The recent availability of geo-enabled web-based tools creates new possibilities for facilitating carpool formation. Carpool Zone is a web-based carpool formation service offered by Metrolinx, the transportation planning authority for the Greater Toronto and Hamilton Area (GTHA), Canada. The carpooling literature has yet to uncover how different built environments may facilitate or act as barriers to carpool propensity. This research explores the relationship between the built environment and carpool formation. With respect to the built environment, industrial and business parks (homogeneous land-use mix) are associated with high odds of forming carpools. The results suggest that employer transport policies are also among the more salient factors influencing carpool formation and use. Importantly, the findings indicate that firms interested in promoting carpooling will require contingencies to reduce the uncertainty of ride provision that may hamper long-term carpool adoption by employees.

Ownership-based consumption mode has been perceived as the normative ideal in how consumer-brand relationships are created. Today, Access-based consumption mode allows consumers to access brands among other consumers without needing to sole- or joint own them. Even though its popularity, there is a limited and quite unclear understanding of how Access-based consumption affects the consumer-brand relationship. The purpose of this study is to investigate to what extent an Access-based consumption mode creates a consumer-brand relationship, compared to an Ownership- based consumption mode in the context of car brands. In order to fulfill our purpose, both a quantitative and qualitative research method was conducted on members of carpools representing Access-based consumption mode, and car owners representing Ownership-based consumption. A theoretical framework Brand Relationship Quality, composed of six dimensions was used to understand the consumer-brand relationship. Our research shows consistently that Access-based consumption creates a weaker relationship between consumers and car brands in all dimensions of BRQ-model compared to Ownership-based consumption. One group of dimensions identified to relate to emotional attachment; Intimacy, Brand-Self Connection and Love/Passion, have relatively higher difference between the two consumption modes. Another group of dimensions related to values of functionality and practicality; Commitment, Brand Partner Quality and Interdependence, have less difference.

Al?m de dividir os custos do percurso, o caixeiro pode se valer, tamb?m, dos descontos das high-occupancy vehicle lanes, que s?o faixas de tr?nsito que isentam ve?culos lotados do pagamento de ped?gio. A adi??o de passageiros ao PCV, um problema restrito ao roteamento, cria um vi?s colaborativo que ? intensificado pela considera??o das faixas especiais. Tal cen?rio confere ao problema estudado um aspecto ecol?gico, uma vez que seu estudo tem consequ?ncias diretas sobre o uso eficiente do espa?o urbano e a diminui??o da emiss?o de gases poluentes, contribuindo sobremaneira para o incremento da qualidade de vida. A pesquisa compreendeu desde a correla??o entre esse novo problema e outros constantes na literatura at? a concep??o de um conjunto de seiscentas inst?ncias artificiais e a cria??o de diversos m?todos de solu??o. Para a determina??o de ?timos, ? proposto um modelo matem?tico que suportou as solu??es por Programa??o Matem?tica e por Restri??es. Adicionalmente, ? apresentado um algoritmo branch-and-bound especificamente desenvolvido para o problema. Visando a busca por solu??es de qualidade em curto espa?o de tempo, s?o expostos cinco algoritmos experimentais com base nas abordagens heur?sticas Simulated Annealing, Variable Neighborhood Search, Coloniza??o de Abelhas e Algoritmos Gen?ticos. Diversos procedimentos auxiliares para constru??o de solu??es e execu??o de buscas locais s?o tamb?m expostos. Um experimento computacional ? realizado para compara??o entre os m?todos de solu??o. Uma amostra de cem casos teste ? utilizada para o processo estat?stico de ajuste de par?metros dos algoritmos heur?sticos, enquanto o restante das inst?ncias ? extensivamente abordado pelos m?todos. S?o determinados os ?timos para cento e cinquenta e cinco casos com tamanhos 10 e 20 cidades. Dentre os m?todos experimentais, cabe destacar a superioridade do algoritmo heur?stico que une as meta-heur?sticas Simulated Annealing e Variable Neighborhood Search. / The Traveling Salesman with Passengers and High Occupancy Problem is a version of the classic TSP where the salesman is the driver of a vehicle who shares travels? expenses with passengers. Besides shared expenses, the driver also benefits from discounts of the highoccupancy vehicle lanes, i.e. traffic lanes in which high occupancy vehicles are exempted from tolls. The addition of passengers to the TSP, a routing-only problem, creates a sharing view which is intensified by the consideration of special lanes. This scenario grants to the problem an ecological feature, since its study have direct consequences for the efficient use of urban space and the greenhouse gas emissions reduction, greatly contributing for quality of life improvement. This work addresses the study of this novel combinatorial optimization problem, going from the relationship it draws with other ones in the literature until the conception of a six hundred set of artificial test cases and the creation of many solution methods. To find optimal solutions, a mathematical model is proposed. This model supported the search for exact solutions by Mathematical and Constraint Programming. Additionally, is presented a branchand- bound algorithm specifically developed for the problem. Aiming the search for good quality solutions in short time period, five experimental algorithms based on the heuristics approaches Simulated Annealing, Variable Neighborhood Search, Bees Colony and Genetic Algorithms are introduced. Several auxiliary procedures for solutions generations and local search execution are revealed as well. A computational experiment is fulfilled to comparison between the solution methods. A sample of a hundred test cases is used for the heuristics algorithms? parameter tuning statistical process, while the rest of them are extensively addressed by the methods. The optimal solution for a hundred and fifty five test cases with sizes of 10 and 20 cities are determined. Among the experimental methods, one has to highlight the advantage of the heuristic algorithm that unites the metaheuristics Simulated Annealing and Variable Neighborhood Search.

