Urban experts say building more streets in Mexico City does not protect pedestrians because current infrastructure lacks intuitive safety design [1].
This failure in urban planning suggests that increasing road capacity may exacerbate risks for those on foot rather than mitigating them. As the city grows, the disconnect between road expansion and pedestrian safety creates a systemic danger for millions of residents.
Pedestrians are currently the second most vulnerable group in Mexico [1]. Experts said that the danger persists because street designs rely on speed limits or individual responsibility rather than physical infrastructure that naturally protects the user [1], [2].
Jimena David, an expert on the subject, said that a truly safe system requires deep transformation [1]. This transformation involves moving away from car-centric growth and toward designs that prioritize human movement over vehicle throughput.
Addressing these risks requires a shift in how public space is allocated. Brisa Bujakiewicz said that the redistribution of public space and pedestrianization are key to reducing the effects of excessive traffic [3].
Without these changes, adding more lanes or roads may simply encourage more traffic, increasing the potential for accidents in areas where the environment is not designed to keep pedestrians safe. The current model prioritizes the flow of cars, which often leaves those walking in precarious positions [1].
Experts said that safety cannot be achieved through regulations alone. Instead, the physical environment must be altered to intuitively guide drivers and protect walkers, ensuring that the layout of the city itself prevents collisions [1], [2].
“Pedestrians are currently the second most vulnerable group in Mexico.”
The critique of Mexico City's infrastructure highlights a global urban planning conflict between 'induced demand'—where more roads lead to more traffic—and the 'Vision Zero' philosophy, which posits that human error should not result in death. By identifying pedestrians as the second most vulnerable group, the data suggests that the city's growth strategy has prioritized vehicular mobility over basic human safety, necessitating a fundamental redesign of public spaces to reduce fatalities.
