“…To do this, stepwise multiple linear regression analysis was performed using data collected from various types of crossings in the Japanese city of Sapporo. [8] Study provides a methodology for assessing crossing safety at signalized intersections when there is mixed traffic, utilizing Surrogate Safety Measures (SSM). The results show that the suggested PET ranges and model are appropriate for mixed traffic circumstances in India.…”

The main objective of this research is to identify the variables that affect the level of service (Los) of pedestrians at intersections both (signalized and unsignalized) in shivamogga city. Based on the experiences of the pedestrians at the individual in intersections. A walker’s questionnaire survey was done to gather level of service of pedestrians in terms of protection, comfort, and convenience for every crossing at signalized & unsignalized intersections. Additionally, a video graphic method was employed to scan each crosswalk at the chosen three signalized and two unsignalized intersections. Pedestrian crossing time, pedestrian waiting time, pedestrian holding area, roadway width, and crosswalk surface condition were the key variables taken into account for the construction of the model. For each crossing, a considerable number of pedestrian ratings were collected, these ratings were used as the dependent variables in the analysis. In order to estimate the pedestrian level of service for each intersection's crosswalk, a stepwise multiple linear regression analysis utilizing SPSS software is used to construct a pedestrian Los model.

Signalized intersections and roundabouts are two types of intersections with different systems. The roundabout at Basecamp intersection, in exchange for signalized intersection in the past, is a new thing in that area. This study aims to determine the opinions of basecamp intersection users who used signalized intersections before switching to the roundabout. The effectiveness of using roundabouts compared to the signalized intersection is measured from users' experience of the basecamp intersection as a benchmark. The user-experience-based questionnaire is the primary method to obtain the user's data which is presented in the form of an average scale of performance for each parameter on the radar graph. In total, roundabout outperforms signalized intersection slightly. However, there are significant gaps in performance on driver distraction-free and traffic flow where roundabouts lead. On the other side, signalized intersections significantly dominated the performance of pedestrians' safety. Meanwhile, there are slight differences in drivers' safety and a respectable gap in drivers' ability where signalized intersections lead.

“…The evaluation results indicated that the developed fuzzy C-means method can produce more accurate results and efficient threshold values for the pedestrian level of service score. Similarly, warrants for pedestrian crossing facilities in midblock segments were recommended through pedestrian-vehicle conflict analysis and videographic surveys, which enhance the design of efficient crossing facilities that address both pedestrian and vehicular traffic flow [10,11]. Ke et al developed a comprehensive index around environmental, economic, social, and transportation efficiency to deal with traffic-oriented development problems combined with the FAHP.…”

Increasingly, cities worldwide are striving for green travel and slow traffic, and vigorously developing people-oriented urban pedestrian traffic with sustainability has become a fixture in recent discourse. This paper comprehensively considers the sidewalk’s facilities environment and the status of pedestrian traffic flow; divides the urban pedestrian road system (UPRS) into five subsystems around the underpass, overpass, crosswalk, sidewalk, and road crosswalk; and introduces the basic structure as well as the function of each system. Then, the indicators are classified into two types of crosswalk facilities and sidewalk facilities, and a comprehensive pedestrian road indicator system with the combination of subjective and objective is established. Consequently, the integration of the fuzzy AHP and DEA-based symmetrical technique for the subjective evaluation indicator combined with pedestrian traffic characteristics is developed. A nine-step semantics scale of relative importance was used so that the symmetry of the response of pedestrian satisfaction was maintained. Fuzzy evaluation based on AHP is further modeled, and the DEA is employed to achieve an overall evaluation of the quality of service (QoS) for UPRS. The applicability of the established evaluation system is finally verified through a real case study in Harbin, China. The serviceability assessment method in this paper provides a new idea for planners to conduct sustainability evaluation for UPRS in future urban renewal development.