In our society there is an increased awareness of environmental impact and reducing greenhouse gas emissions. An influencing factor is transport in passenger cars to and from work. In order to increase the utilization rate of passenger cars and thereby reduce environmental impact, a possible solution is to carpool. The purpose of the project was to create a web application to help those who want to carpool. To be effective and interesting to users such a web application needs to be useful and easy to navigate, as supported in previous surveys. The report’s issue is therefore how a carpooling web application, for companies and their employees, is designed and implemented to make it useful with regard to navigability. The attempt to answer the issue was initiated by finding relevant theory of navigabil- ity and usability. After that a market survey was conducted, to better understand the needs of the target group, and a prototype was developed based on the found theory. User stories were developed to define the application’s functionality and the development of the web application took place in parallel with iterative user tests, where feedback from the tests was implemented. At the end of the project, the final result and each user test were analyzed to compare users’ response to current theory and by answering the issue of the report. Based on the results of the tests, given the theoretical framework, it was shown that two out of four test subjects got lost in the web application. The test subjects were struggling to get through the buying process. They had insufficient understanding of what happens when placing a trip in the cart, that the trips are booked inside the shopping cart and that the payment of completed trips are found on the profile page. Reasons for the result may be due to both the weaknesses of the web application navigability or the characteristics of the test subjects. Despite this the web application was considered useful in accordance with the System Usability Test performed. In its entirety, the web application can be assessed as useful, though it can not be considered to meet the theoretical requirements for navigability. The conclusion is that a navigable web application can be developed by allowing users to effectively find the most important features of the web application. This can be imple- mented with a distinct navigation bar, visual indications for links, information boxes, a natural flow for the user through the page structure, and that the user can get through it with few steps. This should be specifically applied to the buying process, which is central to a consumer web application, to reduce perceived complexity and to be useful and navigable to the user. In order for the web application to be perceived as useful, it should contain the basic functionality requirements expected of a carpooling service. These are being able to register oneself, find a trip, create a trip, find information about pricing and to be able to remove a trip. / I samhället finns det en ökad medvetenhet kring miljöpåverkan och att minska utsläpp av växthusgaser. En påverkande faktor är transport i personbil till och från arbetet. För att öka nyttjandegraden av personbilar och därmed minska miljöpåverkan är en lösning att samåka. Syftet med projektet var att skapa en webbapplikation för att hjälpa de som vill samåka. För att vara effektiv och intressant för användarna behövde en sådan web- bapplikation vara användbar och lätt att navigera i, vilket stöds i tidigare undersökningar. Därför är rapportens frågeställning hur en webbapplikation för samåkning, för företag och dess anställda, designas och implementeras så att den är användbar med avseende på navigerbarhet. Besvarandet av frågeställningen inleddes med att relevant teori om navigerbarhet och användbarhet togs fram. Efter det gjordes en marknadsundersökning, för att tydliga- re förstå målgruppens behov, och en prototyp skapades utifrån den framtagna teorin. User stories användes för att definiera applikationens funktionalitet och utvecklingen av webbapplikationen skedde parallellt med iterativa användartester, där feedbacken från testerna implementerades. I slutet av projektet analyserades slutresultatet och varje enskilt användartest för att jämföra användarnas respons mot rådande teori, och genom det besvara arbetets fråge- ställning. Utifrån resultatet av testerna, sett till de teoretiska ramarna, visades det att två av fyra testpersoner var vilsna på webbapplikationen. Testpersonerna hade svårigheter att ta sig igenom köpprocessen. De hade bristande förståelse för vad som händer när man placerar resor i varukorg, att resorna bokas i varukorgen och att betalning av genomförda resor skedde på profilsidan. Anledningar till resultatet kan såväl bero på brister i web- bapplikationens navigerbarhet eller egenskaper hos testpersonerna. Trots detta ansågs webbapplikationen användbar i enlighet med de System Usability Test som utfördes. I sin helhet kan webbapplikationen därmed bedömas som användbar, däremot den kan inte anses uppfylla de teoretiska kraven för navigerbarhet. Slutsatsen dras att en navigerbar webbapplikation kan utvecklas genom att användar- na effektivt ska kunna hitta webbapplikationens mest väsentliga funktioner. Detta kan implementeras med en tydlig navigationsbar, visuella indikationer för länkar, informa- tionsrutor, ett naturligt flöde för användaren genom sidstrukturen och att användaren kan ta sig igenom den med få steg. Detta bör specifikt tillämpas i köpprocessen, som är central i en webbapplikation för konsumenter, för att minska upplevd komplexitet och att den är användbar och navigerbar för användaren. För att webbapplikationen ska upplevas som användbar bör den innehålla de grundläggande funktionalitetskraven som ställs på en samåkningstjänst. Dessa är att kunna registrera sig, hitta en resa, skapa en resa, hitta information kring prissättning och att kunna ta bort en resa.

