Reviving the lost spaces under urban highways and bridges: an empirical study
2019
Purpose The fast development of urban movement infrastructures has created neglected urban places in cities. This study aims to provide users’ preferences for designing lost spaces that are a by-product of elevated urban highways (UHs) and bridges to develop a conceptual model for better environmental design. Design/methodology/approach This research is conducted by a combination of both qualitative and quantitative methods. In the first phase, to explore the citizen’s environmental preferences based on the Q-sort technique and in-depth interviews, the ideas of 50 users were considered up to data saturation. The preferences of people for designs under urban bridges were extracted by conten…
Automated highway systems and hard-shoulders running: A case study
2016
The purpose of this research was to evaluate the increase of capacity of existing motorway resulting from the implementation of relatively new traffic control strategies, as the automated highway systems (AHS) and the hard-shoulder running (HSR). Was examined the Italian motorway A22, belonging to Trans-European Road Network, corridor Helsinki - La Valletta. Many traffic surveys were done (year 2014) in several road sections. For each of them have been carried out the flow diagrams, the traffic flow parameters (capacity C, free flow speed vf,jam density kjam) and the relationship between flow rate of lane (right lane Qright and passing lane Qpass) and total flow rate Qt. The current carriag…
Comment Hollywood figure l’intériorité dans les films « hollywoodiens » de David Lynch, Lost Highway (1997), Mulholland Dr. (2001) et Inland Empire (…
2011
The article takes Zachary Baqué's study of Los Angeles in the films of David Lynch as a starting point to explore David Lynch's Hollywood movies. The author contends that the films offer more than a satirical representation of a corrupt, unhealthy system which threatens dreams and artistic creativity, or a parodic play on Hollywood genre and narrative conventions. Rather, Hollywood is a character, a presence, revealed as both horizontal and vertical, physical and abstract, evoking the city, the studio system, cinema and dreams, so that the satire, the visual motifs and clichés and the topography of Hollywood, and the references to Hollywood films, constitute a complex fabric of subjectivity…
Potentialities of a Highway Alignment Optimization Method in an I-BIM Environment
2019
The BIM (Building Information Modeling) approach potential in the civil engineering field opened novel scenarios in the design idea concept, from planning to executive and constructive phases. The related advantages are numerous and not only limited to a real-time interaction among the involved subjects, that can actually operate in an optimized 3D shared environment. Owing to the sharing information philosophy and to the features of various "smart objects" combined in the project, this innovation reduces potential errors and increases the effectiveness of the design solution in terms of both functionality and cost. Despite these advantages, the highway alignment design problem remains very…
The Death of the Subject in David Lynch's Lost Highway and Mulholland Drive
2003
International audience; Quel est le sujet de ces deux films qui ont suscité de nombreuses interrogations auprès du public lors de leur sortie, questions portant notamment sur la signification de la diégèse ? Nous avançons que ce n'est pas à ce niveau-là que l'on doit chercher le sens des films de Lynch. En fait, la mort du personnage comme sujet va de pair avec l'absence d'une histoire ; l'évolution du cinéma de Lynch montre que, si sujet il y a, c'est du côté du spectateur qui tient désormais le rôle de l'enquêteur que tenait les personnages dans les œuvres antérieures (Blue Velvet et la série Twin Peaks). Le sujet lynchien apparaît alors un véritable objet dans une composition qui se refl…
A PSO algorithm for designing 3d highway alignments adopting polynomial solutions
2017
Intelligent optimization algorithms for highway alignments have produced good results so far. However, considering the numerous constraints and factors directly implied in the infrastructure design, the researchers' efforts usually focus only on simplifying the alignment choice, supporting engineers in the design phase. Implementing strategic considerations regarding comfort and safety would be also very important. In this paper, the authors propose a method for designing improved 3D highway alignments using a specific optimization algorithm, based on a Swarm Intelligence technique, adopting an innovative polynomial transition curve as the unique horizontal curvature element, called PPC (Po…
Autopia revisited
2013
Contro modello sin dalla loro prima apparizione, superstrade e circonvallazioni, attraversando il tessuto come barriere o trincee, hanno accresciuto in modo determinante il numero di figure urbane della discontinuità prodotto nel secolo XX dalla relazione di infrastrutture e città. Oggi, in relazione ai nuovi scenari della sostenibilità e della decrescita, si moltiplicano i processi di rigenerazione urbana che vedono queste infrastrutture come nuove, straordinarie risorse. Negli anni ’70, la trasformazione dell’Harbor Drive Freeway di Portland in un waterfront park di 1500 ettari fu un progetto pioniere, comparabile per dimensioni a quello dell’interramento del Big Dig – la Central Artery -…
La revoca e la decadenza delle concessioni autostradali
2020
L’art. 35, D.L. 30 dicembre 2019, n. 162, prevede una serie di novità in materia di concessioni autostradali. In particolare, si stabilisce che, in caso di revoca, decadenza o risoluzione delle concessioni autostradali esistenti, l’ANAS subentri ai precedenti concessionari, per il tempo strettamente necessario a espletare le procedure di gara funzionali all’individuazione di un nuovo concessionario. Inoltre, si dispone che, ai fini della determinazione dell’indennizzo, siano da considerarsi nulle le clausole convenzionali difformi rispetto alle norme del codice dei contratti pubblici e che l’efficacia del provvedimento di revoca, risoluzioneo decadenzanonsia sottoposto alla condizione del p…
