“…For advanced yield markings, the number of interactions where the driver did not yield was lower than that under the baseline condition; this result is consistent with the findings of Samuel et al (2013), who found that the number of drivers who yielded to pedestrians increased after the installation of this countermeasure. For the parking restrictions, the highest value (12%) was recorded; this result was unexpected.…”

“…This countermeasure is aimed at improving the yielding compliance; it should alert the driver further upstream of the crosswalk to the possible presence of pedestrians and prompt the driver to yield. Several studies have shown the effectiveness of this treatment because it increases the distance at which the driver yields to pedestrians, reduces the number of conflicts and increases the number of drivers that yield (Van Houten et al, 2001Samuel et al, 2013).…”

This countermeasure is aimed at improving the yielding compliance; it should alert the driver further upstream of the crosswalk to the possible presence of pedestrians and prompt the driver to yield .

SUMMARYThe driver's braking behavior while approaching zebra crossings under different safety measures (curb extensions, parking restrictions, and advance yield markings) and without treatment (baseline condition) was examined. The speed reduction time was the variable used to describe the driver's behavior. Forty-two drivers drove a driving simulator on an urban scenario in which the baseline condition and the safety measures were implemented. The speed reduction time was modeled with a parametric duration model to compare the effects on driver's braking behavior of vehicle dynamic variables and different countermeasures. The parametric accelerated failure time duration model with a Weibull distribution identified that the vehicle dynamic variables and only the countermeasure curb extensions affected, in a statistically significant way, the driver's speed reduction time in response to a pedestrian crossing.This result shows that the driver, because of the improved visibility of the pedestrian allowed by the curb extensions, was able to receive a clear information and better to adapt his approaching speed to yield to the pedestrian, avoiding abrupt maneuvers. This also means a reduction of likelihood of rear-end collision due to less aggressive braking.

“…Various strategies need to be identified through future research and employed to encourage drivers to yield more frequently, at all places, and specifically to male pedestrians. Previous research has indicated that advanced yield markings assist drivers scanning for pedestrians and reduce the conflicts between vehicles and pedestrians at marked crosswalks [23,34,35]. Other studies have found that pedestrians' gestures, smiles, stares, as well as improved infrastructure near pedestrian crossings, do improve driver yielding rates [22,24,[36][37][38].…”

“…In previous studies, low driver yielding rates were observed at non-signalized marked crosswalks at mid-blocks and near junctions [22][23][24]. The effect of pedestrians' gestures, smile, advance yield markings, and low-cost engineering improvements on driver yielding behavior at marked crosswalks was studied by Zhuang and Wu [22], Guéguen et al [23], Samuel et al [24], and Sandt et al [25] respectively. In case of low driver yielding rates, pedestrians must use their own judgment when they cross the road.…”

Road Users’ Behavior at Marked Crosswalks on Channelized Right-Turn Lanes at Intersections in the State of Qatar

et al. 2019

View full text Add to dashboard Cite

At non-signalized marked crosswalks, pedestrian priority is neither well-defined nor well acknowledged by drivers. This paper presents the findings of an investigation on both driver and pedestrian behavior at non-signalized marked crosswalks located on channelized right-turn lanes at intersections in the State of Qatar. Five crosswalks in Doha city were video recorded from discrete locations on a typical working day. The results from the data analysis of 1620 pedestrians’ behavior indicated that waiting behavior, gap acceptance, and crossing speed are complex phenomena and depend upon both pedestrians’ characteristics as well as their crossing characteristics. The drivers’ yielding behavior was mainly linked to pedestrians’ gender and adjacent land use. Low driver yielding rates indicated that significant improvements are required to enhance pedestrian safety. Among pedestrian attributes, gender had the most significant effect on crossing behavior followed by distractions, crossing in a group or alone, and dressing style. Findings of this research will be useful for planners when designing crosswalks at new intersections and during simulations of pedestrian and driver behavior at marked crosswalks on exclusive right-turn lanes. The results of this study will also be directly applicable to the Arabian Gulf countries as they exhibit similar conditions as the State of Qatar.
