Temporary signage and pedestrian safety

Temporary signage always starts with a basic concept: advance notice . Drivers must understand what's happening and how traffic will change before they arrive at the construction site: lane narrowing, one-way traffic, detours, speed limits. Signs placed too close to the construction site don't leave drivers time to react, especially on fast roads.
Beyond distance, the consistency of the message matters. A logical sequence—works sign, road narrowing warning, speed limit, and any alternate one-way traffic—allows drivers to gradually adapt their behavior. Conflicting signs, hidden behind trees, knocked over by the wind, or obscured by parked vans, create confusion.
Pedestrian safety requires specific measures. When sidewalks are occupied by construction sites or excavations, it is necessary to clearly indicate alternative routes: diversions on the opposite side of the road, protected corridors, temporary crossings. Simple tape is not enough; stable barriers, ramps to overcome differences in level, and signs visible even to those with mobility or visual impairments are needed.
At night or in low-visibility conditions, illuminated signs come into play: flashing lights, headlights, and reflective elements on barriers and fences. A properly lit construction site makes obstacles visible even in the absence of natural light, reducing the risk of collisions with vehicles and tripping pedestrians. The light should not dazzle drivers, but should clearly guide the route.
Intersections, bus stops, and schools require even greater attention. These areas have high pedestrian density, shorter reaction times, and greater distractions. Well-placed signs, continuous barriers, and protected crossings help maintain a clear separation between construction sites, traffic, and pedestrian flows, especially during rush hour.
An often overlooked aspect is the maintenance of temporary signage throughout the construction site: wind displaces cones and signs, rain fades them, and vehicles can hit the barriers. Periodic checks to realign, clean, and replace damaged items are an integral part of the job, not a courtesy.
When temporary signage is carefully designed and managed, pedestrians and motorists perceive the construction site as a controlled area, not a chaotic obstacle. This, in addition to improving safety, helps reduce tension and complaints from those who pass by the construction site every day.
Highlight
• Well-designed signage informs drivers and pedestrians in advance of what is happening and how routes are changing.
• Protected pedestrian paths, corridors and temporary crossings increase the safety of pedestrians.
• Flashing lights, reflective elements and luminous signs improve the visibility of the construction site even in the evening.
• Orderly and consistent signage reduces unnecessary slowdowns and sudden vehicle maneuvers.
Low Light
• Poorly positioned, covered or windblown signs generate confusion and unpredictable behavior.
• Temporary signs must be checked and maintained: if neglected they quickly lose their effectiveness.
• At critical points (intersections, bus stops, schools) more attention and on-site checks are needed.
