Understanding travelers' acceptance of Advanced Traveler Information Systems (ATIS) is crucial to the implementation of Intelligent Transportation Systems (ITS) capable of mitigating traffic congestion and improving network performance. This paper adopted an extended Technology Acceptance Model (TAM) to predict and explain road users' intention to use Variable Message Sign (VMS) information. In addition to the traditional parsimonious TAM constructs (perceived usefulness, perceived ease of use and behavioral intention), the model examined the effects of attitude towards route diversion, familiarity with road network and information quality on road users' acceptance of VMS. 762 drivers were interviewed and the obtained data were processed using Structural Equation Modeling. The results showed that travelers' attitude towards route diversion had a positive effect on perceived usefulness and intention to use VMS. Information quality had a positive direct effect on perceived usefulness, perceived ease of use and attitude towards route diversion. Familiarity with the network had a positive effect on attitude towards route diversion and a negative effect on the perceived usefulness of VMS information. Perceived ease of use significantly and positively affected perceived usefulness and intention to use VMS. Perceived usefulness also had a positive effect on intention. Several academic and practical implications were also discussed.
理解旅行者对高级出行者信息系统（ATIS）的接受程度对于实施智能交通系统（ITS）至关重要，这些系统能够缓解交通拥堵并提高网络性能。本文采用扩展的技术接受模型（TAM）来预测和解释道路使用者使用可变信息标志（VMS）信息的意图。除了传统的简约 TAM 结构（感知有用性、感知易用性和行为意图）外，该模型还考察了对路线改道的态度、对路网的熟悉程度和信息质量对道路使用者接受 VMS 的影响。对 762 名驾驶员进行了访谈，并使用结构方程模型处理了获得的数据。结果表明，旅行者对路线改道的态度对感知有用性和使用 VMS 的意图有积极影响。信息质量对感知有用性、感知易用性和对路线改道的态度有积极的直接影响。对网络的熟悉程度对路线改道的态度有积极影响，对 VMS 信息的感知有用性有负面影响。感知易用性显著且积极地影响了感知有用性和使用 VMS 的意图。感知有用性也对意图有积极影响。还讨论了一些学术和实际意义。