Parking planning for new residential constructions is intensively discussed between develops, architects, and municipalities. In a big city, the land value is higher and it is more profitable to build apartments instead of parking places, but parking space can increase the value of the apartment. The purpose of this work was to analyse how the planning of a parking space in a big city compared to a smaller town differs today versus 10 years ago. Results of interviews were that the parameters such as municipal parking regulations and access to public transport govern the parking planning. All the municipalities, contractors and architects agreed that in the future more municipalities will work with flexible parking standards. The conclusion is that it is the municipality’s parking norm and access to public transport that affects parking planning. The largest change and development in the last 10 years is an increased investment into mobility solutions in form of charging stations and carpools.

The goal of this study was to develop Multinomial Logit models for the mode choice behavior of immigrants, with key focuses on neighborhood effects and behavioral assimilation. The first aspect shows the relationship between social network ties and immigrants’ chosen mode of transportation, while the second aspect explores the gradual changes toward alternative mode usage with regard to immigrants’ migrating period in the United States (US). Mode choice models were developed for work, shopping, social, recreational, and other trip purposes to evaluate the impacts of various land use patterns, neighborhood typology, socioeconomic-demographic and immigrant related attributes on individuals’ travel behavior. Estimated coefficients of mode choice determinants were compared between each alternative mode (i.e., high-occupancy vehicle, public transit, and non-motorized transport) with single-occupant vehicles. The model results revealed the significant influence of neighborhood and land use variables on the usage of alternative modes among immigrants. Incorporating these indicators into the demand forecasting process will provide a better understanding of the diverse travel patterns for the unique composition of population groups in Florida.

