可交易信用证已被公认为一种强有力的工具，并在许多领域得到越来越多的使用。本文通过一种新型的公共道路私人融资方式--建设股权信贷（BEC）计划，将可交易信贷计划应用于交通流动性管理和私人提供公共交通基础设施，以期实现三赢。也就是说，政府可以实现其目标（如建设新的道路，期望的交通条件，一定的车辆排放阈值）没有自己的资本，私人公司可以获得其预期的利润与公众的阻力较小，旅行者可以享受较少的拥挤的交通，可以忽略不计的成本。此外，在传统的私人融资（例如建造-运营-移交）计划结束后，许多问题，如严重的拥堵，交通需求爆炸和缺乏管理和维护，都可以在BEC中避免。建立了一个一般的双层规划问题来模拟BEC方案中新道路的通行能力和可交易信用方案的确定。几个不同的BEC方案的属性进行了研究。BEC中的链路服务水平通常不是恒定的，而是取决于多种因素。在一定条件下，新通道的信用额的总市场价值可以抵消其建设成本，私人公司的利润总是非负的。
Tradable credits have been recognized as a powerful instrument and are increasing used in many fields. This paper employs the tradable credits scheme on traffic mobility management and private provision of public transportation infrastructure through a novel kind of private financing of public road: build-equity-credit (BEC) scheme, hoping to achieve a triple win. Namely, the government can achieve its objectives (e.g. construction of the new road, desired traffic condition, certain vehicle emissions threshold) without its own capital, the private firm can receive its expected profit with less public’s resistance and the travelers can enjoy less congested traffic with a negligible cost. Moreover, many issues that occurred upon the termination of the traditional private financing (e.g. build-operate-transfer) scheme, such as severe congestion, explosion of travel demand and lack of management and maintenance, can be avoided in BEC. A general bi-level programming problem is formulated to model the determination of capacity of the new road and the tradable credits scheme in BEC scheme. The properties of several different BEC scenarios are investigated. Generally, the link service level in BEC is not constant but depends on multiple factors. Under some conditions, the total market value of the credits charged on the new link can offset its construction cost and the profit of the private firm can always be nonnegative.
