Traffic jams, pollution, road crashes: Can technology end the woes of urban transport?

Will technology be the savior of urban mobility?
 
Urbanization and rising incomes have been driving rapid motorization across Asia, Africa, and Latin America. While cities are currently home to 50% of the global population, that proportion is expected to increase to 70% by 2050. At the same time, business-as-usual trends suggest we could see an additional 1 billon cars by 2050, most of which will have to squeeze into the already crowded streets of Indian, Chinese, and African cities.
 
If no action is taken, these cars threaten literally to choke tomorrow’s cities, bringing with them a host of negative consequences that would seriously undermine the overall benefits of urbanization: lowered productivity from constant congestion; local pollution and rising carbon emissions; road traffic deaths and injuries; rising inequity and social division.
 
However, after a century of relatively small incremental progress, disruptive changes in the world of automotive technology could have fundamental implications for sustainability.
 
What are these megatrends, and how can they reshape the future of urban mobility?

Transit-oriented development — What does it take to get it right?

A recent trip to Addis Ababa really brought the imperatives of transit-oriented development as a complement to mass transit investments home to us. As a strategic response to rapid urbanization and growing motorization rates, Addis is one of several African cities currently developing public mass transit systems such as light rail and bus-rapid transit. Similar initiatives are budding in Dar es Salaam, Nairobi, and other cities in South Africa.

It is well known that transit-oriented development, or ToD, is a high-value complement to mass transit development. Compact, mixed-use, high density development around key mass transit stations can have the dual benefits of creating a ridership base that enhances the economic and financial viability of the mass transit investment and compounding the accessibility benefits a mass transit system can bring to a city’s residents. This is not to mention the intrinsic value in creating vibrant social gathering places for communities at strategic locations.

It doesn’t happen very often. Thank goodness. But there are times, very rare  times, when in our work, we experience a kind of mid-life crisis, when some external event sparks the realization that we have been traveling down a decision-path for so long, we’ve lost sight of something very important – when we stop and say, how did we get here?

It happened last month -- in Weihai, China’s Shandong Province, where we are working with the municipal government on the development of the city’s first Bus Rapid Transit (BRT) lines.
