The ISLES project intends to create an architecture for dynamic control of road lighting based on detected traffic. The following links refer to online information that might be relevant for such an architecture.

Positions of light poles

The architecture has to be a able to cope with different network configuration. For a number of cities, the positions of light poles are available through a GIS system (for example in the form of fault report system).

• Los Angeles, USA (116985 poles), available through the spatial information library of LA County.
• Washingthon DC, USA (66095 poles), available through Data Catalog of DC.
• San Diego, USA (48455 poles), available through SANDAG GIS Data Warehouse.
• Banff, Canada (744 poles)
• Nanaimo, Canada (3605 poles)
• Manhattan (707 poles)
• Amersfoort, Netherlands (28672 poles)
• Eindhoven, Netherlands (22500+ poles, partial, not official)
• Rotterdam, Netherlands (127413 light points, 103320 unique positions)

City and map information

To determine some characteristics of the (wireless) network, the communication model can include properties of the city, such as the type of area (park with trees, residential, industrial, shopping, ...), the locations of buildings, and the types of roads.

• OpenStreetMap (roads, usage and buildings)
• Mirror of Dutch map information, maintained by the Dutch OpenStreetMap site.
• Google Earth, Bing Maps
• Basisregistratie Adressen en Gebouwen, the Dutch building registration. With BAG viewer, you can access the data.

Traffic density and detection

In order to make the road lighting dynamic, the traffic has to be detected. The traffic density during the night provides information about the performance of the architecture with respect to energy savings and whether a solution is cost effective.

• DATEX-II, standard for exchange of traffic information, used in several European countries.
• Dutch traffic density during Easter 2011 at NDW, measurements for almost 20000 detection points during 7 days with a 1 minute interval. In DATEX-II format.
• TomTom traffic statistics, historic traffic database.

Related projects

Other projects are also investigating (dynamic) road lighting, although they might focus on a different topic.

• ENSURE, Dutch KWR project

Standards and organisations

The road lighting systems are often owned by local government and might be maintained by subcontractors. For safety reasons, the level of illumination is regulated by standards.

• CIE, International Commission on Illumination, which defines illumination standards.
• Inter Gemeentelijk overleg Openbare Verlichting, Dutch organisation for cooperation between cities on the topic of public lighting.
• Nederlandse Stichting voor Verlichtingskunde, Dutch organisation for illumination science, involved in regulation.
• New York Street Design Manual. Chapter 4 is on lighting.

Design of road lighting

When a residential area is developed, the road lighting is designed to take estetics, safety and regulations into account. The following software is related to such designs and provides light simulation.

• Calculux and Road Wizard
• DIALux
• ReluxSuite

Light pollution

Excessive road lighting results in light pollution, where incorrect installations and reflections cause the illumination of areas that are not targeted.

• Platform Lichthinder, Dutch platform for information on light pollution
• Nacht van de nacht, yearly Dutch event in October to reduce light pollution
• Detecting ET's city lights
• Nighttime Lights Posters, based on DMSP-OLS satellite data. The night lights are also used to determine economical developments.
