Abstract

In Thailand, traffic rule violations and crashes involving motorcycles have increased with the rising number of new motorcycle registrations. A common issue in Thai traffic is motorcyclists riding in the wrong direction. This research proposes a two-way motorcycle lane design to address the wrong-way riding behavior of motorcyclists in Thailand. The design aims to segregate motorcycles from larger vehicles, improving safety. Traffic simulation software was used to model a selected road section in Thailand, incorporating the wrong-way riding behavior. After calibration, the proposed two-way motorcycle lane design was simulated within the same network. Traffic conflicts in each network were analyzed using the Surrogate Safety Assessment Model (SSAM). The safety of the proposed design was compared to the existing conditions and found to result in fewer severe conflicts, especially when priority is given to motorcycles at access points. The study also identified the most suitable width for the two-way motorcycle lane based on the safety assessment. For the motorcycle lane priority option, a 3-m lane width was found to be the safest, while for the option with priority given to vehicles on access roads, a 3.5-m lane width was identified as the safest design.

评估双向摩托车道以减少交通冲突及其严重程度：以泰国Phaholyothin道路为例

在泰国，随着新摩托车登记数量的增加，涉及摩托车的交通规则违规和撞车事故也在增加。泰国交通的一个常见问题是摩托车手逆行。本研究提出了一种双向摩托车车道设计，以解决泰国摩托车手的错误骑行行为。该设计旨在将摩托车与大型车辆隔离开来，以提高安全性。交通模拟软件被用来模拟泰国选定的路段，包括错误的骑行行为。校正后，在同一网络内对所提出的摩托车双向车道设计进行了仿真。采用代理安全评估模型（SSAM）对各网络中的流量冲突进行分析。将拟议设计的安全性与现有条件进行比较，发现导致较少的严重冲突，特别是当在接入点优先考虑摩托车时。在安全评价的基础上，确定了摩托车双向车道的最适宜宽度。对于摩托车车道优先方案，3 m车道宽度是最安全的，而对于通道上的车辆优先方案，3.5 m车道宽度是最安全的设计。

期刊介绍： First published in 1977 as an international journal sponsored by the International Association of Traffic and Safety Sciences, IATSS Research has contributed to the dissemination of interdisciplinary wisdom on ideal mobility, particularly in Asia. IATSS Research is an international refereed journal providing a platform for the exchange of scientific findings on transportation and safety across a wide range of academic fields, with particular emphasis on the links between scientific findings and practice in society and cultural contexts. IATSS Research welcomes submission of original research articles and reviews that satisfy the following conditions: 1.Relevant to transportation and safety, and the multiple impacts of transportation systems on security, human health, and the environment. 2.Contains important policy and practical implications based on scientific evidence in the applicable academic field. In addition to welcoming general submissions, IATSS Research occasionally plans and publishes special feature sections and special issues composed of invited articles addressing specific topics.
