This thesis proposes and designs an autonomous transportation robot. It can provide elders and disabled people to cross the crosswalk safely with sensor information fusion for real time decision-making and control by fuzzy inference and the information of image, radar, and encoder etc. In this study, the vision system makes feedback of position offset, and declination angle through the fuzzy controller, the robot could modify the attitude error to cross the crosswalk completely. This thesis considers obstacles in the forward path. Using the vision feedback information to design the fuzzy controller, it can supply obstacle avoidance to make the transportation smoothly. Besides, we also address the robot guide at a crosswalk interface point. The detection of special purpose road for the blinds on the vision system can guide the robot to make a right turn or left turn to the next intersection. In cooperate with the intersection-agent system for collision avoidance, the robot could pass through the next crosswalk safely in order to finish the whole safely intersection system.

With increasing energy costs as well as rampant congestion in major U.S. cities, the popularity of walk and bike mode choices have increased in recent years. Thus, the obtainment of a comprehensive knowledge of pedestrian and bicyclist behaviors is of great importance. The National Highway Traffic Safety Administration estimates that 11.1%#37; of pedestrian fatalities and 18.5%#37; of bicyclist fatalities in the U.S. occurred in Florida in 2011, which accounts for just 6.1%#37; of the nation's population. Additionally, intersections are hotspots for vehicle-pedestrian conflicts, which is confirmed by the Federal Highway Administration's estimate that nearly one in five pedestrian fatalities occur at intersections in the U.S. Since both signalized and non-signalized intersections are conflict points for vehicles, pedestrians, and bicyclists, it is essential that traffic control methods ensure that safety is not compromised. To examine the safety effects of different walk modes at signalized intersections, four locations in the Tampa Bay area were chosen. Two of the locations operate with Rest in Walk and Pedestrian Recall and the other two operate without Rest in Walk and Pedestrian Recall. A total of 26 hours of data were collected in early 2013 at the four study sites, which yielded 202 pedestrian and bicyclist observations. Upon modeling behaviors using a multinomial Logit model, the presence of Rest in Walk and Pedestrian Recall on minor street pedestrian phases, which operate concurrently with major street vehicle phases, was found to encourage higher pedestrian and bicyclist compliance rates than their absence. Additionally, the presence or absence of the combination of both Rest in Walk and Pedestrian Recall was found to be the most influential variable examined.

The dangers of using a cell phone while driving are well documented, but recently studies have aimed at determining the effect cell phones have on a pedestrians’ walking behaviors. This observational experiment captured video footage of distracted pedestrians, or pedestrians using cell phones, when using two different crosswalks (midblock and intersection) on the campus of Mississippi State University in order to study safety behaviors, such as speed, number of looks, and wait time. Two types of crosswalks were filmed until a sufficient number of pedestrians (N=982) were recorded. All variables (cell phone use, gender, type of crosswalk, presence of car, time of day, and density) significantly influenced speed and number of looks. Gender, type of crosswalk and presence of car all showed significant effects on wait time of pedestrians. Pedestrians observed using earphones were observed to look more and to walk slower than any other level of cell phone use.

It can be difficult to guide yourself across a crosswalk when your visual capabilities are limited, which can be an everyday issue for someone with impaired vision. This paper aims to alleviate that issue for zebra stripe crosswalks by proposing an algorithm that incorporates multiple properties of zebra stripe crosswalks with a neural network to assist in quickly and accurately identifying a crosswalk in video and pictures taken from a smartphone camera. This method improves the accuracy of zebra crosswalk detection in images. In a large dataset, it correctly identified 76.5% of zebra crosswalks, while reducing the false discovery rate (q-value) from 20% without using neural networks to 2.21% using this neural network method. Only 2.04% of non-crosswalk images as crosswalks using the neural network method.

