1. 1. Distributed Trajectories under Mobile Phone Network: Empirical Estimation on Origin-Destination Matrix and Time-inhomogeneous Simulation

   Master-uppsats, Uppsala universitet/Statistik, AI och data science

   Författare :Liyuan Zhang; [2022]
   Nyckelord :;

   Sammanfattning : A trajectory is the movement of an object in space as time goes by,aka ‘spatiotemporal’. Aside from all the properties an ordinary trajectorypossesses, the primary characteristic of a distributed trajectoryis the uncertainty of its positioning. LÄS MER

3. 2. Path Choice Estimation in Urban Rails : Asimulation based optimisation for frequency-based assignment model

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Alexander Adolfsson; [2022]
   Nyckelord :Black-Box Optimisation; Optimization; Simulation based optimisation; Transit Network; Automaton; Urban Transport; Public transportation; Black-Box optimering; Optimering; Simuleringsbaserad Optimering; Transportsystem; Automation; Local Transport; Kollektivtrafik;

   Sammanfattning : Transit system have a large importance in modern urban cities, with urban rail often acting as the central system with it efficient travel time and great capacity. As cities grow in population, so to does the usage of urban rail resulting in increased crowding on the platform and in the trains. LÄS MER

4. 3. Optimizing the locations of bike-sharing stations using GPS-based trip data: A Spatio-temporal demand coverage approach

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Birkan Caliskan; [2022]
   Nyckelord :Geomatics; GIS; Bike-sharing; Genetic Algorithm; Location-allocation; Site selection; Optimization; Spatial Analysis; Earth and Environmental Sciences;

   Sammanfattning : Shared micro-mobility services are increasingly embraced by cities around the world in recent years. Their benefits over other transportation modes in certain frames encourage traffic/urban planners, public authorities to establish such systems in urban areas. LÄS MER

5. 4. Strategic passenger-oriented timetable design : Long-term timetable designs with minimised passenger inconvenience

   Master-uppsats, KTH/Transportplanering

   Författare :Yari de Graaf; [2021]
   Nyckelord :;

   Sammanfattning : Timetable development and design is a complex process that is crucial for safe and efficient railway operations. The combination of steel wheels and steel rails makes it possible to create trains and to transport many vehicles, thus passengers and freight, at the same time, but it also results in longer braking distances.

7. 5. Data-driven methods for estimation of dynamic OD matrices

   Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

   Författare :Ina Eriksson; Lina Fredriksson; [2021]
   Nyckelord :Large-scale mobility data; Dynamic OD matrix; Unsupervised learning; Sensor fusion; Kalman filter; Principal component analysis; Online estimation; OD estimation;

   Sammanfattning : The idea behind this report is based on the fact that it is not only the number of users in the traffic network that is increasing, the number of connected devices such as probe vehicles and mobile sources has increased dramatically in the last decade. These connected devices provide large-scale mobility data and new opportunities to analyze the current traffic situation as they traverse through the network and continuously send out different types of information like Global Positioning System (GPS) data and Mobile Network Data (MND).
