Study Notes
Road Classification
- Class I roads are for competition play in large capacity areas and stadiums with up to 200,000 spectators, requiring 1500 lux lighting.
- Class II roads are for competition play with fewer than 5,000 spectators, requiring 1000 lux lighting.
- Class III roads are for recreational and competitive play, with a focus on players but also considering spectators, requiring 750 lux lighting.
- Class IV roads are for recreational and social play only, with secondary consideration for spectators, requiring 300-500 lux lighting.
Road Types
- Expressways are roads reserved for motor traffic, accessible only from interchanges with no crossings at grade.
- Major Roads are part of a roadway system that serves as the principal network for through traffic flows, connecting areas of principal traffic generation.
- Collector Roads are distribution and collector roadways servicing traffic between major and minor roadways, used mainly for traffic movements within urban areas.
- Minor Roads include subdivision roads and local roadways used primarily as access roads to residential areas, commercial buildings, and industrial plants, with minimal through traffic.
- Rural Highways are provincial roads that serve as the principal network for through traffic in rural areas.
Lighting Luminaire
- Type III Medium Semi Cutoff High Pressure Sodium (HPS) luminaire, or its equivalent, shall be used for roadway lighting.
Lamp and Ballast
- Lamp and ballast shall operate within the range of voltage-current characteristic parameters that are compatible with each other.
- Retrofit control gear shall have a power factor of 0.9 and above, and the total harmonic distortion (THD) of 15% and below.
Grounding
- Equipment shall be grounded in accordance with the latest edition of the PEC.
