Get following data from the table：
Maximum illumination =40.2(Lx)
Minimum illumination =12.8（Lx）
Average illumination=∑A/N≈20.7（Lx）
Uniformity Ratio=Minumum illumination/Average illumination≈0.62
3) According to the requirement of "CJJ45-2006 urban road lighting design standards", the cement road of small and medium-sized city's traffic control system and road distribution perfect facilities, main trunk road average illumination require not less than 14Lx, uniformity ratio requires not less than 0.4. The actual measurement of the average illumination and uniformity indicators are superior to those requirements.
