Looking at the statistics, I was horrified to learn how many pedestrians are killed each year in our cities. They are undoubtedly among the most vulnerable road users. My first question was how this could happen when we have the technology to prevent these tragedies. As accidents in spaces where vulnerable users meet vehicles often have tragic consequences, Schréder has developed specific and affordable solutions to improve safety there. The quality of the lighting of pedestrian crossings is directly related to the level of danger. Together with our stakeholders, we want to support cities in reducing road deaths, and we continue to invest to improve safety for all. Pedestrian fatalities are not inevitable

Our commitment Together for our Future Schréder has developed a cohesive, company- wide sustainability strategy called “Together for our Future”. This commitment is structured around three axes encompassing the relevant prioritised UN Sustainable Development Goals (SDGs). Sustainability is embedded into our strategy, structure, processes and culture. Working this way is the only way forward for truly positive and lasting benefits. Promoting active mobility and safety for all with the best lighting solutions on the market is a way to create sustainable value for communities.

Some key concepts A few things to know about pedestrian crossings

Vertical/horizontal illuminance

Horizontal illuminance

Vertical illuminance

Horizontal illuminance enables the pedestrian to see the road markings and to use the pedestrian crossing correctly. Vertical illuminance helps the motorist to see the pedestrian.

Some key concepts

A visible colour contrast

The contrast created by a different colour temperature from the surrounding road lighting is an effective way to highlight the pedestrian crossing and attract drivers’ attention.

10

Pedestrian in the driver’s eyes

In urban areas, the driver’s attention is naturally focused about 100 metres ahead, at an angle of about 5°. It is therefore important that the pedestrian appears early enough in his field of vision. Vertical illumination of the pedestrian should enable the driver to see the pedestrian and react accordingly. At 50 km/h, an average motorist needs about 43 metres to stop.

Regulations and standards What do the rules say?

Pedestrian crossings are sections of the road where good interaction between pedestrians and drivers is vital. The right lighting is essential to create the safest conditions for all.

12

Suitable lighting improves safety at pedestrian crossings, which need to be visible in various weather conditions and at all times of the day. It ensures the best conditions for drivers to understand the traffic situation and recognise the pedestrian’s silhouette, and makes pedestrians aware of their surroundings, the pedestrian crossing and approaching vehicles. The CIE gives recommendations and guidelines concerning the rules and levels for road lighting (including pedestrian crossings), as well as calculation procedures and methods of measurement. National standardisation bodies then convert these recommendations into local standards . At the international level, there is no harmonised definition for appropriate pedestrian crossing lighting and how to design it. However, existing regulations generally recommend a high level of contrast . They emphasise that pedestrians should be distinguished, mainly by the level of light intensity or the colour of the light.

Positive contrast solutions are favoured for pedestrian crossings illuminated by dedicated luminaires with asymmetrical light distribution . These luminaires have specific light distributions, adapted to the position of the luminaire, whether it is on the right or left side of the road and the direction of the traffic.

SOME BASIC PRINCIPLES APPLY GENERALLY:

- The horizontal illuminance on the pedestrian crossing should equal to 3 times the horizontal illuminance of the roadway at the edge of the crossing (but should be less than 4 times greater); - Horizontal and vertical illuminance calculation zones should extend over the full width of the roadway and the width of the pedestrian crossing, including waiting areas.

What’s next?

Towards a new dedicated approach

A working group including the Foundation for Civil Engineering Development, the Universities of Gdańsk and Warsaw, and the Research Institute of Roads and Bridges recently came up with guidelines for pedestrian crossing lighting (1) . This academic work proposes a specific way to maximise safety for pedestrians . They propose introducing new lighting classes (PC) for dedicated pedestrian crossing lighting solutions. Their purpose is to create a highly positive contrast for pedestrian silhouettes observed from the driver’s perspective.

This approach considers the luminance requirements of the road lighting class and the light reflected on pedestrians. These guidelines are not yet translated into regulations and standards, but might be soon, as normalisation bodies are currently busy revising their recommendations.

Maximising safety and visual comfort

ONE-WAY TRAFFIC

A single luminaire is able to light a pedestrian crossing for a one or two lane road, or a wide road including a bicycle track.

16

ONE-WAY TRAFFIC - 3 LANE ROAD

A second luminaire will be necessary on the opposite side of the road.

17

Our solutions

Specific optics available for a wide range of luminaires

More than half of all fatalities are due to traffic collisions that occur after dark, even though traffic is much lighter at night than during the day.

With quality lighting, the number of road accidents decreases by an average of about 30%, and by up to three times in the best conditions. The driver’s ability to spot danger and avoid accidents is compromised at poorly lit pedestrian crossings. Proper lighting significantly improves visibility, increases the driver’s field of vision, makes obstacles more visible and allows them to be detected earlier.

Schréder has a long history of success in improving the safety of pedestrian crossings. Our advanced LED technology, combined with our state-of-the-art optics designed specifically for these applications, provides the perfect photometries to help cities reduce the risk of accidents involving motorists and pedestrians.

20

Schréder designed LensoFlex ® 2 and LensoFlex ® 4 Zebra optics to meet the challenge of making pedestrian crossings safer while keeping the aesthetical consistency for lighting furniture in the urban landscape. has

Our dedicated optics provide visual comfort for both motorists and pedestrians to help them share the public space in a safer manner. The asymmetrical light distributions offer a high vertical illuminance level on the pedestrian from the driver’s position. At the same time, the pedestrian crossing itself receives a high horizontal illuminance level, revealing its position from a good distance.

White light combined with a sharp asymmetrical light distribution provides a very efficient solution for lighting pedestrian crossings. Our luminaires for pedestrian crossings have a high level of tightness (at least IP 66), in order to maintain the initial performance for as long as possible over the lifetime of the installation.

The bracket you need for a perfect result When the pole is located too far back from the street, post-top mounting is not ideal from a photometrical perspective. A bracket would be better to position the luminaire correctly and optimise the light distribution on the pedestrian crossing . With a wide range of more than 30 brackets, including contemporary and traditional designs, adapted to various luminaire mountings, Schréder can provide the ideal solution for you.

Real-time adaptation

With EXEDRA, Schréder relies on open standards and protocols to design an architecture able to interact seamlessly with third-party systems and platforms . A good example of this is what we offered to the City of Brussels. We provided themwith an innovative smart street lighting system along the ‘Bois de la Cambre’, a large urban park in the south of the city. There, we linked the luminaires to real-time data feeds in order to maximise safety, comfort and energy savings. This data was not captured by sensors installed on the luminaires but through online platforms on the Internet. Three types of existing and real-time data were used to trigger scenarios: • weather; • traffic; • location of pedestrian crossings. The data coming from the third-party platforms enabled the Schréder EXEDRA system to provide the optimal lighting levels at each light point and, if necessary, adapt the lighting every 15 minutes to real-time conditions.
