Why are some street lamps switched off at night?


Lower electricity costs, lower CO2 emissions: with the two and a half hour night-time shutdown of the street lighting, the city saves and makes a contribution to climate protection

The street lights are only switched off for two and a half hours - and not, as is often assumed, for the entire night. The nights before Saturdays, Sundays and public holidays are excluded. As a result, the city can save 125,000 euros per year. Why is this happening? In 2012, the City Council of Moers commissioned the city administration to identify all potential savings against the background of the emergency budget. A specific suggestion from politicians was to switch off the lights at night. The administration has previously examined various options. This included, for example, the use of energy-saving light sources, dimming street lighting, switching off every second light or switching the lighting on later and off earlier. The result was that the temporary night shutdown is the most economical way to save electricity costs in the short term. At the same time, it is environmentally friendly. As the public discussion has shown that there are always misunderstandings on this topic, we have put together some of the most important questions and answers.

When was the night shutdown started?

The first shutdowns took place in September 2014. By March 2015, the comprehensive shutdown in Moers was implemented. The shutdown took place from north to south, i.e. starting in Kohlenhuck via Repelen, Rheinkamper Ring, Eicker-Wiesen, Utfort, Eick-West etc. to the end in Vennikel.

On what days and at what times are the street lights switched off?

The street lighting is switched off Monday through Friday between 1 a.m. and 3:30 a.m. The street lights remain on completely on weekends and public holidays.

Are all lights switched off?

No. Pedestrian crossings and danger spots are further illuminated.

How expensive is the conversion and what is the saving? (Status: 08/12/2014)

The costs for installing the night shutdown are around 180,000 euros (one-time). The savings in electricity costs amount to around 125,000 euros per year. The savings increase with an increase in the price of electricity.

What effects does the night shutdown have for climate protection?

The CO2 emissions are reduced by approx. 600 tons per year. For comparison: With the equivalent of around 11 tons per year In Germany, greenhouse gases are on average significantly higher than the global per capita volume of around 6.8 tonnes.

Have cities had negative experiences with night shutdown?

There was no impact on both road safety and crime in cities that temporarily switch off the street lights at night (e.g. Meerbusch or Rheine).

Why can't you just switch off every 2nd street lighting or do without switching off in certain areas?

Since this results in a quick change between light and darkness, the eyes have to constantly adjust to the change in light and can then no longer recognize obstacles that suddenly appear despite the driving lights. This affects traffic safety. In addition, the measure is not economical because the renovation costs are high and the savings effect is comparatively low.

Why is dimming the lighting not an alternative?

This only works with the same luminaires in the network. Fluorescent lamps are much more difficult to dim than LED lights, sodium vapor lamps or energy-saving lamps. All four lamps are in use in Moers.

How is the project technically implemented?

The lighting is controlled via a central computer in the town hall. That can be changed at any time.

Can't the savings also be achieved through the widespread use of LEDs?

LED retrofitting plus night shutdown saves the most electricity in the long term. A complete conversion of the street lighting to LED would cost the city of Moers around three million euros. That is why the lighting is gradually being upgraded. By the end of the year, ten percent of the street lighting in Moers will have switched to LEDs.

What do drivers have to consider?

There is a standardized marking on the lights that are switched off at night. Here, the vehicle owner must make his vehicle recognizable for other road users. This is done by switching on the parking lights.

Signs from the road traffic regulations:

38Sign 394Explanation

Lantern ring
In built-up areas, the symbol indicates lanterns that do not light up all night. In the red field it can be indicated in white letters when the lantern goes out.

How much does the parking light load the car battery?

Barely. With today's batteries, there are usually no problems, as the consumption of the parking light is very low.

Are there also areas that remain continuously lit?

Since switching off the street lighting at night must not lead to a deterioration in road safety, this has been checked separately. In addition to ensuring the road safety obligation, special danger points and fear areas were the focus of the test.

By switching off the street lights, vehicle drivers have to adapt their driving behavior to the situation (lower speed, increased attention). However, pedestrians must still be able to use the footpaths safely without lighting. This means, for example, that pedestrians in the traffic area do not have to expect planters. During a night drive and inspection in Scherpenberg and Meerbeck under cloudy skies, for example, sufficient visibility was found. This also applied to pedestrians, who were able to spot built-in structures such as curbs, plant beds, etc. in good time. An objective reason for feelings of fear could not be noticed.

Further exams:

Special traffic areas

  • Accident sites The last 5 years were examined to determine whether poor visual relationships or clarity were a decisive criterion. If this is the case, the street lighting, if any, remains switched on continuously.
  • Level crossingsthat are used by passenger and freight traffic in regular operation remain illuminated. They should be visible to the vehicle driver at an early stage.
  • Railway underpasses are perceived by the majority as a dread dream and often represent a bottleneck in the transport network. Therefore, these remain continuously illuminated.
  • Anxiety dreamsKnown as such in the urban area, such as the train station area or the Royal Court, remain illuminated throughout.
  • Fire stations in principle do not require any special street lighting. Continuous lighting may be necessary depending on the location in the street.
  • Hospitals are continuously illuminated. Street lighting is therefore not required.
  • Pedestrian zones have a large number of obstacles (planters, benches) as well as stairs and ramps. During a nightly inspection (around 2.30 a.m.) it was found that a large number of shops are continuously illuminated. From a traffic point of view, continuous street lighting is only necessary in special danger areas (risk of falling on stairs, etc.).
  • Roundabouts can often only be recognized as such at a late stage in the dark and also represent points of orientation. Therefore, these must be illuminated continuously.
  • Spatial orientation points: In places of particular traffic importance or streets without special signs such as roundabouts, LSA or similar, it may be necessary to illuminate landmarks (e.g. Moers train station, Markt Repelen)

Zebra crossing/FGÜ

Pedestrian crossings with zebra crossings are to be continuously illuminated according to the directive.

Traffic lights / traffic light systems (LSA)

At the traffic lights, which are already switched off at night, the street lighting remains on continuously. Traffic lights, which can only be seen late due to their location, are also continuously illuminated. At all other traffic lights, the street lighting is turned off at night.

Bus stops

The bus stops, which are already lit today and are still served after 1:30 a.m., must be lit continuously (waiting halls or street lights).
