With the growing importance and widely application of the sharing bike system in public transportation systems in cities, many relevant problems emerged, which brought serious influence to the sustainable development of the system. The aim of this paper is first to research the existing sustainability indicators of urban mobility system through literature reviews, next it is to redefine and select the related indicators of sharing bike system through deeply understanding the evolution of bike sharing systems in cities from a sustainable point of view. Then, indicators are selected and applied to better understand the generations of sharing bike systems after the description of the different generations of sharing bike systems. The comparison highlights which characteristics of sharing bike system should be considered to adopt to a sustainable urban development and which features of the sharing bike system could need improvement and change to cater to active demand of the city development.Keyword: sustainability, urban mobility, sharing bike system, indicators,

This paper presents a practical approach for monitoring public transportation systems' performance by focusing on customer evaluations. Within the framework of the developed method, 22 indicators are aggregated for 6 different measures, which are time, cost, accessibility and transfer, comfort, safety – security and quality of service respectively. Passenger Oriented Performance IndeX (POPIX) has been developed and applied to the Istanbul Metro, Light Rail and Tram systems. The goal of this research is to propose a new customer oriented performance index for transportation systems, enabling a reliable and objective base for monitoring system performance by setting performance goals and identifying priorities. Meanwhile, the proposed methodology also allows for the investigation of the performance changes of a particular transportation system and for performance comparison of different systems directly from the customer point of view. The data of the index is attained by the Customer Satisfaction Survey of Istanbul Public Railways' 2005, 2006 and 2007. The POPIX methodology has been defined and the corresponding POPIX scores are calculated for the systems investigated. Furthermore, the % POPIX concept has been developed for the comparison of different systems. Lastly, the shifted POPIX concept has been proposed for more reliable comparison between different years. The framework has been implemented to the public railway systems and individual index scores are calculated for each indicator, measure and overall system. The measures of cost, accessibility and transfer and comfort have lower index scores. Metro index scores are superior in comparison to the Tram and Light Rail for all the years analyzed.

The City

Beirut is a car-dependent city, with 80% of Beirut citizens using their private cars to move across the city (the rate of car ownership is higher than regional and global benchmarks: 627 cars/1000 in Beirut, 550/1000 in Dubai and 170/1000 in Singapore). This reality causes two related impacts: an increased parking demand and decreased public transportation usage. Furthermore, in order to discuss these aspects, our study addresses the following question: How can the municipality’s interventions and mobility system reforms, such as smart public transportation systems and shareable mobility, reduce parking demand? As our methodology, it consists of three sections: (1) determine Beirut's parking problems by estimating parking demand and supply; (2) assess the potential effects of Beirut municipality policies in comparison to international experiences; and (3) evaluate the potential impacts of the smart public transportation system and shareable mobility in reducing parking demand. This paper studies parking growth in developing countries, such as Lebanon, and can help planners, decision-makers, and the Beirut municipality to make more informed decisions about parking policies, and to meet growing parking demand by introducing smart interventions that have high local potentials.

Real Time Information

Urban mobility is a problem that affects all cities. Providing real time information that can assist citizens on planning their trips by choosing times and itineraries more appropriate to their needs are essential on smart cities. Our project, named UbiBus, investigates how Computational Context and Ubiquitous Computing can be applied to Intelligent Transportation Systems to aid bus passengers mobility on cities, since dynamic real-time factors can affect transportation means. This paper describes the overall ideas concerning the UbiBus Project and presents some of the applications under development with their preliminary results.

Though new technologies have been applied in all industries, electric mobility technology using eco-friendly energy is drawing a great deal of attention. This research focuses on a personal electric mobility system for urban tourism. Some tourism sites such as Gyeongju, Korea, have broad spaces for tourists to walk around, but the public transportation system has been insufficiently developed due to economic reasons. Therefore, personal mobility technology such as electric scooters can be regarded as efficient alternatives. For the operation of electric scooters, a charging infrastructure is necessary. Generally, scooters can be charged via wires, but this research suggests an advanced electric personal mobility system based on wireless electric charging technology that can accommodate user convenience. A mathematical model-based optimization was adopted to derive an efficient design for a wireless charging infrastructure while minimizing total investment costs. By considering the type of tourists and their tour features, optimal locations and lengths of the static and dynamic wireless charging infrastructure are derived. By referring to this research, urban tourism can handle transportation issues from a sustainable point of view. Moreover, urban tourism will have a better chance of attracting tourists by conserving heritage sites and by facilitating outdoor activities with electric personal mobility.

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.
