SGER - 3-D Sight Distance Computation

摘要提案0129096大卫J.洛弗尔马里兰州大学公园SGER- 3-D视距计算2001年8月1日PI提出了探索性研究，旨在解决一个永久的交通设计问题-自动和有效的测量三维公路线形的可用视距。这本身就是一个重要的问题，因为由于劳动力的减少，对高速公路设计可行性测试和评估的自动化需求日益增长。自动化被问题的计算复杂性所阻碍。如果研究成功，将为视距问题提供一种更有效的算法，提高公路设计的评价、选择和安全性。这将对交通界产生重大影响，包括大学、公共和私人机构，如道路建设和维护、交通运营、安全等。此外，解决该问题所需的数学框架可以支持许多其他调查，如清晰的区域宽度，超车道分界线等。

ABSTRACTProposal 0129096David J. LovellUniversity of Maryland College ParkSGER - 3-D Sight Distance ComputationAugust 1, 2001The PI proposes exploratory research aimed at solving a perpetual transportation design problem - the automated and efficient measurement of available sight distance for three-dimensional highway alignments. This is an important problem in its own right because of the growing need to automate design feasibility test and evaluation for highways due to workforce reductions. Automation is thwarted by the computational complexity of the problems. If successful, research the results will be a more efficient algorithmic to the sight distance problem and improved highway design evaluation, selection and safety. This will have a significant impact on the transportation community, including universities, public and private agencies such as roadway construction and maintenance, traffic operations, safety. Additionally the mathematical framework required to solve the problem can support a number of other investigations, such as clear zone widths, passing lane demarcations, etc.