Om ett företag ska utveckla en ny mobilapplikation innebär det att det måste tas fram många olika typer för att deras applikation ska kunna användas på de största mobiloperativsystem. En hybridapplikation löser detta genom att enbart utveckla de delar som måste använda enhetens hårdvarufunktioner. Detta examensarbete kommer ta upp vilka problem, och hur de löstes, som uppstod i avseende på notifikationer, cache och offlineläge i utveckling av en kommunikationsaggregator i HTML5 för Android. Det visade sig att det inte uppstod några större problem med att implementera notifikationer och cache medan offlinestödet var svårare att implementera.

<p>Predmet ove doktorske disertacije su izdvojeni pešački prelazi odnosno njihov uticaj na uslove odvijanja motornog saobraćaja na gradskim saobraćajnicama. Ocenu uslova odvijanja motornog saobraćaja na gradskim saobraćajnicama između ostalog vrši se na osnovu brzine putovanja vozila prolaznog toka na odseku koja je u obrnuto proporcionalna sa vremenom putovanja vozila na odseku gradske saobraćajnice. Povećanje vremena putovanja zavisi od veličine ostvarenih vremenskih gubitaka koji nastaju na izdvojenom pešačkom prelazu. Ključna pretpostavka na kojoj je zasnovana ova doktorska disertacija je da vremenski gubici vozačkih tokova na izdvojenom pešačkom prelazu nastaju usled pojave pešaka (ili grupa pešaka) i kao takvi utiču na smanjenje prosečne brzine putovanja tj. povećanje vremena putovanja vozila na odseku. U skladu sa tim cilj rada je definisanje modela za utvrđivanje vremenskih gubitaka vozila na izdvojenim pešačkim prelazima uz mogućnost implementacije u postojećoj metodologiji za definisanje uslova odvijanja saobraćaja na odsecima gradskih saobraćajnica. U skladu sa definisanim ciljem izvršena je analiza prethodnih relevantnih istraživanja, a zatim i prikupljane podatka o uslovima odvijanja saobraćaja u realnom saobraćajnom toku. Sistematizacijom prikupljenih podataka i primenom odgovarajućih matematičkih i statističkih alata utvrđene su zakonitosti nastanaka vremenskih gubitaka vozačkih tokova koji nastaju na izdvojenom pešačkom prelazu i formiran model za njihov proračun.</p> / <p>The theme of this doctoral thesis is the analysis of the midblock pedestrian crossings influence on traffic conditions on urban street segments. The assessment of motor traffic conditions on urban street segments was carried out on the basis of travel speed of through vehicles. Travel speed of through vehicles for the segment represents the relation between the segment length and segment running time, which implies that running time increase directly affects travel speed decrease. Segment running time greatly depends on the value of the achieved delays which occur on a midblock pedestrian crossing. The key assumption, which this doctoral thesis is based on, is that delays of vehicular flows on midblock pedestrian crossings occur as a consequence of pedestrian (or a group of pedestrians) appearance and that they affect the travel speed of through vehicles decrease, that is, the increase of segment running time. Accordingly, the purpose of this paper is defining the model for determination of vehicular delays on midblock pedestrian crossings, with the possibility of its implementation into the existing methodology for defining traffic conditions on the urban street segments. In accordance with the defined aim within the doctoral thesis, the analysis of previous relevant research studies was carried out, and then the research in a real traffic flow. The systematization of the collected data and the application of the appropriate mathematical and statistical tools enabled how to establish the rules of vehicular flows delays occurrence on midblock pedestrian crossing. On the basis of the established rules and correlation of traffic and geometric characteristics of midblock pedestrian crossings, a model for calculating the value of delays occurring in traffic flows was defined.</p>

