Traffic-condition analysis using publicly-available data sets

In this paper, we introduce some Dublin-specific public traffic data sets and analyse traffic data by linking it with other, non-traffic related datasets. We explain irregularities in observed journey times with weather phenomenas, public events and public holidays. We discuss how the timing of different weather phenomenas influences the observed journey time. By combining different data sources, we can provide reasoning for observed journey times which can be used to explain unexpected traffic patterns, improve capacity planning and aid with other traffic engineering tasks.
