4 1 Street Lighting Design and Installation Requirements 1.1 Glossary: ANSI/IESNA RP Illuminating Engineering Society of North America's American National Standard Practice for Roadway Lighting, issued June 26, Luminance Design a design based on the amount of light which is reflected from a surface and reaches the eye of the observer. It is based on the light the observer sees at a given point and is based on the reflectance of the surface and the angle and distance of the observer from the point observed. See RP-8-14, Annex A for further information on luminance. Illuminance Design - a design based on the amount of light which incident on a surface. Illuminance ignores the surface upon which the light falls. See RP- 8-14, Annex A4 for further information on illuminance. Pedestrian Conflict Area Classification Road classifications describe general conditions of vehicular traffic conflict in urban areas. A second type of conflict is the vehicular/pedestrian interaction. Pedestrian activity is nearly always related to the adjacent land uses. There are three levels of pedestrian conflict used by RP-8-14, high, medium and low. For the purposes of this manual, the pedestrian conflict level is assumed to be low for rural and low density urban areas. Medium for high density developments and adjacent to schools. Downtown locations are considered to be high density. High PC Areas are areas with significant numbers of pedestrians on the sidewalks or crossing the streets during darkness. Examples are downtown retail areas, areas near theatres, concert halls stadiums and transit terminals. Medium PC Areas are areas where fewer pedestrians use the streets at night. Examples are downtown office areas, areas with libraries, apartments, neighbourhood shopping and streets with transit lines. Low PC Areas are areas with low volumes of pedestrian traffic at night. Examples are suburban streets, low density developments and rural or semi-rural areas. See RP-8-14 for further information on pedestrian conflict classifications. Pavement Classifications Luminance calculations require information about the directional surface reflectance of the pavement. There are four general pavement classifications given in RP-8-14; R1, which is concrete or old asphalt pavement, R2, which is asphalt with a relatively high level of gravel or light coloured aggregate, R3, which is asphalt with a normal aggregate mix and normal age and wear this is the typical road classification for roads and the pavement classification to be used in Burlington unless otherwise directed by the City, R4, which is asphalt with very smooth texture that is mostly specular.

5 1.2 General: Street lighting design in the City of Burlington shall be generally based on ANSI/IESNA RP Street lighting design in Burlington must provide uniform lighting at a level that is adequate and comfortable for vehicular and pedestrian movement on the City s roads and sidewalks. All street lighting systems in the City of Burlington shall be designed by a qualified lighting designer using the luminance method as described in RP-8-14 (unless noted otherwise), as well as incorporating both the City s and Burlington Hydro s standards and specifications as given below. Street lighting design in Burlington must take into consideration all of the approved luminaires of a given type in order to allow interchangeability of luminaires during maintenance operations. maximum spacing or arrangements given in the following sections are to be used for the specific cross section or road layout shown. Variations in cross section, road layout and/or pedestrian conflict levels must be dealt with on an individual design basis, with a specific lighting design and associated calculations submitted to the City for review. It is the responsibility of the street lighting designer to ensure they have the latest revisions of the City of Burlington s street lighting standards and specifications and a current list of approved suppliers prior to designing a street lighting system. As of January 1, 2003, all street lighting design and construction is subject to Electrical Safety Authority (ESA) inspection and approval. All materials used for street lighting in the City of Burlington must meet CSA specifications. Street lighting luminaires to be installed on Burlington Hydro poles shall have Ontario Regulation 22/04 documents and drawings prepared and submitted to Hydro for approval. Decorative street lighting may be used in the City only with the City s permission and in accordance with the City s requirements and specifications. 1.3 Replacement and Upgrade Policy: New installations shall be designed and constructed in accordance with the specifications contained in this manual wherever possible. Where the designer wishes to use materials or specifications not contained in this manual, they must first contact the City to obtain their approval. It is the policy of the City that damaged or destroyed street light poles, luminaires, etc. shall be replaced with materials in accordance with the new standards. 1.4 Downtown Lighting Policy: The downtown area of the City is considered unique and requires special consideration. There is in general a high level of pedestrian activity in the downtown area, particularly during the numerous special events that occur in the summer months. In view of this, the

6 specific lighting design criteria are set out for the downtown area. Table 1 is for vehicular traffic and table 2 for sidewalks and pedestrian walkways. It is the policy of the City that all street and sidewalk lighting design shall be based on ANSI / IESNA RP-8-14 as referred to above.

