Why More Cities Should Close Their Streets To Cars

Every summer, cities astir nan world big car-free days and temporarily pedestrianize streets. Following their occurrence elsewhere successful nan world, impermanent pedestrianized streets are becoming much communal successful North America, specified arsenic for ample sporting events, taste festivals and farmers’ markets.

This year, arsenic portion of nan FIFA World Cup, immoderate cities successful North America created pedestrianized instrumentality zones for spectators and visitors. In Vancouver, nan metropolis pedestrianized a ample agelong of Granville St. successful nan downtown core.

Doing truthful tin thief support section businesses, springiness nationalist spaces backmost to group and retrieve them from cars. The City of Vancouver precocious announced that Granville St. will stay pedestrianized until astatine slightest September.

Pedestrianized streets emerged successful Europe much than 7 decades ago. The 2 astir notable precedents are Lijnbaan successful Rotterdam and Strøget successful Copenhagen. Despite apprehension from immoderate business owners and a number of drivers, galore occurrence stories person put those concerns to remainder while often exceeding expectations.

These streets person proven to beryllium awesome draws for pedestrians and cyclists, yielding accrued economical activity without needing to inefficiently give nationalist spaces to backstage vehicles. Critics often interest that pedestrianization simply shifts postulation elsewhere. While nan effects dangle connected section design, galore cities person recovered that immoderate trips vanish altogether arsenic group move routes, recreation modes aliases destinations.

Pedestrianized streets are often evaluated economically, but their wellness benefits person acold little attention. Our caller study astatine Carleton University measured aerial and sound contamination knowledgeable by group stepping and cycling on Ottawa’s Queen Elizabeth Driveway (QED), pinch and without nan beingness of vehicles.

What we found

The QED is portion of nan National Capital Commission’s Bikedays program, which temporarily provides agelong stretches of its scenic roads to group connected ft and bike. The programme dates backmost to 1970, making it a pioneer.

However, contempt extended hours during nan COVID-19 era erstwhile downtown residents different lacked recreational abstraction and nan adjacent pathways were overcrowded, nan hours person since go restricted to daylight hours connected weekends.

The QED presents a peculiarly enticing investigation opportunity because nan roadway is exclusively unfastened to pedestrians and cyclists connected definite play hours successful nan summer. Accordingly, a near-perfect earthy research allows nan effect of vehicles to beryllium measured.

We measured particulate matter and ultrafine particles (both of which are produced by cars and person galore wellness consequences) and sound astatine 12 measurement stations on nan roadway.

Traffic sound is not conscionable nan astir annoying root of sound successful cities; it’s affecting semipermanent health. Measurements on nan QED from a operation of weekdays and weekends and astatine 3 times per time showed that aerial contamination was typically astir 70 per cent higher erstwhile cars are present, while perceptible sound was astir 50 per cent higher.

The beingness of this sound whitethorn make nan quality betwixt being capable to person a comfortable speech and having to outcry and strain to listen. Similar results were recovered successful different studies, specified arsenic New York City’s Highline, which is an above-ground railway that has been converted to a pedestrian pathway.

Researchers recovered sound and aerial contamination were almost 40 per cent little connected nan Highline comparative to nan thoroughfare level. The effect of contamination and sound is peculiarly acute for stationary roadworthy users, specified arsenic diners astatine patios, who cannot easy move retired of harm’s way.

The early of pedestrianization

Some mightiness deliberation that caller technologies for illustration electrical vehicles will absolve vehicles of sound pollution. However, EV sound tin attack nan level of gas-powered vehicles — particularly supra astir 50 kilometres an hr — owed to tyre noise, aerial turbulence and horns. And while EVs destruct tailpipe emissions, their heavier weight results successful greater tire-related particulate emissions.

The wellness and information benefits of pedestrianized streets widen good beyond aerial contamination and noise. Without vehicles, collisions pinch group are virtually eliminated.

In 2023, one-quarter of nan 1.2 cardinal world roadworthy postulation deaths were pedestrians and cyclists who died aft being deed by drivers. Not only are those deaths tragic, but nan perceived risks forestall group from taking up cycling.

There are galore beingness and intelligence wellness benefits to stepping and cycling. Ensuring that our cities person ample, pleasant and safe spaces to do so, peculiarly pinch entree to amenities, would beryllium a captious measurement guardant for nationalist health.

As YouTuber Jason Slaughter of nan transmission Not Just Bikes erstwhile said: “Cities aren’t loud; cars are loud.”

While nan implementation specifications of pedestrianization are important, uncertainty should not beryllium feared. Pedestrianized streets use people, businesses and nan planet. It’s clip to rethink our cities, particularly nan astir car-centric ones.
