Can compact rail transit corridors transform the automobile city? Planning for more sustainable travel in Los Angeles

Directing growth towards compact rail corridors has become a key strategy for redirecting auto-oriented regions towards denser, mixed-use communities that support sustainable travel. Few have examined how travel of near-rail residents varies within corridors or whether corridor land use–travel interactions diverge from regional averages. The Los Angeles region has made substantial investments in transit-oriented development, and our survey analysis indicates that although rail corridor residents drove less and rode public transit more than the county average, households in an older subway corridor with more near-transit development had about 11 fewer daily miles driven and higher transit ridership than households along a newer light rail line, a difference likely associated with development patterns and the composition and preferences of residents. Rail transit corridors are not created equally, and transit providers and community planners should consider the social and development context of corridors in efforts to improve transit access and maximise development.

The declining role of the automobile and the re‐emergence of place in urban transportation: The past will be prologue

The dominant view among transportation scholars is that transportation history flows from older to newer travel modes, with each mode being superior to and, for the most part, displacing the earlier modes. America, an early adopter of widespread automobility, was in this view a harbinger of trends that would follow elsewhere, and hence the US experience of passenger travel based almost completely on car travel was a signal of things to come. Yet this paper argues that interpreting from the US experience with the interstate highway era misses key points. The interstate system, and the planning that surrounded it, was developed during a brief period of time when transportation policy was centralized, standardized, and largely divorced from questions of local impacts and place‐based political pressures. That made the years immediately after the 1956 Interstate Highway Act unusual in the broader context of transportation planning. The US has recently witnessed a return of pre‐interstate urban transportation planning realities, and transportation in large US cities is now multi‐modal, contextualized by ties to land use and neighbourhoods, and fraught with the politics and incrementalism of the pre‐interstate era. Regional science research, grounded in the era of national highway construction, can adapt to the realities of modern urban transportation planning by focusing more on collaboration and financing in ill‐defined institutional settings, environmental externalities and non‐market impacts, and retrospective project evaluation.
