Citizens play a core role in sustainable cities as users of the services delivered by cities and as active participants in initiatives aimed at making cities more sustainable. This paper considers the role of citizens as information providers and discusses the conditions under which citizens can participate in the development of sustainable cities. The objective of this study is to document the sustainability of an urban transit system and evaluate its compliance, with citizen participation as a major contributor. The methodology used is intensive field visits, interviews, and a mixed analysis of Sant Andreu de Palomar District in Barcelona city. The circulating vehicles are quantitatively monitored, qualitative problems are detected, and the typology of vehicles and other aspects identified and detailed in the study are indicated. All this information is contrasted with that of the technological sensors in the sectors. The results indicate that vehicles in the current pattern of urban density planned under incorrect sensor operation influence sustainable behavior through agglomerative clustering. This paper provides recommendations for future urban sustainability assessment research, including the employment of mixed-methods research, among other strategies. This article is intended to assist policymakers and traffic engineers in evaluating the sustainability of urban transportation infrastructure projects considering citizens as sensors.

City Literature

Citizen participation and sustainability are two main concepts used in the definitions in the smart city literature. Citizen participation is often used within the context of improving good governance in smart cities. Its relationship with sustainability is seldomly discussed. This study analyses the relationship between the concepts of smart city, smart sustainable city, and citizen participation, and discusses how citizen participation is shaped in smart sustainable cities. In light of this analysis, seven types of citizen participation mechanisms are studied. The findings of the study reveal that sustainability in smart cities is only considered within the framework of environmental matters, while citizen participation is only considered as a mechanism aimed at supporting good governance. The study recommends using these participation mechanisms to highlight other aspects of sustainability such as securing comprehensiveness, alleviating poverty, promoting gender equality and to focus on other aspects of citizen participation such as real participation and democratic effectiveness.

Random Failures

Many systems can be represented by networks as a set of nodes joined together by links indicating interaction. Recently studies have suggested that a lot of real networks are scale-free, such as the WWW, social networks, etc. In this paper, discoveries of scale-free characteristics are reported on the network constructed from the real urban transit system data in Beijing. It is shown that the connectivity distribution of the transit network decays as a power-law, and the exponent λ is about equal to 2.24 from the simulation graph. Based on the scale-free network topology structure of the transit network, if only transit "hub nodes" are controlled well, the transit network can resist random failures (such as traffic congestion, traffic accidents, etc.) successfully.

Metro Project

In the framework of the largest urban-transit system ever built from scratch, the Riyadh Metro Project (6 lines totaling 176 km), a comprehensive investigation was carried out for karst detection, prevention and correction. This case study of the Metro Line 3 (41.6 km) seeks to show how the multi-technique geophysical survey (seismic refraction, electrical resistivity and ground penetration radar down to 40–50 m depth) was found to be a successful tool in detecting karst features. Preventive measures included systematic probing drilling to anticipate karst cavities below foundations (653 piers) and tunnel lining evaluation using 2D finite elements. Finally, this paper provides initial guidance of the corrective techniques used for each engineering challenge, such as cavity filling with grouting, geogrid reinforcement, etc.

The Right

Big data, collected in the form of social media posts and mobile phone location tracking, have great potential to inform and manage the planning and operation of transit networks in developing countries. Data are widely available, but the challenge, as with developed countries, is figuring out how best to use it. A case study method was used to consider approaches in Nairobi, Kenya; Istanbul, Turkey; and Dhaka, Bangladesh. In Nairobi, GPS location data were collected to generate the first map of the complex Matatu transit network. In Istanbul, automated fare collection systems were processed to understand better the usage of a bus rapid transit system. In Dhaka, researchers were collecting GPS positioning data to manage the city bus networks. Residents of these developing cities were frequent users of online media, as in many cities in the developing countries. This study revealed that integration of online media with location-based data provided a big data scenario that had the potential for supporting transit operations while posing challenges to the management of data mobility. It is not realistic to apply a one-size-fits-all approach to any problem in the developing world, but together the case studies show that with the right approach, technical capacity in transitional cities has the potential to grow to support higher-level data processing and make more efficient and more sustainable policy decisions for crucial urban transit networks in developing countries.
