Dense, mixed-use, walkable urban precinct to support sustainable transport or vice versa? A model for consideration from Perth, Western Australia

Abstract

Within the majority of the literature on sustainable transport, it is accepted as ideal to arrange new urban growth in close proximity to major public transit services. While the literature on this subject of transitoriented developments (TOD) is positive and optimistic, for the most part such assertions are conjectural. This article will attempt to fill this gap by revealing a modeling process undertaken for a local area's reurbanization project to understand the potential and limitations of several modes of transport to support the increased activity density in the precincts. Several of the most standardized policy levers were employed, such as parking ratios and mix of use and building height, and contrasted with the trip generation and transit mode's hourly capacity to reveal potential real-estate yields. The outcomes indicate not only the immediate yields but also the capacity for urban transformation due to each level of sustainable transport investments. The model is unique in that the capacity, parking ratios, and assumptions are highly transparent. KEYWORDSTransit oriented development; urban land and transportation modelling

Spatiotemporal Changes in Vertical Heterogeneity: High-Rise Office Building Floor Space in Sydney, Australia

“…By the 1990s, the concept of mixed-use planning became one of the community design principles of new urbanism, the compact city ideal, and sustainable development [9,10]. Hendrigan and Newman [11] also illustrated that mixed-use planning can reduce travel distances between workplaces and residences, reducing car dependency. Shim et al [12] emphasised that mixed-use development minimises urban sprawl by using available land with a combination of residential, retail, and offices.…”

Optimizing Land Use Allocation of Transit-Oriented Development (TOD) to Generate Maximum Ridership

“…The transit ridership optimization approach derived from the required per person space requirement in a building has been applied by Hendrigan and Newman [68] in modeling the daily trips to estimate the capacity of transit mode in providing services for a dense, walkable and mixed-use area in Perth, Australia. Their research resulted in an estimation model of additional real estate yields obtained from a function of parking lot reduction and high transit mode capacity.…”

The Trackless Tram: Is It the Transit and City Shaping Catalyst We Have Been Waiting for?

“…Considering the potential for slowing urban sprawl in Perth a proposal [29] to develop a new 25 km transit corridor with 12 stations stands to reduce the need for development on the fringes from 100 km 2 to 65.7 km 2 of urban re-development-see Table 2. Hendrigan and Newman [30] estimate that some 30 years of urban growth could be accommodated in and around new and revived transit stations if a program of light rail was introduced to complement the new heavy rail and was associated with such station precinct-focussed urban regeneration. Similarly, Thimphu, a city of 26 km 2 , plans to accommodate population growth from 100,000 to 400,000 people calling for the city to quadruple in size.…”
