Residential land use density regulation is an important policy instrument for reducing the local external diseconomies caused by concentration of population and buildings in urban areas. But density regulation also affects the distribution of population across the whole urban space, which determines the travel demands hence traffic flows over the transportation network in the city. In this paper, we formulate a model integrating the residential location choice equilibrium, traffic network equilibrium and the housing market equilibrium, subject to floor area ratio (FAR) regulation, a representative practical strategy for density regulation. The restriction of FAR regulation on housing supply is formulated as a development coordination cost function dependent on the level of FAR that is actually realized under the designated upper FAR limit. Complementary location-specific tax/subsidy policies, and road pricing schemes, are also addressed in a unified manner.

优化城市居住用地和交通网络管理的监管和财政政策

居住用地密度调控是减少城镇人口和建筑集中造成的地方外部不经济的重要政策工具。但密度调控也会影响整个城市空间的人口分布，从而决定出行需求，从而决定城市交通网络的交通流量。在本文中，我们建立了一个集成住宅区位选择均衡、交通网络均衡和住房市场均衡的模型，并受容积率（FAR）调节，这是密度调节的代表性实用策略。容积率监管对住房供应的限制被制定为开发协调成本函数，取决于在指定容积率上限下实际实现的容积率水平。补充性的特定地点税收/补贴政策以及道路定价方案也以统一的方式解决。
