“…Conventional pedestrian signals are the most commonly used type of signals worldwide. These systems in general show three messages: first, is a 'Steady Walk' sign (SW) or an animated green man walking-this indicates that pedestrians can cross the road; second, is the 'Flashing Don't Walk' sign (FDW) or a hand flashing-this indicates that pedestrians must not begin to cross the road, however pedestrians that have already commenced are ensured sufficient time; third, is a 'Steady Don't Walk' sign (SDW) or a steady handthis indicates that pedestrians must not be on the streets at all [1].…”

“…Another parameter to evaluate the PCT is the change in pedestrian behavior. In some studies, authors have concluded that there is a positive impact on pedestrian behaviour [1], [7], [10], [13], [15], [24]. Other studies however, found little evidence of the influence of countdown signals and suggested conducting further researches [18], [19], [25], [26].…”

The purpose of the research is to investigate the impact of pedestrian countdown timers on pedestrian behavior and examine if it enhances their compliance and safety. A treatment and control methodology was conducted at a total of seven intersections in Sharjah and Abu Dhabi. The pedestrian perception was gauged using a user preference survey that was distributed at the study intersections and online. Pedestrians are seen to have an overall positive perception of countdown timers. Pedestrian behavior was assessed via video recording. Video data was collected for a fixed duration in the morning and midday during a weekday. Various parameters were studied to measure pedestrian compliance and safety namelyproportion of violations, pedestrian-vehicle conflicts, successful crossings and pedestrians who ran out of time. Statistical analysis was carried out to analyze if the pedestrian proportion in a particular performance measure varied in a statistically significant manner between the two cases (with countdown timers and without countdown timers). A significant reduction in pedestrian noncompliance and a significant increase in the number of successful pedestrian crossings were observed. Overall, results show that pedestrian countdown timers are efficient in enhancing pedestrian safety and in aiding them to make better-informed decisions while crossing. However, to fully benefit from countdown timers, factors such as time allotted for the green and red phase as well as its location need to be considered. 

“…The analysis is based on the data collected through a revealed questionnaire survey (Lambrianidou, Basbas, & Politis, 2013;Lambrianidou, 2010). Research is focused on the compliance of pedestrians and the adaptation of their walking speed regarding the various time indications of the countdown timers.…”

“…Aigaiou street is a two directional road with one lane per direction and splitter island at the pedestrian crossing area. Adrianoupoleos street is a 4-lane single direction road, directed towards ''Macedonia'' airport (Lambrianidou et al, 2013). During a typical period, the cycle length of the traffic signal plan at the intersection is 90 s. The red phase for the pedestrians at the leg where the signal timer is installed lasts 68 s, as Fig.…”

“…Pedestrian violation can be considered as the inevitable outcome of the contradiction between external factors and human factors. Li [10] and Lambrianidou et al [11] gave various reports about pedestrians' behaviour influenced by time and distance. Guo et al [12,13] analysed the waiting behaviour during the street crossing by using the reliability theory and indicated the violation risk quantitatively with the increasing waiting time.…”

Pedestrian’s street-crossing behaviour has a significant effect on traffic performance and safety. The crossing behaviour is determined by human factors and environmental factors. Aiming at examining the pedestrian perceptions toward crossing facilities and preferences for crossing locations, an observational study of pedestrian crossing behaviour at urban street is conducted. The perceptions and preferences of pedestrians are collected using stated preference technique. A specific questionnaire is designed to conduct the stated preference survey. A multinomial logit model is proposed to describe the perceptions and preferences of pedestrians on crossing facilities and locations. The sensitivity analysis is performed to discuss the influence of various factors on crossing behaviour. Then the relationship between crossing locations and crossing distances is analyzed by a new proposed method. With the theoretical analysis, the engineering solutions considering pedestrian behaviour are suggested. The results are helpful to design human-centered crossing facilities in urban traffic.
