computerized Parking facility management system
2000Co-Authors: Brett O HallAbstract:The computerized Parking facility management system (10) provides management for Parking Garages, Parking lots, street Parking, as well as no charge-for-Parking operations. As each vehicle enters the Parking facility (70) photographs of the vehicle and its license plate uniquely identify it. Additional identities include characterizing the vehicle's contour to determine its Parking location. An alternate embodiment implements the Global Positioning System (GPS) to determine Parking location. Variable message displays provide ongoing information to motorists of available Parking spaces. The system is able to identify the specific vehicle parked in any Parking spaces. The system also allows computer searching of the vehicles within the Parking facility according to various search criteria. The system can provide automatic notification of a vehicle's presence or absence based on Parking occupancy or time. A vehicle theft deterrent system can provide protection to any vehicle parked within the facility.

AVALIAÇÃO DAS CONDIÇÕES DE CONSERVAÇÃO DE PAVIMENTOS DA INFRAESTRUTURA CICLOVIÁRIA DE JOÃO PESSOA
'Portal de Periodicos UFPB', 2019Co-Authors: Oliveira, Lucas Quintino LiraAbstract:The users use urban roads to carry out their daily commutes. The infrastructure offered influences the quality of these trips, as it guarantees comfort, speed, safety and economy. Incentives for alternative means of displacement emerge as one perceives a disadvantage by prioritizing individual motorized transport. With this in mind, cycling becomes a viable alternative. Therefore, this work has the objective of evaluating the conditions of conservation of cycle pavements of João Pessoa-PB. The distress (defects) of three stretches of cycle tracks from the Southern Zone of the city were surveyed, six pavement condition indexes were applied and the results analyzed. The indexes applied were: Pavement Condition Index (PCI); Index of Urban Pavement Condition of the Federal District of Brazil (ICPU); Distress Manifestation Index Network Level (DMINL); Urban Pavement Condition Index (UPCI); Index of Condition of Urban Pavements of João Pessoa (ICPUJP); and Overall Severity Index (IGG). The indexes that presented satisfactory results were PCI and ICPUJP, because their methods cover more defects relevant to cycle pavements. Both classified the samples as Good condition. At the end of the study, it was noticed that the points of the cycle ranges that presented a greater severity or quantity of defects were located near to bus stops, accesses (Garages, Parking lots and crossings), or vehicle traffic occurred on a regular or irregular basis. This shows that these critical points, in addition to generating conflicts between cyclists and vehicles, are also aggravating to the state of conservation of the pavement, due to the speed changes and maneuvers of motor vehicles, which are responsible for the greater demands on the pavements. In addition, weathering and the quality of the drainage devices are also factors that influence the deterioration of the pavement.O usuários utilizam as vias urbanas para realização de seus deslocamentos diários. A infraestrutura oferecida influencia a qualidade dessas viagens, pois garante conforto, rapidez, segurança e economia. Surgem incentivos a meios alternativos de deslocamento à medida que percebe-se uma desvantagem ao priorizar o transporte motorizado individual. Com isso em mente, o uso da bicicleta se torna uma alternativa viável. Portanto, este trabalho tem o objetivo de avaliar as condições de conservação de pavimentos cicloviários de João Pessoa-PB. Foram levantados os defeitos de três trechos de ciclofaixas da Zona Sul da cidade, aplicou-se seis índices de condição de pavimentos e analisou-se os resultados. Os índices aplicados foram: Pavement Condition Index (PCI); Índice de Condição de Pavimento Urbano do Distrito Federal (ICPU); Distress Manifestation Index Network Level (DMINL); Urban Pavement Condition Index (UPCI); Índice de Condição de Pavimentos Urbanos de João Pessoa (ICPUJP); e Índice de Gravidade Gloval (IGG). Os índices que apresentaram resultados satisfatórios foram o PCI e ICPUJP, pois seus métodos abrangem mais defeitos relevantes aos pavimentos cicloviários. Ambos classificaram as amostras no estado Bom. Ao fim do estudo, percebeu-se que os pontos das ciclofaixas que apresentaram uma maior severidade ou quantidade de defeitos estavam localizados próximos a paradas de ônibus, acessos (garagens, estacionamentos e cruzamentos), ou ocorria o tráfego de veículos de forma regular ou irregular. Isso mostra que esses pontos críticos, além de gerarem conflitos entre ciclistas e veículos, também são agravantes para o estado de conservação do pavimento, devido às mudanças de velocidade e manobras dos veículos motorizados, os quais são responsáveis pelas maiores solicitações nos pavimentos. Além disso, intemperismo e qualidade dos dispositivos de drenagem também são fatores que influenciam a deterioração do pavimento

