Passenger Car Equivalent for Heavy Vehicles Crossing Turbo-roundabouts
2016
Abstract Turbo-roundabouts represent an innovative scheme of modern roundabouts which provides a spiraling traffic flow and requires drivers to choose their direction before entering the intersection, since raised lane separators mark the lanes on the ring. The configuration of the turbo-roundabout makes that patterns of conflict at entries with one and two conflicting traffic streams can coexist. This paper presents research efforts aimed at measuring quantitatively the effect of heavy vehicles on operational conditions of a turbo-roundabout. The study starts from the initial belief that the greatest constraints to the vehicular trajectories imposed by the turbo-roundabout necessarily impl…
Stratégie du e-commerçant, accessibilité du produit et logistique urbaine
2013
Several factors impact urban logistics, among them, the recent evolution of e-commerce, by the new flows that it introduces in the city. It seemed interesting to us to understand urban logistics in this way, taking an original point of view, that of the upstream part of the logistics chain, namely the e-commerce strategy. We were thus able to highlight strategic and structural choices having consequences on product accessibility and urban logistics.
A Gamified Mobility Experience
2020
We believe in the use of urban games to define new enjoyable experiences, change citizens’ unsustainable habits and educate them to new environment-and social-friendly ones. This paper presents MUV, an innovative action that has the power to engage citizens and foster sustainable mobility behaviors. MUV complements engaging HMIs with a participatory method within an iterative innovation process called the virtuous cycle (understand, involve, co-create, implement, experiment). The innovation process has led to a new game dynamic: Mobility as a Sport. It results in a rewarding personal mobility experience; the same rewarding sensations the athletes feel when they improve their results.
Collaborative Content Downloading in VANETs with Fuzzy Comprehensive Evaluation
2019
Vehicle collaborative content downloading has become a hotspot in current vehicular ad-hoc network (VANET) research. However, in reality, the highly dynamic nature of VANET makes users lose resources easily, and the transmission of invalid segment data also wastes valuable bandwidth and storage of the users&rsquo
Mikromobilitātes klimata paplašināšanās iespējas Ziemeļvalstīs - iespējas un draudi
2020
Anton Martikainen rakstītajā maģistra darbā tiks pētīta mikromobilitāte, kas specializējas e-skūteros – šobrīd esošs fenomens, kas aizsākās 2018. gadā Amerikas Savienotajās Valstīs un ienāca Eiropā 2019. gada sākumā. Darba teorētiskā pieeja ir balstīta uz teoriju, kas saistīta ar paplašināšanos - mobilitāte kā pakalpojums un trešo pušu loģistikas teorija, kurai ir svarīga loma e-skūteru nozarē. Mikromobilitāte ir kļuvusi par aktuālu tēmu visā pasaulē, mainot veidu, kā cilvēki pārvietojas. Autors savā pētījumā definēs mikromobilitāti, analizēs galvenos tirgus dalībniekus un precīzi norādīs uz iespējām un draudiem un, kā tos redz iekšējās un ārējās iesaistītās puses. Darba izstrādes laikā tik…
Piegādes ķēdes vadības efektivitātes novērtējums mazumtirdzniecības zīmolos: IKEA piemērs
2020
Mazumtirdzniecības nozares uzņēmumiem piegādes ķēdes vadība ir svarīgs aspekts. Tomēr joprojām daudziem no tiem ir grūtības ar efektīvās piegādes ķēdes novērtēšanas sistēmas radīšanu un ieviešanu. Šī darba galvenais mērķis ir izveidot dzīvotspējīgu piegādes ķēdes novērtēšanas sistēmas modeli mazumtirdzniecības uzņēmumiem. Darba gaitā autors ir izpētījis un izanalizējis pieejamu literatūru par piegādes ķēdes pārvaldību un tās novērtēšanas sistēmas efektivitāti, izpētījis esošo piegādes ķēdes novērtēšanas sistēmu IKEA uzņēmumā, kas kalpoja par pētījumu objektu, kā arī veicis intervijas ar nozares ekspertiem piegādes ķēžu pārvaldībā. Rezultātā autoram izdevās identificēt un klasificēt radītāju…
Loģistikas sistēmas pilnveidošana SIA "DAW Baltic"
2017
Bakalaura darbā "Loģistikas sistēmas pilnveidošana SIA DAW Baltica" tiek analizēta uzņēmuma loģistikas sistēma, kā arī izstrādāti priekšlikumi tās pilnveidošanai un uzlabošanai. Tiek analizēta šī brīža transportēšanas sistēma, kā arī pasūtījumu atlases procedūras noliktavā. Darba rezultātā tiek secināts, ka sava transporta iegāde un uzturēšana konkrētajam uzņēmumam izmaksātu vairāk kā šī brīža ārpakalpojumu sniedzēju izmantošana. Analizējot preču atlasi pasūtījumam noliktavā, tiek secināts, ka ieviestā sistēma ir devusi uzlabojumus kļūdu skaita samazināšanai, taču to iespējams vēl vairāk uzlabot, modernizējot sistēmu. Darbā ir 56 lapaspuses, 7 tabulas, 16 attēli un 2 pielikumi.
Road Functional Classification Using Pattern Recognition Techniques
2019
The existing international standards suggest a methodology to assign a specific functional class to a road, by the values of some features, both geometrical and use-related. Sometimes, these characteristics are in contrast with each other and direct the analyst towards conflicting classes for a road or, worse, one or more of these features vary heterogeneously along the road. In these conditions, the analyst assigns the class that, by his capability and experience, he retains the most appropriate, in a very subjective way. On the contrary, the definition of an automatic procedure assuring an objective identification of the most appropriate functional class for each road would be desirable. …
A value sensitive ABM of the refugee crisis in The Netherlands
2019
We develop an agent based model to characterize the wellbeing of newcomers (i.e. asylum seeking refugees) in the context of asylum logistics using Schwartz’s theory of values. The model produces recommendations for decision-makers with respect to avoiding catastrophic outcomes and maximizing best case outcomes. We conduct analysis to show that while a relatively simple set of conditions is necessary to avoid catastrophic outcomes, these conditions are insufficient to maximize the best case outcomes. Furthermore, the conditions that maximize one best case outcome do so at the expense of another. The result is a platform for decision-makers to understand tradeoffs in policies for government a…
Agent-based modelling of values: the case of value sensitive design for refugee logistics
2020
We have used value sensitive design as a method to develop an agent-based model of values in humanitarian logistics for refugees. Schwartz's theory of universal values is implemented in the model in such a way that agents can make value trade-offs, which are operationalized into a measure of refugee wellbeing and a measure of public opinion about how the refugee logistics is being handled. By trying out different ‘value-scenarios’, stakeholders who are responsible for, or involved in refugee logistics can have insights into the effects of various value choices. The model is visualized and made usable as a platform (interactive website) for decision-makers to understand the trade-offs in pol…