<p>Основни предмет истраживања докторске дисертације представљала су обележја страдања пешака на пешачким прелазима регулисаним светлосном сигнализацијом са дефинисаним захтевима у погледу идентификације специфичних карактеристика страдања пешака и дефинисања модела понашања пешака на овим прелазима. У оквиру истраживања у циљу дефинисања обележја страдања пешака на територији града Новог Сада спроведена је свеобухватна анализа релевантних података. Резултати спроведеног истраживања указују да је намера пешака да чине недозвољени прелазак коловоза у већој мери одређена друштвеним утицајима (тј. субјективне, дескриптивне, нормативне и персоналне норме), него на основу личног мишљења (ставови и опажена контрола понашања). Анализа података показује да саобраћајне незгоде са пешацима као рањивим корисницима пута и њихове последице захтевају приступ који ће узети у обзир све специфичности као што су пол, старост, просторне и временске карактеристике, присуство алкохола, брзину итд.</p> / <p>Osnovni predmet istraživanja doktorske disertacije predstavljala su obeležja stradanja pešaka na pešačkim prelazima regulisanim svetlosnom signalizacijom sa definisanim zahtevima u pogledu identifikacije specifičnih karakteristika stradanja pešaka i definisanja modela ponašanja pešaka na ovim prelazima.

This proposal contains solution of the drainage, the traffic signs, the improvement of the safety and comfort of pedestrians and persons with disabilities. This redesign respects affected lands and their usage. It respects existing engineer networks and requirements of territorial plan of the town Kyjov.

The purpose of this study was to develop a test blue-print for a hospitality management capstone course to measure programmatic student learning outcomes. A total of 50 hospitality industry professionals and hospitality management faculty were interviewed through focus group discussions, and a post-focus group survey was conducted to determine a weighted percentage for each of the nine determined content domains. A test blueprint was developed from the weighted proportions determined by this study and a process by which other educational institutions could follow to establish a consistent and accurate evaluation method for a capstone course was described.

Un problema considerable en Lima es el congestionamiento vehicular, debido al crecimiento demográfico continuo, el centralismo, la escasa planificación urbanística y el crecimiento sostenido del parque automotor. La presente tesis se centra en la intersección de la carretera Panamericana Norte con la avenida Huandoy distrito de Los Olivos. La realidad problemática presente en la intersección es la gran variabilidad del flujo peatonal y vehicular bajo un sistema de semáforo de tiempo fijo. Por ende, la consecuencia de este tipo de semáforos aumenta los tiempos de cruce peatonal, es decir el tiempo que demoran los peatones en cruzar la vía y las longitudes de colas vehiculares. La investigación propone el diseño de un ciclo semafórico completamente actuado cuyo objetivo es captar la densidad de peatones en las islas de refugio y dar prioridad de paso de acuerdo con las necesidades del entorno. Para ello, se realizó un estudio de identificación de los volúmenes, tanto de peatones como de vehículos y en los que al realizar los flujogramas para un intervalo de 15 minutos se demostró la alta variabilidad de volúmenes presentes en una hora. El modelo de control de prioridad óptimo se simula y valida. Así mismo, se hace uso del módulo VisVAP del programa Vissim, para asignar la condicional de cruce. Finalmente. los resultados demuestran que, se redujo el tiempo de cruce peatonal en el sentido oeste a este en 6.38% y en 20.84% la longitud de cola vehicular. Además, se mejoró la geometría vial, esto permitió mayor área para la isla de refugio. / A major problem in Lima is vehicle congestion, due to continued population growth, centralism, poor urban planning and the growth of the automotive fleet. This thesis focuses on the intersection of the Panamerican highway with Huandoy avenue in the Los Olivos district. The problematic reality present at the intersection is the traffic light at fixed time as a traffic regulator. Owing to this, the system is inefficient for the great variability of pedestrian and vehicular volumes in the study area. And the consequence of this type directly prejudice pedestrian crossing times and vehicle queue lengths. The research proposes the design of a fully actuated signal control whose objective is to detect the density of pedestrian on the refuge islands and prioritize the passage according to needs of the environment. To do this, a study was carried out to identify the volumes, both of pedestrians and vehicles, and when performing the flow charts for a n interval of 15 minutes, the high variability of volumes present in one hour was demonstrated. The optimal priority control model is simulated and validated. Likewise, the VisVap module of the Vissim9 program is used to assign the crossing condition. Finally, the results show that the pedestrian crossing time was reduced by 6.38% and the length of vehicle queues by 20.84 %. In addition, the road geometry was improved, this allowed more area for the refuge island. / Tesis