Residentsand#39; Elements of Legibility of Informal Settlements The case of Mlalakuwa informal settlement in Dar es salaam - Tanzania
2018Co-Authors: Justine Teyanga, Liberatus Kileki MremaAbstract:This study aims at investigating the way residents perceive their built environment in the informal settlements which are assumed to be the best field of knowledge as they are least affected by formalistic rules of the built form transformation game. The purpose of this paper is to identify residents#39 innate experiences of their built form. The researchers#39 experience on informal settlements and a transect walk conducted during the field studies at Mlalakuwa has made it possible for the researcher to clearly verify and reflect upon the applicability and universality of Lynch#39s (1960) perceptual theory on the quotImage of the Cityquot. The study realized the residents#39 understanding of the built environment through Lynch#39s five elements of legibility namely nodes, paths, edges, landmarks and districts which were encapsulated through a research based on the Eurocentric and Western Countries ideology. Data for this study were collected through qualitative research method, which involved the use of multiple tools which included in-depth interviews, observations, photographing, recording and sketching of the existing situation. Interviews and discussions with professionals, developers, residents, and non-residents were effectively conducted and narratives were produced. Moreover, archival outsourcing aiming at tracing the processes of transformation and review of literature create a body of knowledge which gravitate the context of informal settlements. The study sought to explore and document the five elements of legibility in informal settlements particularly in Mlalakuwa. Varying types of elements of legibility of the built form, their emergence and their roles were identified and analyzed. Urban nodes include bars, social halls, social clubs, religious buildings, gasoline filling stations, banks, Garages, Parking areas and education buildings. Landmarks include communication towers, electric transformers, high rise office buildings, and trees. Urban edges include roads, rivers, and bridges. Path include setbacks of buildings within the private properties. Districts are not apparent. Residents use references which are not seen from far to direct movement in the landscape. Those include famous people#39s residences, old buildings, milling factories, road type (tarmac road), religious buildings, bus stops, taxis/motorcycles/bajaj stands and bajaj stations. This paper urges urban designers, urban architects and urban planners to understand informal and formal settlements through the native elements of readability when they are carrying out design and supervision of informal settlements upgrading and regularization, and restoration and revitalization of cities. However, native elements of legibility are congruent to Lynchrsquos four elements namely node, landmark, edge, and path. Districts are not apparent due to cacophonic space sizes, development densities, and lack of technological consistency.

Sport Utility Vehicles and the Design of Parking Garages
Concrete international, 2002Co-Authors: Javed B. MalikAbstract:Sport utility vehicles (SUVs) and vans have become increasingly popular as passenger vehicles. This shift has generated wheel loads in excess of current design requirements for Parking Garages. Parking Garages for passenger vehicles are currently designed for a uniform live load of 50 lb per sq ft or a concentrated wheel load of 2000 lb spread over a 20 sq in area, but some of the larger SUVs exert a concentrated wheel load of 3500 lb or more. Wheel loads, rather than uniform loads, typically govern the design of one-way slabs and beams supporting small slab areas. This warrants a review of existing floor designs and the consideration of the use of a heavier wheel load for all new designs. This paper recommends an increase in the minimum design wheel load to 2000 lb, the use of a minimum slab thickness of 4 in, the stiffening of floors if current design is inadequate, the design of floor beams to support smaller tributary areas for actual wheel loads, and the use of a minimum unreduced live load of 50 lb per sq ft for the design of garage floors.
