a new railway network between two big cities in Malaysia—Kuala Lumpur and Kuantan. The simulation model applied for planning the new railway design and analysis is an important factor. The overall objective of this approach is to increase the advantages of passenger service and public transportation systems as well as to make available other transportation means between these two cities. In addition, the model will also choose the best railway network that can accommodate more passengers along the routes between these two cities.

Background: The present situation in megacities is characterized by traffic congestion, capacity limits of public transportation systems. In addition, environmental regulations due to potential health risks will have an increasing impact on urban transportation systems. Aim: In this paper, we describe major technology trends in transportation and in information and communication systems which will influence urban transportation in future megacities. Based on these trends a vision of a sustainable urban transportation system is developed. Method: In a first step, trends in urban development and the individual needs are analyzed. Digitalization of transportation and communication technologies offer new business opportunities for Artificial Intelligence (AI) based services. Results: The intelligent combination of advanced transportation technologies in large buildings and AI based services enables a vision of Mobility on Demand, representing a flexible and sustainable urban transportation in future megacities. Conclusion: The vision Mobility on Demand illustrates the effective and flexible integration of individual transportation needs into public transportation systems. Depending on the standards of future individual vehicles such vehicles could be integrated seamlessly into the urban Maglev transportation system.

History Of

AbstractIn the summer of 1828, the Entreprise générale des Dames Blanches launched a fleet of white omnibuses onto the streets of Paris. These public transportation vehicles were named and fashioned after Boieldieu's opéra comique La dame blanche (1825): their rear doors were decorated with scenes of Scotland, their flanks painted with gesturing opera characters, and their mechanical horns trumpeted fanfares through the streets. The omnibuses offered one of the first mass transportation systems in the world and were an innovation that transformed urban circulation. During their thirty years of circulation, the omnibuses also had a profound effect on the reception history of Boieldieu's opera. When the omnibuses improved the quality of working- and middle-class life, bourgeois Parisians applauded the vehicles’ egalitarian business model, and Boieldieu's opera became unexpectedly entwined in the populist rhetoric surrounding the omnibus. Viewing opera through the lens of the Dames Blanches, Parisians conflated the sounds of opera and street, as demonstrated by Charles Valentin Alkan's piano piece Les omnibus, Op. 2 (1829), which combines operatic idioms and horn calls. Through these examples and others, this study examines the complex ways that material culture affects the dissemination and reception of a musical work.

The Impact

The transmission risk of airborne diseases in public transportation systems is a concern. This paper proposes a modified Wells-Riley model for risk analysis in public transportation systems to capture the passenger flow characteristics, including spatial and temporal patterns, in the number of boarding and alighting passengers, and in number of infectors. The model is used to assess overall risk as a function of origin–destination flows, actual operations, and factors such as mask-wearing and ventilation. The model is integrated with a microscopic simulation model of subway operations (SimMETRO). Using actual data from a subway system, a case study explores the impact of different factors on transmission risk, including mask-wearing, ventilation rates, infectiousness levels of disease, and carrier rates. In general, mask-wearing and ventilation are effective under various demand levels, infectiousness levels, and carrier rates. Mask-wearing is more effective in mitigating risks. Impacts from operations and service frequency are also evaluated, emphasizing the importance of maintaining reliable, frequent operations in lowering transmission risks. Risk spatial patterns are also explored, highlighting locations of higher risk.
