多年来，联邦公路管理局 (FHWA) 特纳费尔班克公路研究中心 (TFHRC) 一直在开展一项关于道路划定有效性的研究计划，以便为驾驶员在夜间在乡村双车道道路上通过弯道提供增强的指导。位于 TFHRC 的 FHWA 公路驾驶模拟器 (HDS) 在该研究项目中发挥着重要作用。然而，此类模拟器研究的结果必须通过在更自然的环境中进行现场测试来定期验证。对于本研究计划的第一系列研究，首先采用简化的道路场景进行了大量的模拟器实验，随后进行了适度的现场验证实验。后续实验代表了范式转变 采用更复杂的道路场景验证模拟器实验需要找到一条真实的乡村双车道道路，每个方向都有许多不同的曲线。首先找到这样一条自然道路，然后再对其进行模拟，这比设计一个模拟器场景，然后尝试找到一条在最重要的方面对应的自然道路要容易得多。通过首先进行现场实验，我们认识到了几个优点。这些优势大部分源自于首先处理真实情况的详细细节，然后识别相关方面并将其转移到模拟中。本文描述了其中一些优点并揭示了一些经验教训。
For several years the Federal Highway Administration (FHWA) Turner Fairbank Highway Research Center (TFHRC) has been conducting a research program on the effectiveness of roadway delineation for providing enhanced guidance to the driver negotiating curves on rural two-lane roads at night. The FHWA Highway Driving Simulator (HDS), located at the TFHRC, plays an important role in this research program. However, the results of such simulator research must be periodically validated by field testing in a more natural environment. For the first series of studies in this research program substantial simulator experiments were conducted first employing simplified roadway scenarios, and a modest field validation experiment was conducted later. Subsequent experiments represent a paradigm shift The validation of simulator experiments employing more complex roadway scenarios requires finding a real rural two-lane roadway with a number of different curves in each direction. It is much easier to find such a natural roadway first and then simulate it later, than it is to devise a simulator scenario and then try to find a natural roadway which corresponds in most significant ways. Several advantages were realized from conducting the field experiment first. Most of these advantages derive from working with the intimate details of the real situation first and then identifying and transferring relative aspects to the simulation. This paper describes some of these advantages and reveals some of the lessons learned.
