Current approaches in bridge valuation mostly focus on engineering construction costs while neglecting other values generated by the bridge's functionality and utilization, along with other indirect economic values of a bridge. Such limitations prevent public agencies from capturing the true asset value of their bridges to make informed management decisions. The objective of this paper is to develop a comprehensive bridge asset valuation methodology that is based on the utility theory concept to better represent the asset value of a bridge. Various factors featuring the bridge asset value are characterized and considered in the model including physical condition, safety, mobility, average annual daily traffic (AADT), direct time savings, and so on. These factors are categorized into economic value and utility-based value and quantified with specific performance measures. The applicability of the proposed methodology is demonstrated through a case study using five real-world bridges in Austin, Texas. The results show that the integrated, comprehensive model is able to effectively evaluate the overall asset value of a bridge. Finally, the paper discusses how public agencies can take advantage of the evaluation results to better understand bridge asset value and make more insightful decisions in bridge management practice.

当前桥梁评估的方法主要集中在工程建设成本上，而忽略了桥梁功能和利用所产生的其他价值，以及桥梁的其他间接经济价值。这样的局限性阻止了公共机构获取其桥梁的真实资产价值来做出明智的管理决策。本文的目的是开发一种基于效用理论概念的综合桥梁资产评估方法，以更好地表示桥梁资产价值。在模型中表征并考虑了具有桥梁资产价值的各种因素，包括身体状况，安全性，机动性，年均日流量（AADT），直接节省的时间等。这些因素分为经济价值和基于效用的价值，并通过特定的绩效指标进行量化。通过使用德克萨斯州奥斯丁市的五个真实世界桥梁的案例研究，证明了所提出方法的适用性。结果表明，集成的，综合的模型能够有效地评估桥梁的整体资产价值。最后，本文讨论了公共机构如何利用评估结果来更好地理解桥梁资产价值，并在桥梁管理实践中做出更具洞察力的决策。综合模型能够有效评估桥梁的整体资产价值。最后，本文讨论了公共机构如何利用评估结果来更好地理解桥梁资产价值，并在桥梁管理实践中做出更具洞察力的决策。综合模型能够有效评估桥梁的整体资产价值。最后，本文讨论了公共机构如何利用评估结果来更好地理解桥梁资产价值，并在桥梁管理实践中做出更具洞察力的决策。
