Abstract
The claimed benefits of dynamic speed limit (DSL) strategies (e.g. increase of throughput or speed homogenization) still remain as a controversial topic. The present paper presents an empirical assessment of DSL policies with aggregated traffic flow data. A DSL system installed on the C-32 metropolitan freeway accessing the city of Barcelona (Spain) since February 2009 allows a before-after comparison between non-DSL and DSL scenarios. In order to achieve this objective, a new methodology is pro...
