Abstract

Driving comfort assessment is a prerequisite to improve the journey experience for the drivers as well as the passengers. In this work, we proposed an advanced approach for the measurement of driving comfort in real-time. Different types of environmental features are considered along with the traditionally used Comfort Index (CI), and an Environment-specific Comfort Index (EsCI) is proposed. EsCI is also inversely proportional to the drivers' comfort level, just like CI. We also developed an android application named QDCL (Quantification of Driver Comfort Level) for overall data collection and computation of EsCI from the same. A series of driving experiments at different times of the day and different traffic conditions have been performed in Indian urban road scenarios to assess the performance of QDCL and the relevance of EsCI. We extended the work by studying the effects of different external stimuli on the computed driving comfort level. The performance of EsCI is observed to outperform the traditionally used CI (Comfort Index) in terms of accuracy for the quantification of overall driving comfort.

驱动舒适性测量的新范式：环境特定舒适性指数及其在印度环境中的实时应用

驾驶舒适性评估是提高驾驶员和乘客出行体验的前提。在这项工作中，我们提出了一种先进的实时驾驶舒适性测量方法。考虑了不同类型的环境特征以及传统使用的舒适度指数（CI），并提出了环境特异性舒适度指数（EsCI）。与CI一样，EsCI也与驾驶员的舒适度成反比。我们还开发了一个名为QDCL （Quantification of Driver Comfort Level）的android应用程序，用于收集驾驶员舒适度的整体数据并计算驾驶员舒适度。在印度城市道路场景中，在一天中不同时间和不同交通条件下进行了一系列驾驶实验，以评估QDCL的性能和EsCI的相关性。我们通过研究不同外部刺激对计算的驾驶舒适度的影响来扩展工作。EsCI的性能被观察到优于传统使用的CI（舒适指数）在准确性量化整体驾驶舒适性。

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.
