Methods for street lighting visualization and computation in 3D interactive platform
A system and corresponding method is disclosed for monitoring and conducting large-scale performance verification of a city's lighting infrastructure. In particular, the current invention combines measurements of lighting performance measurements along city roadways with regulatory requirements for the roadways. In various embodiments, the current invention then presents a three-dimensional visualization of the 5 adequacy of existing roadway lighting with respect to these regulatory requirements.
1. A method of managing compliance with lighting requirements for one or more sections of a roadway surface, wherein the one or more sections includes one or more lights, the method comprising:
collecting light measurement data and corresponding GPS determined locations associated with each collected light measurement;
creating a display depicting one or more sections of the roadway;
determining for a given section of the roadway its classification;
obtaining the regulatory lighting lux standard for such a classification;
determining each sections' level of compliance with regulatory lighting requirements based on the classification; and
visually depicting on the display the level of compliance for one or more sections of the roadway; and
determining an estimated light luminance value at each test point by performing a weighting function on at least one location's light measurement data, the weighting being based on the location's proximity to the test point.
2. The method of claim 1 , further including the step of adjusting the one or more lights based on the level of compliance in a respective section.
3. The method of claim 1 wherein said visually depicting step comprises shading or color coding to indicate the one or more sections' level of compliance.
4. The method of claim 1 wherein the display is a three dimensional (3D) display and said visually depicting step comprises superimposing onto the 3D display an indication of at least some of the luminance values, wherein the magnitude of at least some of said luminance values are indicated by vertical lines.
5. The method of claim 4 wherein the 3D display indicates by line style or color of the vertical lines associated with one or more sections of the roadway, the level of compliance of each depicted section.
6. The method of claim 1 further comprising:
determining positions of light poles along the given section of the roadway and indicating these positions on the display; and,
indicating on the display test points relative to the light pole positions, which test points being required by the regulatory requirements.
7. The method of claim 1 further comprising:
depicting on the display, an average lux reading using estimated light luminance values determined for a section of the roadway; and,
providing an indication on the display whether the section of the roadway meets the lighting lux standard, based upon the average lux reading.
8. The method of claim 1 further comprising:
depicting on the display, a minimum lux reading for estimated light luminance values determined for a section of the roadway; and,
providing an indication on the display whether the section of the roadway meets the lighting lux standard, based upon the minimum lux reading.
9. A computer program product comprising a plurality of program code portions, stored in a non-transitory computer readable medium, for carrying out the method according to claim 1 .
10. The method of claim 1 , wherein the classification includes one or more of road names, road type, including a highway or residential road, and the shape of the road.
11. A system for of managing light luminance values measured at locations along one or more sections of the roadway surface, wherein the one or more sections includes one or more lights, the system comprising
a central processor;
a mobile device equipped with GPS functionality for obtaining light luminance values along one or more sections of a roadway and the locations at which those values were obtained;
a communication system operably connecting the central processor and the mobile device;
a database including the classification of the one or more sections of the roadway and the regulatory lighting lux standard for each roadway classification;
a display device for depicting a display of one or more sections of the roadway; and,
wherein the central processor determines each sections level of compliance with regulatory lighting requirements based on the classification and causes the display to visually illustrate the level of compliance for one or more sections of the roadway;
the central processor determines an estimated light luminance value at each test point by performing a weighting function on at least one location's light measurement data, based on the location's proximity to the test point; and,
wherein the estimated light luminance values are used in determining compliance with regulatory requirements.
12. The system of claim 11 further comprising:
the central processor determines positions of light poles along the given section of the roadway and indicates on the display, test points relative to the light pole positions, which test points being required by the regulatory requirements.
13. The system of claim 11 further comprising:
the display depicts an average lux reading using estimated light luminance values determined for a section of the roadway; and,
the display provides an indication on the display whether the section of the roadway meets the lighting lux standard, based upon the average lux reading.
14. The system of claim 11 further comprising:
the display depicts a minimum lux reading for estimated light luminance values determined for a section of the roadway; and,
the display provides an indication on the display whether the section of the roadway meets the lighting lux standard, based upon the minimum lux reading.
