The following article proposes a method to identify structures inside a road network with a flow-base community detection algorithm implemented on a graph representing the city road network. According to the results obtained in the cities of Mexico and Monterrey, the method effectively divides road infrastructure into several communities and preserves geographical neighboring. The frontiers of communities match administrative divisions along with other frontiers inside the city. The identification of communities could be useful to study the heterogeneity of street connectivity inside the city which could lead to improvements in urban mobility or even the application of public policies.

Abstract The application of the concept of instantaneous speed to the movement of vehicles on a city’s road network made it possible to establish average operating speeds. With the help of software based on geographic information systems, it was possible to determine the minimum travel times required by vehicles to move between two points on the network. Through the above analysis of speeds and travel times, applied to the road network of the municipality Ocaña, Colombia, it was possible to establish the time required by various types of vehicles to travel between the different points of the road network, allowing to define the level of accessibility to move between different areas of the city. The analysis required the updating, characterization, georeferencing and determination of the instantaneous speeds for each trip in the different arcs of the network and the subsequent determination of the average travel time curves in the network. The urban area of the city is covered with an average travel time of 15 minutes and the operating speeds are between 5 km/h and 31 km/h, with variations depending on the type of vehicle (bus, taxi, motorcycle).

Theoretical Foundations

This article builds on theoretical foundations from enclave urbanism, authoritarian planning and neoliberal urbanisation to explore contemporary socio-spatial transformation(s) happening in Cairo, Egypt. Relying on a nationwide road development project, inner-city neighbourhoods in Cairo are turning into urban enclaves, whereby populations are being separated by a multiplicity of transport-related infrastructure projects. As these rapid planning processes are occurring, our article aims to explain why these developments are crucial and unique in the context of the post-Arab Spring cities. We argue that the new road infrastructure is creating a spatially and socially fragmented city and transforming the urban citizenry into a controllable and navigable body. We use an inductive approach to investigate the effects of the new road infrastructure and its hegemonic outcomes on the city. On a conceptual level, we propose that the enclaving of the city is a containment method that has erupted since the mass mobilisations of the Arab Spring. In doing so, we use qualitative analysis to explain empirical evidence showing how the city is being transformed into nodes of enclaves, where communities are getting separated from one another via socio-spatial fault lines.

In order to improve the reliability of urban road network operation evaluation, the road network regional Partition methods were launched in this paper. The geographic grid was introduced first, and a 4-level road network model was defined. Then, the spatial analysis based urban road network division method was proposed by analyzing the characteristics of road network operation. This method can reflect the influence between adjacent regional units, and improve the reliability of urban road network division. Finally, this research took a certain area in Beijing as a case study, and divided the road network as several regional units. Macroscopic evaluation result shows that it is effective for scientifically describing the road network operation status.

Promotion of cycling can improve the sustainability level of a city or an urban area. This study presents a methodology that audits the bikeability level of the urban road environment across three selected routes in the city of Volos, Greece. This methodology is a useful toolkit in order to evaluate and improve the bikeability level of the urban road environment and also evaluate existing bikeways. Four suitably trained auditors rode their bikes and evaluated the bikeability level using an audit tool in order to audit specific features that influence bicycling suitability across the road segments and intersections of the selected routes. Furthermore, the auditors graded specific features of the road environment in order to set a bikeability score for each tested route. Finally, this study concludes that the bikeability level of the selected routes was moderate and certain actions are necessary in order to be improved.

Some small- and medium-sized Global South cities have unsustainable transport systems and no information to plan interventions in addition to having limited resources for data collection. This study proposes a method to understand Public Transport (PT) ridership in cities of these characteristics, based on previous studies and by analysing available indicators related to Manheim’s macro-variables, to identify their influence on the PT ridership. The method was applied in the city of Mexicali, Mexico. The results help to understand the causes of the low PT ridership and have implications for achieving sustainable urban mobility in the city. Findings reveal that mobility planning in Mexicali has been occurring without properly considering activity system related variables, so it is necessary to integrate urban and transport administration. Moreover, to increase PT demand in Mexicali, mobility strategies to discourage the use of private cars are necessary. The proposed method can be applied in other cities of the Global South with characteristics similar to the case study to understand the causes of PT ridership, so these can be considered by the agencies responsible for the planning of the city’s transportation system to promote a sustainable urban mobility.

Safety Interventions

The need for improving urban road safety, livability, and sustainability is evident. Quantitative estimates and qualitative methods/strategies can be used by road safety practitioners to design safety interventions. This study proposes a flexible integrated design framework for safety interventions on existing urban road segments and intersections that integrates quantitative and qualitative methods. The proposed design framework is divided into four stages of the safety management process: End of Network Screening, Diagnosis, Selection of Countermeasures, and Economic Assessment. Pilot applications of the proposed method were performed on existing roads of the urban road network of the Municipality of Bari, Italy. Results from the application were useful to highlight some possible problems in the different stages of the design process. In particular, the discussed problems include a lack of crash and traffic data, difficulties with defining the road functional classifications, including rural-to-urban transitions, a lack of local inspection procedures, the recurrent problems from diagnosis, difficulties regarding the safety assessment of cycling infrastructures and sight distances, the criteria for grouping countermeasures into sets, and the choice of appropriate predictive methods. In response, appropriate solutions to the highlighted problems were presented. The usefulness of the proposed method for both practitioners and researchers was shown.
