“…is section (especially the longitudinal slope was about 4%) was generally the tunnel entrance or nearly the entrance. Typically, vehicle speed increases in the long downhill section of tunnel entrance, and the drivers may need to step on the brakes [21] and stare at the dashboard to avoid speeding and rear-end collision. Meanwhile, for the uphill section, the drivers need to step on the throttle and gaze at the dashboard and rearview mirror because of the low speed in uphill section.…”

This study aims to investigate the impact of the urban undersea tunnel longitudinal slope on the visual characteristics of drivers. 20 drivers were enrolled to conduct the real vehicle test of the urban undersea tunnel. First, the data of average fixation time and visual lobe were collected by an eye tracker. The differential significance was tested using the one-way repeated measures analysis of variance (ANOVA). Then, the difference between the up-and-down slope (direction) factor and the longitudinal slope (percent) factor on the two indexes were analyzed using the two-way repeated measures ANOVA. Second, by constructing a Lorentz model, the impact of the longitudinal slope on the average fixation time and the visual lobe were analyzed. Besides, a three-dimensional model of the longitudinal slope, average fixation time, and visual lobe was quantified. The results showed that the average fixation time and visual lobe under different longitudinal slopes markedly differed when driving on the uphill and downhill sections. The average fixation time and visual lobe under two factors were markedly different. Moreover, with an increase in the longitudinal slope, the average fixation time exhibited a trend of increasing first then decreasing; the visual lobe exhibited a trend of decreasing first and then increasing. The average fixation time reached the minimum and maximum value when the slope was 2.15% and 4.0%, whereas the visual lobe reached the maximum and minimum value when the slope was 2.88% and 4.0%. Overall, the longitudinal slope exerted a great impact on the visual load of the driver.

“…A questionnaire survey was conducted among the elderly aged 65 years and above to explore key issues with the driving experiences of older compared with younger drivers (Karali et al, 2017). Deng et al (2019) studied the correlation between pedal operations (foot maneuvers) and drivers' workload by using the mechanism of workload on sloped segments of mountainous roads. The study performed naturalistic driving tests on two-lane mountainous roads in China.…”

“…The research targeted young drivers are in aged between 18 to 27 years old (Consiglio et al, 2003;Groeger & Murphy, 2020). Meanwhile, most of the other studies recruited participants aged between 22 to 65 years old (Deng et al, 2019;Jammes et al, 2017b;McGehee et al, 2016;Mcgehee et al, 2000;Tran et al, 2012;Wu et al, 2014). All studies performed required the participants to have a certified driving license from the authority.…”

“…The recorded anthropometric data is to determine whether the driver's sex or anthropometry are related to driver-vehicle fit. Deng et al (2019) also conducted a naturalistic driving study to observe the correlation between pedal operations (foot maneuvers) and drivers' workload and the mechanism of workload on sloped segments of mountainous roads. The naturalistic driving test is performed at three mountain road segments with two-lane mountainous roads located in Fengjie County, Wuxi County, and Yunyang County in Chongqing, China.…”

The movement of the driver’s foot from one pedal to another is a blind positioning movement. Variability of driver’s foot movement might lead to pedal error or pedal misapplication. In this paper, we reviewed the research focus in the pedal error study, who are the participants involved in the study, what kind of approach or method used to perform the pedal error study, how is the test setup, test condition, and flow of the study, and what are the factors influencing the pedal error accidents. The review searched relevant articles based on five keywords: pedal errors, pedal misapplication, sudden unintended acceleration (SUA), automotive foot pedals, and sudden acceleration accidents. Based on the review, the research focus is focusing on the factors causing the pedal error, understanding the fundamental principles of pedal misapplications, and characteristics of pedal errors among older drivers. The pedal error study has been conducted either using the naturalistic driving, driving simulation, or survey. The pedal error among ASEAN drivers is essential since there is no study related to this topic has been conducted in any ASEAN countries yet.

“…Driving behaviour studies have shown that driver characteristics, such as gender [11,12], experience [13][14][15], and driving style [16], are strongly associated with driving behaviour and traffic safety [14,17]. Studies have shown that driving speed and deceleration directly affect driving safety [18,19], and the driver's pedal operation behaviour is closely related to and influenced by the driver's physiology and psychology [20]. Moreover, road geometry parameters affect drivers to behave differently [21,22]: Even when exposed to the same traffic facilities and environments, different drivers exhibit different behaviours based on their personal characteristics.…”

Exploring longitudinal driving behaviour on a freeway deceleration lane using field operational test data

The deceleration lane isbefore numbers to minus signs. a critical part of the freeway, enabling vehicles to exit the expressway safely and in an orderly fashion. However, drivers are human and thus make subjective decisions while driving; as such, each driver may approach and traverse the deceleration lane differently. This variance, which can cause major traffic disruptions and collisions, can be observed -and even mitigated, as proposed herein -based on a driver's particular characteristics. To study the variances in the longitudinal vehicle positions and microscopic operating characteristics of different drivers on a freeway exit area, a field operational test involving 46 subjects was carried out to collect data on driver characteristics, vehicle motion postures, micro-driving operations, and road geometric elements. The 46 participants were observed based on experience and gender, and the mathematical statistical method was used to analyse driving differences in the deceleration lane. The results show that (1) the vehicle motion state can be divided into four operational stages on the deceleration lane: the pre-deceleration process, the dynamic adjustment process, the first braking process, and the second braking process; (2) drivers generally adopted deceleration behaviour rather than maintain uniform speed when driving in the taper; (3) about 50% of drivers braked after entering the deceleration lane; (4) male drivers and skilled drivers were more inclined to drive at a higher speed on the deceleration lane, and female drivers showed a sharp increase in braking frequency once they travelled 110-150 m downstream of the taper starting point. The results of this study provide data and insights for deceleration lane design, traffic management, and driver training.How to cite this article: Lyu, N., et al.: Exploring longitudinal driving behaviour on a freeway deceleration lane using field operational test data.
