1. Generating Road Traffic Information Based on Cellular Network Signaling
Sammanfattning : Cellular networks of today generate a massive amount of signalling data. A large part of this signalling is generated to handle the mobility of subscribers, irrespective of the subscriber actively uses the terminal or not. Hence it contains location information that can be used to fundamentally change our understanding of human travel patterns. LÄS MER
2. Transport Analytics Based on Cellular Network Signalling Data
Sammanfattning : Cellular networks of today generate a massive amount of signalling data. A large part of this signalling is generated to handle the mobility of subscribers and contains location information that can be used to fundamentally change our understanding of mobility patterns. LÄS MER
3. Analysis of Travel Patterns from Cellular Network Data
Sammanfattning : Traffic planners are facing a big challenge with an increasing demand for mobility and a need to drastically reduce the environmental impacts of the transportation system at the same time. The transportation system therefore needs to become more efficient, which requires a good understanding about the actual travel patterns. LÄS MER
4. Methods for Travel Pattern Analysis Using Large-Scale Passive Data
Sammanfattning : Comprehensive knowledge of travel patterns is crucial to enable planning for a more efficient traffic system that accommodates human mobility demand. Currently, this knowledge is mainly based on traffic models based on relatively small samples of observations collected from travel surveys and traffic counts. LÄS MER
5. Data-Driven Approaches for Traffic State and Emission Estimation
Sammanfattning : Traffic congestion is one of the most severe problems in modern urban areas. Besides the amplified travel times, traffic congestion intensifies the amount of emitted pollutants impacting human health and the environment. LÄS MER
