1. 1. Modelling and Simulating Demand-Responsive Transport

   Författare :Sergei Dytckov; Jan A. Persson; Paul Davidsson; Erik Jenelius; Malmö universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Demand Mobility; Demand Responsive Transport; Modelling and Simulation; Sustainability;

   Sammanfattning : Public transport is an efficient way to transport large volumes of travellers. However, there are systemic issues that make it hard for conventional public transport to provide efficient service on finer levels, like first- and last-mile problems or low-demand areas. LÄS MER

3. 2. Heat Transport from On-demand Single-Electron Sources

   Författare :Nastaran Dashti; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluctuations and noise; thermoelectric devices; energy-selective detector; single-electron source; charge and heat currents;

   Sammanfattning : The controlled injection of quantized charge excitations from single-electron emitters into nanoscopic conductors sets the basis for many important applications ranging from metrology to the emerging field of quantum optics with electrons. Successful implementation of these applications relies not only on achieving control on the precision of the particle emission, but also on the energetic properties of the injected particles.

4. 3. Exploring societal impacts of self-driving public transport using four-step transport models

   Författare :Erik Almlöf; Mikael Nybacka; Erik Jenelius; Mia Hesselgren; Clas Rydergren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-driving vehicles; Public transport; Four-step transport model; Societal impacts; Sampers; Machine Design; Maskinkonstruktion;

   Sammanfattning : During the last decade, self-driving technology has become increasingly visible in the news, with the vision that people would enter vehicles that drive themselves, and that people could instead rest, read the newspaper, or have a meeting. However, these visions have mainly focused on the potential for car usage, even though public transport could benefit greatly from self-driving technology. LÄS MER

5. 4. Diagnosing Sharing Anxiety

   Författare :Sigma Dolins; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ridehailing; sharing anxiety; shared autonomous vehicles; ridepooling; on-demand transport; qualitative methods; shared autonomous public transport; autonomous vehicles; public transport;

   Sammanfattning : Numerous studies indicate that the potential of autonomous vehicles (AVs) to reduce greenhouse gas emissions, reduce traffic congestion, and increase mobility access can only be fully realized through fleets of vehicles being used for shared rides, also known as dynamic ridepooling. This has the potential for transforming the public transport industry, as well as how transportation functions in urban and rural contexts. LÄS MER

7. 5. Uncertain demand prediction for guaranteed automated vehicle fleet performance

   Författare :Sten Elling Tingstad Jacobsen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility-on-Demand; Travel Demand Uncertainty; Energy Efficiency; Chance Constraint Optimization; Gaussian Process Regression; Stochastic Model Predictive Control; Fleet Opti- mization;

   Sammanfattning : Mobility-on-demand (MoD) services offer a convenient and efficient transportation option, using technology to replace traditional modes. However, the flexibility of MoD services also presents challenges in controlling the system. One of the major issues is supply-demand imbalance, caused by uneven stochastic travel demand. LÄS MER
