Abstract

Objective

The driver’s inability to fully absorb and react to operational cues while driving is like boiling a frog in warm water. With intermittent, low-volume information, drivers can underreact by ignoring these minor but continuous changes. This paper aims to provide an opportunity to test the effects of intermittently occurring low-volume information on drivers.

Methods

A real vehicle test with naturalistic driving was used to collect driving speed data from 40 drivers on a highway tunnel section in Chongqing, China, where nine tunnels are located. Drivers were classified into three categories according to the degree of compliance of their driving speed with the speed limit required by traffic signs, and drivers were analyzed in terms of their sensitivity to traffic signs and their reaction to driving maneuvers.

Results

Conservative drivers are the most absorbent of low-volume intermittent information, and the cumulative effect of the frog effect does not exceed 2.00 km; eager drivers tend to ignore this information, and the cumulative effect of the frog effect reaches 2.91 km; and the general type of driver is in the middle of these two types of drivers, and the frog effect gradually penetrates the driving speed in a weakly increasing manner, up to a maximum of 9.8 km.

Conclusion

At the beginning of a journey, drivers are most sensitive to traffic signs, and low-volume intermittent information can also play a role in guiding driving operations effectively at this time. However, as the driving distance increases, the effect of the frog effect on different types of drivers gradually increases, even exceeding the effect caused by the black-and-white hole effect, especially when driving in tunnel groups. Considering the driving characteristics of different types of drivers to improve the deployment of low-volume intermittent information and reduce the distance of the frog effect can effectively improve driving safety.

对山区高速公路隧道内司机所受青蛙效应的综合评估--低流量间歇性信息的影响。

目标：驾驶员在驾驶过程中无法充分吸收操作提示并作出反应，就好比温水煮青蛙。对于间歇性的低量信息，驾驶员可能会忽略这些微小但持续的变化，从而反应不足。本文旨在提供一个机会，测试间歇性出现的低量信息对驾驶员的影响：方法：通过自然驾驶实车测试，收集了 40 名驾驶员在中国重庆高速公路隧道路段的驾驶速度数据，该路段共有 9 座隧道。根据驾驶速度与交通标志限速要求的符合程度，将驾驶者分为三类，并从驾驶者对交通标志的敏感性和对驾驶操作的反应两方面对驾驶者进行分析：结果：保守型驾驶员对低流量间歇性信息的吸收能力最强，蛙式效应的累积效应不超过 2.00 km；急切型驾驶员倾向于忽略这些信息，蛙式效应的累积效应达到 2.91 km；而一般型驾驶员处于这两类驾驶员的中间，蛙式效应以弱递增的方式逐渐渗透到驾驶速度中，最大可达 9.8 km：结论：在旅程开始时，驾驶员对交通标志最为敏感，低流量间歇性信息在此时也能起到有效指导驾驶操作的作用。但随着行驶距离的增加，蛙式效应对不同类型驾驶员的影响逐渐增大，甚至超过了黑白洞效应所造成的影响，尤其是在隧道群中行驶时。考虑不同类型驾驶员的驾驶特点，改进低流量间歇信息的部署，减少蛙式效应的距离，可以有效提高驾驶安全性。

期刊介绍： The purpose of Traffic Injury Prevention is to bridge the disciplines of medicine, engineering, public health and traffic safety in order to foster the science of traffic injury prevention. The archival journal focuses on research, interventions and evaluations within the areas of traffic safety, crash causation, injury prevention and treatment. General topics within the journal''s scope are driver behavior, road infrastructure, emerging crash avoidance technologies, crash and injury epidemiology, alcohol and drugs, impact injury biomechanics, vehicle crashworthiness, occupant restraints, pedestrian safety, evaluation of interventions, economic consequences and emergency and clinical care with specific application to traffic injury prevention. The journal includes full length papers, review articles, case studies, brief technical notes and commentaries.
