Urban mobility is essential to creating sustainable cities. It impacts not only environmental pollution levels but also productivity and access to key services.
An effective urban mobility strategy necessitates high-quality public transit that reduces congestion while being seamlessly integrated into city fabric, and less reliance on cars that produce sound pollution and air pollution.
Transportation
Urban mobility underpins everything that people do as individuals and communities, forming the basis for regional and international economic expansion. Furthermore, it shapes cities as desirable places for businesses and residents alike – but unfortunately today’s urban transportation systems are overburdened and unsustainable.
Transportation is the fourth-highest contributor of greenhouse gas emissions worldwide and traffic congestion and air pollution are major quality-of-life detractors. Furthermore, climate shocks like heat waves or floods threaten mobility by cutting people off from economic opportunities.
To improve urban mobility, we must shift the way we think about travel. From a long-term perspective, this requires shifting our modal share (the proportion of trips made via different transport modes) in order to address safety, sustainability and accessibility – three primary concerns regarding urban mobility. An essential step toward this end should be encouraging active modes of transport such as walking and cycling as key ways of improving urban mobility; other solutions could include car-sharing platforms or MaaS platforms which integrate shared mobility services with traditional vehicle ownership into one convenient app experience.
Commutes
Commuting may be associated with individual travel to and from work, but its definition has expanded significantly over time to encompass trips within urban areas. Many census surveys such as the American Community Survey collect commute data in order to assist city planners and policymakers understand travel demand, anticipate infrastructure pressures and identify unmet transportation needs.
Trip generation is an integral component of urban mobility, and temporal variations in trip frequency may depend on activity space or access to amenities. Socio-economic status also plays a factor, with those lacking public transit options or high automobile ownership costs having an increased tendency towards making more trips than their peers and becoming “mobility-deprived” residents.
Cities serve as hubs of regional, national and international economic and social development; consequently they experience increasing travel demands in their central zones, suburbs and between. Cities face the daunting task of making sure their systems are safe, accessible, affordable, smart resilient and emissions free – this requires new mindset and willingness to disrupt current practices in favor of more efficient modes of transport.
Suburbs
Suburbs, in general, are residential areas located outside a city center that have lower population densities and more emphasis on privacy than urban areas. Suburbs became increasingly popular after World War II when families began leaving overcrowded cities for cheaper yet safer living options; this movement came to be known as “white flight”, and has had lasting ramifications on demographic trends.
Suburbs can either fall within city limits or exist as separate municipalities that are annexed into a larger metropolitan area, like Cambridge, Massachusetts and Berkeley and Oakland in California are considered suburbs even though they reside within their respective city’s city limits. Furthermore, in countries like India, China and Argentina new suburban developments often become part of larger metropolitan areas as time progresses.
Most suburban systems feature an intricate web of streets that connect each block via collector roads, increasing travel times to work for residents of these communities.
Transit-Oriented Development
TOD (transit-oriented development), an increasingly popular trend of urban planning that centers urban places and communities around high quality public transit systems, is part of a solution to global issues like climate change and energy security. By creating vibrant walkable neighborhoods that reduce car usage as well as fossil fuel dependence, TOD allows people to enjoy full lives free from car ownership hassles and expenses.
Urban mobility and city planning have always gone hand in hand, from trackside suburbs built alongside streetcar or rail lines to New York’s “Terminal City,” built around Grand Central train station. However, limited public transportation and high vehicle ownership costs limit mobility for a large portion of people in many locations.
Emerging mobility services, like multimodal transport and MaaS, allow commuters to select among a range of traditional transit modes such as buses, tramways, trains and ferries within one app that calculates the most cost-effective and time-efficient journey for each trip.
