- The impact of geometric and land use elements on the perceived pleasantness of urban layoutsPublication . Sousa, Nuno; Monteiro, João Pedro Medina; Jesus, Eduardo Natividade; Coutinho, JoãoThis article presents a model to estimate the impact of geometric and land use elements on citizens’ perception of urban layout pleasantness. An ordinal regression cumulative link mixed model with those elements as regressors is proposed and calibrated using data from an online survey. Results show that landscape building height and density of green areas are the factors that most impact the perception of pleasantness. Based on the model, a methodology to derive pleasantness mean scores for a city is also proposed and applied to a case study. The methodology allows for benchmarking the pleasantness of different cities or comparing neighborhoods within a city. It can be used both as an urban evaluation tool and a decision-aid for city expansion programs.
- A multicriteria methodology for maintenance planning of cycling infrastructurePublication . Pais, Filipe; Monteiro, João Pedro Medina; Sousa, Nuno; Coutinho, João; Jesus, Eduardo NatividadeThe importance of cycling as a sustainable mode has been widely recognized and, recently, its effectiveness in mitigating the spread of infectious diseases has also been under the spotlight. Fostering its use requires developing and deploying decision tools to help authorities assess the performance of their cycle infrastructure for maintenance and improvements. This article presents a multicriteria methodology based on engineering best practices and uses the ELECTRE TRI method to assign segments of the cycling network to predefined performance classes, with an aim at maintenance planning. The approach is demonstrated with a case study, which also proves scalability of the method’s data collection procedure. Case study results show that lack of safety and inadequate intersections are the main problems. These stem mostly from non-existent segregation between motorized traffic and cyclists, both along the segments and at intersections. This is typical of cities which, over the years, have prioritized motorized transportation.
