Topic analysis of Road safety inspections using latent dirichlet allocation: A case study of roadside safety in Irish main roads.

Under the Safe System framework, Road Authorities have a responsibility to deliver inherently safe roads and streets. Addressing this problem depends on knowledge of the road network safety conditions and the number of funds available for new road safety interventions. It also requires the prioritisation of the various interventions that may generate benefits, increasing safety, while ensuring that reasonable steps are taken to remedy the deficiencies detected within a reasonable timeframe.

Red light cameras revisited. Recent evidence on red light camera safety effects.

The aim of this paper is to update the most recent published evidence on road safety estimates of recent red light camera (RLC) and speed/red light camera studies (SRLC). A literature search was carried out on RLC studies in the period 2013-2017 which, after screening, identified 18 recent studies on red light cameras (RLCs) and speed/red light cameras (SRLCs). The methodology and results of these studies were further examined and summary safety estimates were derived and compared to earlier meta-analysis summary estimates.