The purpose of our thesis was to examine citizens' attitude in a smaller city to new digital innovations, specifically autonomous vehicles and carpools, as well as opinions about citizens' participation. Through a web-based questionnaire, which was distributed on social media, as well as a discussion group on Facebook, an understanding was formed about the human acceptance, motivation factors, views and mobility habits. This was then analyzed to create an understanding of how a citizen dialogue should be conducted in social media. In line with this, we examined whether connections regarding human acceptance of new digital innovations can be affected, depending on how the dialogue is conducted and how much information the citizens are provided with. The result showed a clear relationship between knowledge and attitude, where a little knowledge created a more negative opinion. Other interesting discoveries that were identified, were that people see both problem areas and opportunities with a more digitized society. We also found how the respondents wanted increased participation, and that citizens' views are taken into account and have a clear impact on urban development. Finally, we conclude that the degree of citizens' participation and how the dialogue is conducted, shape their acceptance and understanding of changes in society and mobility solutions. The research area on human acceptance, participation and dialogue on autonomous vehicles and carpools is an emerging area of research. This means that the essay is exploratory which can enable further and more in-depth research. / Syftet med vår uppsats var att undersöka medborgare i en mindre stads inställning till nya digitala innovationer, specifikt autonoma fordon och bilpooler, samt åsikter kring medborgares delaktighet. Genom ett webbaserat frågeformulär, som distribuerades på sociala medier, samt en diskussionsgrupp på Facebook, bildades uppfattning kring människans acceptans, motivationsfaktorer, synpunkter och mobilitetsvanor. Sedan analyserades detta för att skapa en förståelse kring hur en medborgardialog bör föras i sociala medier. I linje med det undersöktes även samband om människans acceptans till nya digitala innovationer påverkas, beroende på hur dialogen förs och hur mycket information medborgarna tillhandahålls. Resultatet visade en tydlig relation mellan kännedom och inställning, där en liten kännedom skapade en mer negativ åsikt. Andra intressanta upptäckter som identifierades var att människor ser både problemområden och möjligheter med ett mer digitaliserat samhälle. Vi fann även att respondenterna önskade en ökad inkludering, samt att medborgares synpunkter beaktas och har en tydlig påverkan inom stadsutveckling. Avslutningsvis drar vi slutsatsen att graden av medborgarnas delaktighet och hur dialogen förs, formar deras acceptans samt förståelse för samhällsomställningar och mobilitetslösningar. Forskningsområdet kring människans acceptans, delaktighet och dialog kring autonoma fordon och bilpooler är ett växande undersökningsområde. Det gör att uppsatsen är explorativ vilket kan möjliggöra ytterligare och en mer djupgående forskning.

Placeringen av parkeringsplatser, för projekt med begränsad exploateringsyta, är ett välkänt problem inom den moderna byggnadsindustrin (Duvanova et al. 2016). Ytterligare är bullerstörningar ett problem för bostäder vilket ofta kräver innovativa lösningar, ofta I form av ljudreducerande element. Denna faktor är alltmer betydelsefull då bostadsområden har begränsad yta eftersom ljudkänsliga ytor på bostäders fasader, såsom gårdar, kan tvingas placeras mot ljusemitterande källor, såsom vägar. En undersökning utfördes angående ett nytt potentiellt bostadsområde I Ljungby kommun, år 2023. Undersökningen stötte på ett flertal problem angående planeringen av nya parkeringsplatser, samt ljudreducering på bostadens fasad, vilket inspirerade syftet avdenna rapport. Rapporten analyserade effektiviteten av flera parkeringslösningar såväl som bostadsformer i förhållande till kostnad, estetik och miljöpåverkan. Dessa typer av parkeringar var hydraulisk parkering, plan parkering, bilpool, parkeringshus ochparkeringsgarage. Plan parkering med delvis användning av bilpooler ansågs vara den effektivaste parkeringslösningen medan en U-formad byggnad, där parkeringsyta projekteras på första plan, anseddes vara mest effektiv med avseende på bullerreducering från trafik. Utnyttjandet av bilpooler anseddes vara en högt betydelsefull faktor för effektiviteten av denna lösning, eftersom implementering av bilpooler hade potentialen att spara upp till 5 miljoner kronor, teoretiskt sätt. Ytterligare undersökningar inom den praktiska tillämpningen av bilpooler inom bostadsområden med begränsad yta är därför högt rekomederat. / The placement of parking lots, for projects with limited available space, is a well-known problem in the modern building industry (Duvanova et al. 2016). Additionally, noise management is a problem for buildings that often requires alternative solutions, often in the form of noise canceling elements. This is even more prevalent when building residential areas with limited exploitation area, since noise sensitive areas such as courtyards are forced to be placed in close proximity to noise emitting areas, such as roads. An inquiry was conducted regarding a new residential area in Ljungby Municipality, Sweden year 2023. The study encountered multiple problems regarding parking lot allocation, as well as noise management on the building facade, which sparked the intent behind this study. This thesis work analyzed the effectiveness of various parking solutions, and building designs regarding the factors cost, aesthetics and environmental effects. The different types of parking solutions were hydraulic parking, plain parking, carpool, multistory carpark and parking garage. Plain parking was deduced as the most effective parking solution for the study while a U-shaped building, where a parking space was placed on the first floor, was considered to be most effective regarding managing street noise.  The utilization of carpools was considered to be a major factor in the effectiveness of this solution, since the utilization of carpools could lead to savings of up to 5 million Swedish crowns, in theory. Further investigations in the practical application of carpools in residential areas with limited space is therefore highly encouraged.