Vertical illuminance aids facial recognition. All lighting designs for the downtown area must be submitted to the City for review with necessary back-up material, included but not limited to shop drawings, lighting design photometric analysis data, cross sections, etc. Where the City s standard cross sections are not applicable, the designer shall submit an appropriate road cross section(s) and the proposed road and pedestrian conflict classifications to the City for review. No design shall proceed without the City s approval of the road and pedestrian conflict classifications.

7 2 Illuminance and Luminance Design Criteria The design requirements for luminance and illuminance given below in Tables 3 and 4 are taken from ANSI/IES RP The values given for luminance shall be used for all roadways. The values given for illuminance are for use in intersection and sidewalk designs. For the purposes of lighting design in the City of Burlington, it was assumed that the pedestrian conflict area classification with the exception of downtown area is low. All roads requiring a medium or higher pedestrian conflict designation will require the preparation and submission of a suitable design to the City for review.

Therefore illuminance criteria and calculations are recommended for use in the design of intersections. Intersections should be illuminated to a level equal to the sum of the recommended average illumination levels for each of the intersecting roads. These levels are given in Table 4, above. A pedestrian conflict classification of low is included in the illumination levels given in table 4. No further adjustment of lighting levels

14 is required due to pedestrian conflict classifications unless a higher classification is required. 2.4 ESA Lighting Design Requirements The new ESA regulations came into effect as of January 1, These regulations are intended to separate the street lighting system from the electrical distribution system and to allow parties other than the local distribution company to maintain street lights. In order to accomplish this, a lighting designer must place a service entrance rated disconnect between the electrical distribution system and the street lighting system. The method approved by the City of Burlington at this time is to run an appropriately sized service cable to a street light pedestal (see City of Burlington Dwg. No. S-156) and from there to the individual street lighting circuits. A maximum of a 5% voltage drop will be allowed in the street lighting cable from the transformer to the last light in the circuit. All materials, including the secondary service to the disconnect switch, must be CSA approved and will be subject to ESA inspection and approval. 2.5 Curves and Hills Tables 6 and 7, Maximum Spacing on Straight Sections for the two types of luminaire/pole combinations, are to be used on relatively straight and level sections only. When lighting curves and/or hills, the spacings in the aforementioned tables should be modified in accordance with the procedures given in ANSI/IES RP-8-14 in Section Cul-de-Sacs There are several design criteria to be addressed when designing lighting for the end (bulb) of cul-de-sacs. These are: The area to be lit is not readily adaptable to the standard luminaires used in Burlington; The space available for the placement of the luminaires/poles is generally quite limited due to the convergence of driveways in the boulevard areas; and Due to the basic assumptions inherent in luminance design and the methods used in its calculation, the use of luminance criteria at the ends of cul-de-sac (or any other dead-end arrangement) is not recommended. Illuminance criteria and calculations are recommended for use in the design of cul-de-sac, as specified in Table Lighting in Cul-de-Sacs It is suggested that lighting in cul-de-sacs be arranged in accordance with the sketches given below.

15 Option A Option A consists of a street light placed as close as possible to the neck of the bulb with two street lights tilted at 5 at the top of the bulb at an angle of 0 + / - 5 off the north line. The luminaire wattage and pole size are to match the luminaire/pole combination specified for the type of street. (See Table 4 for appropriate illuminance levels). Option B Option B consists of a street light placed as close as possible to the neck of the bulb, with two street lights tilted at 5 at angles of 45 + / - to 70 + / - from the top center of the bulb. The luminaire wattage and pole size are to match the luminaire/pole combination specified for the type of street. (See Table 4 for appropriate illuminance levels).

16 Designs for street lights using arrangements other than the standard locations given above shall be accompanied by a full set of lighting calculations for review and approval by the City. 3 Material Specifications All street lighting equipment used in the City of Burlington must meet the current City of Burlington s street lighting standards and specifications. It is the responsibility of the street lighting designer to ensure they have the latest revisions of the City s street lighting specifications and list of approved suppliers prior to ordering any materials. All street lighting components are to be manufactured in strict accordance with the City s current requirements. 3.1 Street Light Poles Street light poles used in the City of Burlington must be manufactured in accordance with the City s street light pole specifications as given below. 3.2 Cobra Head Luminaire/Pole/ Bracket Combinations In general, the following cobra head luminaire/pole combinations with lamps shall to be used in the City of Burlington.

