A review of techniques to extract road network features from global positioning system data for transport modelling

With the spread of smartphones and mobile internet, Global Positioning System (GPS) data from vehicles has become widely available. This data represents a unique opportunity to automatically extract road network features and generate detailed maps that can be used in the creation of transport network models, while minimising the quantity of resources usually invested in that task. Accurate transport network models can be used in a variety of applications either in transport simulation models or autonomous vehicles navigation. Although two relevant literature reviews were performed during the last decade, they were not systematic and did not explore the road network inference methods from a transport network modelling point of view. The objective of this research is to perform a systematic and reproducible literature review on the use GPS data in transport network modelling and provide limitations and future work to extract a road network representation for transport models and autonomous vehicles navigation. This was done by systematically examining the studies' different approaches with respect to relevant criteria. Most studies produced a simple representation of the road network, not detailed enough for transport models. Other limitations were the bias introduced by the GPS sample and the reproducibility of the different methods.

Automated summary

With the popularity of smartphones and mobile internet, GPS data from vehicles has become widely available. This data provides a unique opportunity to automatically extract road network features and generate detailed maps for transport network models, reducing the usual resource investment. However, current studies lack systematic exploration and evaluation of road network inference methods from a transport network modelling perspective. This research aims to address this gap by conducting a systematic and reproducible literature review on the use of GPS data in transport network modelling, highlighting limitations and future work for road network representation in transport models and autonomous vehicles navigation.
