Latest company news about Selection of Weigh-in-Motion (WIM) Station Locations

1. Site Selection
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  0 Prioritize locations on major freight routes with steady traffic flow and convenient law enforcement access:
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  1 National/provincial trunk highways, major county roads, expressway entrances/exits, provincial and municipal boundaries
Exits of large mining areas, ports, logistics parks, building material markets and other cargo sources.
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  1 Approaches ahead of large bridges and long tunnels (for structural protection of bridges and tunnels).
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  3 Locations to avoid: Urban downtown areas, sections with dense traffic signals, sharp curves and steep slopes.
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  4 General principle: Vehicles shall pass through at a constant speed on a straight and smooth road without braking, accelerating or lane changing.
2. Road Alignment (Critical for Measurement Accuracy)
(1)Horizontal Alignment
The station shall be installed on a straight road section, with a straight stretch of no less than 200 meters ahead and behind the detection zone.
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  5 Prohibited locations: Curves, ramps, overpass approaches and road diverging/merging sections.
(2) Pavement Smoothness
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  1 Within 35 meters ahead and behind the detection zone, the pavement roughness shall be within ±3 mm. No potholes, cracks or loose surface shall be present.
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  3 The density of asphalt or concrete pavement shall meet relevant standards. Pavement patches are not allowed, especially directly above sensors.
(3) Road Gradient
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  1 Longitudinal and transverse gradients shall both be no greater than 2% and keep uniform.
τα τελευταία νέα της εταιρείας για Selection of Weigh-in-Motion (WIM) Station Locations  4 The gradient shall remain consistent for no less than 35 meters ahead and behind the detection zone; a minimum of 25 meters is acceptable under budget constraints. Sections at the bottom/crest of slopes or grade change points are strictly prohibited.
