In this paper we present an algorithm to build a road network map enriched with traffic rules such as
one-way streets and forbidden turns, based on the interpretation of already detected and classified
traffic signs. Such algorithm helps to automatize the elaboration of maps for commercial navigation
systems.
Our solution is based on simulating navigation along the road network, determining at each point of
interest the visibility of the signs and their effect on the roads. We test our approach in a small urban
network and discuss various ways to generalize it to support more complex environments.

Luaces, MiguelVarela-Rodeiro, Tirsohttp://dspace.infodocu.lbd.org.es/xmlui/handle/123456789/13992025-10-20T11:13:21Z2018-01-01T00:00:00ZStoring and Clustering Large Spatial Datasets Using Big Data Technologies
Cortiñas, Alejandro; R. Luaces, Miguel; Varela-Rodeiro, Tirso
In this paper we present the architecture of a system to store,
query and visualize on the web large datasets of geographic information.
The architecture includes a component to simulate a large number of
drivers that report their position on a regular basis, an ingestion component that is generic and can acommodate three different storage technologies, a query component that aggregates the results in order to reduce
the query time and the data transfered, and a web-based map viewer. In
addition, we define an evaluation methodology to be used to benchmark
and compare different alternatives for some components of the system,
and we validate the architecture with experiments using a dataset of 40
million locations of drivers.
