1. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography
University essay from Umeå universitet/Institutionen för fysikAbstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE

2. Simulation of road traffic flow in Hangzhou
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissions by changing the traffic signal programs.

3. Integration of Open Data in Disaggregate Transport Modelling : A Case Study of Uppsala
University essay from KTH/TransportplaneringAbstract : Transport models are key in predicting travel behaviour and planning transport systems. Transport models can be either aggregated or disaggregated. Disaggregation means that travel behaviour is represented on an individual level, which can be beneficial because it offers a higher detail level and reduces aggregation bias. READ MORE

4. Quality Assessment of OpenStreetMap Footpath Data
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This project assesses the feasibility of reconstructing virtual cities from OpenStreetMap (OSM) road and building data, and will focus on the feasibility of including pedestrian footpaths. It will be examined how common it is that footpaths overlap with other map features such as roads and buildings. READ MORE

5. Map-aided localization for autonomous driving using a particle filter
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Vehicles losing their GPS signal is a considerable issue for autonomous vehicles and can be a danger to people in their vicinity. To circumvent this issue, a particle filter localization technique using pre-generated offline Open Street Map (OSM) maps was investigated in a software simulation of Scania’s heavy-duty trucks.
