[CCTV design]Supposed customer give us so many intersection points, How to class

Hello, community!

Have a good day!

Supposed Customer gives us so many Intersection Points, How to classify these points and output  CCTV design model, let us have a look!

Solution

1. First  classify these points as for these intersection points;
   

2. For each type of  intersection points, give the design model; For example, for T-intersection, it's recommended to use 2BOX+1Dome camera to do the surveillance;
   

3. Intersection Points classification:

   The type of geometric configuration that best describes the intersection/junction.

• T-Intersection

• Y-Intersection
  

• Cross-Intersection (four legs)
  

• Five or more legs and not circular
  

• Roundabout
  

• Other circular intersection (e.g., rotaries, neighborhood traffic circles)
  

• Non-conventional intersection (e.g. superstreet, median U-turn, displaced left turn)
  

• Midblock pedestrian crossing
  

        
  

See Figure 6 for additional detail.

There are eight illustrations of different types of intersections in the figure labeled as T-Intersection; Y-Intersection; Cross-Intersection (four legs); Five or more legs and not circular; Roundabout; Other circular intersections (e.g., rotaries, neighborhood traffic circles); Non-conventional intersection (e.g., superstreet, median U-turn, displaced left turn); Midblock pedestrian crossing.

That is all, thanks!
