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.

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.
