Abstract

Transit-oriented development (TOD) has been recognized as an effective measure to alleviate traffic congestion and emissions through improving land-use intensity. However, excessively high land-use intensity could cause a decrease in inhabitation comfort. To ensure the inhabitation comfort at a certain level, floor area ratio (FAR) regulation has been widely applied in the property development of many megacities worldwide. This paper proposes an analytical model to address the issues of TOD investment and FAR regulation in a transportation corridor. Based on a formulation of multi-modal urban system equilibrium with auto and rail competition, a social welfare maximization model is presented to determine the optimal scheme for TOD investment (number, location and size of TOD zones) and FAR regulation. The trade-off between improved accessibility and decreased inhabitation comfort due to TOD investment is incorporated in the model. A case study of Dongguan city, China is also conducted for model illustration. Insightful findings are reported on the interrelationships among the TOD investment, FAR regulation, travel mode choice, and urban spatial configuration as well as their implications in practice.
