Case Study: How Improved Signage for Pedestrians and Cyclists Reduced Accidents by 40%

Executive Summary / Key Results

This study documents the successful implementation of a comprehensive program to improve signage for pedestrians and cyclists in the city of Valencia, Spain. The results demonstrated a 40% reduction in accidents involving vulnerable road users in the intervention zones, a 25% increase in respect for crosswalks, and a 35% improvement in perceived safety among cyclists. The investment of 150,000 euros generated an estimated social return of 2.1 million euros over five years, avoiding medical costs, property damage, and productivity losses.

Background / Challenge

In 2021, Valencia faced a growing problem: while active mobility (pedestrians and cyclists) was increasing, so were traffic incidents involving them. City Hall data showed that between 2019 and 2021, accidents involving pedestrians had increased by 18% and those involving cyclists by 22%. Particularly concerning were poorly marked pedestrian crossings and intersections where cyclists shared space with motor vehicles without clear demarcation.

The main challenge was twofold: on one hand, drivers did not always properly identify pedestrian priority zones or bike lanes; on the other, pedestrians and cyclists often were unaware of their rights and obligations on public roads. An analysis of 50 critical points revealed that 68% of crosswalks lacked complementary vertical signage, and 45% of bike lanes were not properly marked at intersections.

Solution / Approach

The implemented solution was based on three fundamental pillars: improved signage, integrated road safety education, and supporting technology. For pedestrian signs, the installation of S-22 type vertical signs (pedestrian crossing) complemented by high-visibility road markings was standardized, including zebra crossings with integrated LED lighting at 15 main intersections. For cyclists, specific signage was implemented that included warning signs for the presence of cyclists (S-24), mandatory bike lane use signs (R-407), and horizontal signage with red bicycle pictograms.

An innovative component was the implementation of "shared zones" with speed limited to 20 km/h, marked with S-860 signs, where pedestrians, cyclists, and vehicles share the space with absolute priority for pedestrians. These zones were complemented with informational signs explaining the coexistence rules.

To better understand the regulatory context, it is helpful to review our article on Señales de Obligación: Qué Debes Hacer, which details the signs that every driver should know and respect.

Implementation

The implementation was developed in four phases over an 18-month period. The first phase consisted of a detailed diagnosis that identified 120 critical points through accident data analysis, direct observation, and user surveys. The second phase involved designing specific solutions for each type of problem, working with urban mobility experts and representatives from pedestrian and cyclist associations.

The third phase was the physical execution, which included:

• Installation of 85 new S-22 signs (pedestrian crossing)
• Renovation of 120 zebra crossings with high-durability thermoplastic paint
• Implementation of 45 S-24 signs (presence of cyclists)
• Creation of 8 shared zones with complete signage
• Installation of 12 LED lighting systems at pedestrian crossings

The fourth phase consisted of a parallel educational campaign that included workshops for professional drivers, informational material distributed in driving schools, and collaboration with local media to disseminate the new rules.

Results with specific metrics

The results were measured through direct observation, surveys of 500 users, and analysis of official traffic data. The following table summarizes the main indicators before and after implementation:

A specific case that illustrates the program's success is the intersection of Calle Colón with Avenida del Cid. Before the intervention, this point recorded an average of 5 annual accidents with pedestrians. After installing a zebra crossing with LED lighting, a large S-22 sign, and approach road markings, no accidents have been recorded in the last 18 months. Surveys reveal that 92% of drivers now clearly identify the area as a pedestrian priority zone.

The return on investment was calculated considering not only the reduction in accidents but also public health benefits (increased walking and cycling), reduced congestion, and improved quality of life. The cost-benefit analysis showed that for every euro invested in signage, 14 euros in social benefits were generated.

Key Takeaways

This case study offers several valuable lessons for other cities and organizations interested in improving road safety:

1. Integrated signage is more effective: Combining vertical signs, road markings, and lighting elements multiplies the effectiveness of each element separately.

2. Education must accompany infrastructure: Installing signs is of little use if users do not understand their meaning. The parallel educational campaign was crucial to the success.

3. Data guides decisions: Data-based identification of critical points allowed for optimized resources and maximized impacts.

4. User participation is essential: Involving pedestrian and cyclist associations in the design ensured that solutions addressed real needs.

5. Technology complements traditional signage: Elements such as LED lighting at crosswalks significantly increase nighttime visibility.

These principles align with best practices in road signage, as detailed in our article Señales de Tráfico y Marcas Viales: A Complete Guide, which offers a comprehensive view of the signage system.

About Examen de Manejo

Examen de Manejo is the leading platform for driving test preparation in Spanish, with over 500,000 monthly users. Our mission is to train responsible, safe drivers who are knowledgeable about traffic rules. Through updated content, exam simulations, and educational resources, we help drivers not only pass their exam but also develop safe driving habits for life.

This case study is part of our commitment to road safety and driver education. We believe that understanding real cases of safety measure implementation helps drivers comprehend the importance of each traffic sign and rule.
