Methodology

The LANTERNS project has four components:

1. Nationwide analysis of street level data

We are collecting information on the locations of all streetlight reduction schemes in England & Wales. Using police data on crime and road traffic crashes we will examine how often crime and crashes occur on roads before and after streetlight was reduced, and we will compare this with crime and crashes on roads where streetlight has not been reduced at night. We will statistically assess whether, and, if so, by how much, crime and road traffic crashes change on roads where streetlight is reduced at night.

2. Public views of streetlight and reduction schemes

This component explores local public opinion about streetlight in 8 local authorities chosen to reflect a range of areas across England & Wales. We are gathering information on public views obtained from websites, interviews with key stakeholders, and one-to-one conversations with residents living in areas where streetlight has been reduced at night.

3. Costs and benefits of streetlight reduction schemes

We are collecting data on the costs of providing street lighting. Then, using data generated in components 1 & 2, we will compare the societal costs of streetlight reduction to the societal benefits, using a cost-benefit analysis framework.

4. Stakeholder engagement

We are engaging with all local authorities of England & Wales to create an ongoing dialogue about the ways in which this research on streetlight reduction is useful. We are planning to convene a Stakeholder Workshop in October 2014 and we would welcome input from everyone with an interest in the LANTERNS project. We also plan to make resources on streetlight reduction accessible to local authorities as the data become available.