26 4 Adaptive Lighting With the development of new lighting technology and effort to reduce the overall energy and environmental impact of lighting, adaptive lighting has become a new trend in the roadway industry. Adaptive lighting is a design methodology in which the light output of a system is adjusted as traffic conditions change. More specifically, roadway lighting illumination levels are adjusted based on the needs of the roadway s users. The level of lighting can be reduced or dimmed when traffic on roads, sidewalks, or both is reduced. Dimming the lighting level while maintaining the lighting configuration will not affect the uniformity of the lighting or an object s contrast; however, contrast thresholds will increase, resulting in longer detection times. In addition, luminaires installed in new lighting designs often exceed the requirements of the lighting design. Over time, the system will meet or exceed the design level even as the lamps age and dirt accumulates on lenses. Adjusting the output of luminaires so the system meets the design level throughout the service life of the lamps can also save on energy costs and eliminate periods of over-lighting. This form of lighting control is not specifically considered adaptive lighting, but an adaptive lighting system provides this option. The overall objective of adaptive lighting is to reduce lighting levels on roadways During Periods of Low Traffic Density. Some of the issues to consider are: Optimal times and conditions for reducing lighting. Appropriate lighting levels for various roads and road features. Appropriate approaches for reducing lighting. Energy savings and reduction in greenhouse gases that may result from reducing lighting. Potential legal issues related to reducing lighting, including the development of such. The size of the area of the lighting system to be adapted must be considered. Dimming of the roadway system can occur broadly over all the roadways within a given area, or selective dimming of sections of the roadway network can be implemented, based on an analysis of needs. In general, dimming a large area will maintain a constant lighting level throughout the roadway so that drivers will not experience a bright lighting condition on one roadway and then turn onto a dark roadway and be forced to significantly transition their eye adaptation level, which can be uncomfortable and dangerous. However, dimming a large area may also cause some areas to be too dark. It is recommended that each street be evaluated in terms of its lighting needs. However, the difference in lighting classes for streets in a given vicinity should be no greater than two. It is also recommended that residential areas be adapted to a single lighting level. For roadway facilities, each roadway should be assessed individually, but drivers should not experience greater than a two-level change in the lighting class. Transitions on roadways should be a maximum of 1 class per mi of travel

27 5. Installation Specifications 5.1 General The contractor shall ensure that the construction and installation of a street lighting system will be completed in a high quality manner and in accordance with the latest revisions of the specifications, standards and drawings of the City of Burlington. Street lights shall be located on the boulevard in accordance with the City of Burlington s standard cross sections and as shown on the trenching plans and typical road sections, while maintaining proper clearances from fire hydrants, driveways, transformers, switching units and trees or any other services. The street lighting power supply is to be supplied to each streetlight loadcentre in accordance with Burlington Hydro U/G electrical distribution specs. The entire street light installation is subject to inspection and approval by the ESA. The contractor is responsible for applying and obtaining said inspection. Burlington Hydro will make the connections inside the transformer once the following steps have been fulfilled: Approval has been given by the ESA, and a Connection Authorization has been received by Burlington Hydro. City Engineering Inspection will also require a copy of the ESA authorization for the City s records. The contractor has arranged for a Megger testing of the system, and a copy of the successful test report has been submitted to the City Engineering Inspector and the Supervisor of Traffic Operations. The Supervisor of Traffic Operations has sent a request for connection letter to Burlington Hydro. Burlington Hydro shall notify the City Engineering Inspector and the Street light Coordinator once the street light system connection at the transformer has been completed. The City Engineering Inspector shall then energize the streetlight system at the loadcentre and inspect the system operation. Any deficiencies shall be reported by the Inspector to the contractor for rectification. 5.2 Cable Street light cables shall be installed in conformity with Burlington Hydro s Underground Electrical Distribution specifications. The cable shall be installed in 50 mm Type II PVC, direct buried duct with a minimum of 600 mm cover. As per the Electrical Code, a 150mm wide red plastic warning tape is to be installed with black lettering stating ELECTRIC LINE BURIED BELOW. This warning tape is required to be installed midway between the topmost conductor and final grade above all conductors within the trench. Where the street light poles are not in place at the time of the cable installation, the end of the cable shall be coiled and staked at the intended pole location in a similar manner to the secondary service cables except that at least 3 m of cable shall be left above grade. Where the cable is to continue on to another street light, the cable shall be looped and not cut, and at least 6 m in total shall be left above grade.
