“…Out of two, one deals with the empirical methodology based on the intersection geometry and the other depends purely on the gap acceptance process. Many researchers used a simulation approach to study the roundabout capacity [12][13][14][15][16]. The Indian standard document, referred to as Indian Roads Congress (IRC) [17], gives the formula for estimation of the entry capacity of the roundabout.…”

Models developed in Highway Capacity Manual (HCM) are not suitable to cater to the effects of mixed traffic conditions and hence, its use is unjustifiable. This research investigates such a challenging problem as the effect of undesignated pedestrian crossings on the entry capacity of roundabouts. For the present study, field survey data were collected using video cameras from three roundabouts such that the base section (roundabout without pedestrian influence) and non-base sections (with pedestrian influence), both scenarios, were captured. A modified HCM equation was developed to estimate entry capacity and further, the reduction in capacity with respect to pedestrian volume is determined. Lastly, a relationship was developed to check the effect of pedestrian crossflow on the entry capacity. The relation shows that capacity reduced to 1841 Passenger Car Unit (PCU/h) when the pedestrian flow increased to 288 pedestrians/hour.

Featured Application: The current article proposes traffic modelling in a roundabout on the basis of cellular automata. It also considers roundabout traffic reorganisation in order to increase roundabout capacity. The article also presents an analysis on the impacts of pedestrian traffic and on distances between vehicles. An analysis focussing on multi-lane roundabouts is also provided. Abstract:The current article presents a roundabout traffic model based on cellular automata for computer simulation. The model takes into account various sizes of roundabouts, as well as various types and maximum speeds of vehicles. A realistic vehicle braking phase is presented which is adjusted to the kind of vehicle and weather conditions. It also analyses roundabout traffic options including where the various rules for entering and exiting a roundabout apply. Traffic rules are contained in respective traffic scenarios. The simulation results indicate that there is significant scope for roundabout traffic reorganisation, with a mind to increasing roundabout capacity.

“…Koh et al (2014) modeled the probability of violating using the various personal characteristics, situational and environment conditions with logistic regression. Moreover, pedestrian–vehicle interactions at a roundabout system were analyzed in the work of Echab et al (2016). In Shanghai (Ni et al, 2017), 1286 pedestrians were asked to rate their safety perception from 1 to 5.…”

This study sheds light on pedestrian and driver's behavior towards crossing in Kuwait. It examined the effect of different factors on pedestrian and vehicle violations at 10 locations in Kuwait including signalized, nonsignalized intersections, locations with/without pedestrian's bridge, and locations with/without pedestrian crossing signals. Four types of pedestrian's violations were observed; crossing outside the marked crossway, not obeying traffic signal, distracted crossing (eating, drinking, or using a smartphone while crossing), and not using pedestrian's bridge. For vehicle violations, two types were observed; not yielding to pedestrians and stopping over the marked crossway. The pedestrian and vehicle violations observed are considered as “violations” according to the existing Highway Code in Kuwait. A total of 24,393 pedestrian crossing violations were recorded over 40 days. Pedestrian violations were analyzed using a multinomial logit model while vehicle violations were analyzed by frequencies analysis. Video data were used for validation applying a trajectory‐based approach showing a high accuracy level of 98.85%. The results showed that all the studied factors; time of observation including weekdays and weekends, and peak and off‐peak hours, location of observation, demographic characteristics including pedestrian gender, and age, and site properties (with/without pedestrian's bridge and with/without pedestrian crossing signal) were significant and had a strong relationship with the type of violations. The results also indices the importance of providing pedestrian's bridge in locations with a high number of violations.
