“…Second, the greater number of vehicles with higher speeds will increase the crash risk and crash rates in the situation that the traffic volume mainly depended on segment width rather than the posted speed limits [ 33 , 34 ]. Third, compared with working by bicycle or foot, the crash rates increase with the journeys working by car, because the streets are more dangerous and crowded than pavement or bicycle lane during the commuting period [ 35 , 36 ].…”

Spatial autocorrelation and skewed distribution are the most frequent issues in crash rate modelling analysis. Previous studies commonly focus on the spatial autocorrelation between adjacent regions or the relationships between crash rate and potentially risky factors across different quantiles of crash rate distribution, but rarely both. To overcome the research gap, this study utilizes the spatial autoregressive quantile (SARQ) model to estimate how contributing factors influence the total and fatal-plus-injury crash rates and how modelling relationships change across the distribution of crash rates considering the effects of spatial autocorrelation. Three types of explanatory variables, i.e., demographic, traffic networks and volumes, and land-use patterns, were considered. Using data collected in New York City from 2017 to 2019, the results show that: (1) the SARQ model outperforms the traditional quantile regression model in prediction and fitting performance; (2) the effects of variables vary with the quantiles, mainly classifying three types: increasing, unchanged, and U-shaped; (3) at the high tail of crash rate distribution, the effects commonly have sudden increases/decrease. The findings are expected to provide strategies for reducing the crash rate and improving road traffic safety.

“…Those spaces should also be accessible and usable for everyone, reflecting the character of the area. In addition, to ensure the safety of pedestrians and bicyclists, working toward improving the infrastructure around the area is important (Asadi-Shekari et al, 2015a, 2015bMoeinaddini et al, 2015;Moeinaddini et al, 2014aMoeinaddini et al, , 2014b. One of the elements of Khisty (1994) method, which determines the qualitative level of service, is the security measure that distinguishes between pedestrian and vehicular movement safety.…”

“…The success of pedestrianization, or managing the change of an existing road over time, depends on certain principles. Previous studies show that to determine these principles; some quality criteria were required to be designed for pedestrian spaces (Alves & Ramalho, 2011;Asadi-Shekari, Moeinaddini, & Zaly Shah, 2015a, 2015bBlaga, 2013;Cengiz, 2011;Cengiz & Keçecioğlu Dağlı, 2017;Çol, 2004;Day, Boarnet, Alfonzo, & Forsyth, 2006;Ewing, Hajrasouliha, Neckerman, Purciel-Hill, & Greene, 2016;Isaacs, 2000;Khisty, 1994;Moeinaddini, Asadi-Shekari, Sultan, & Zaly Shah, 2015;Moeinaddini, Asadi-Shekari, & Zaly Shah, 2014a, 2014bSayyadi & Awasthi, 2012). Numerous studies were also conducted in Turkey for this purpose (Açık Etike & Erdönmez Dinçer, 2019;Alpak, Düzenli, & Yılmaz, 2018;Aytaş & Uzun, 2015;Cengiz, 2011;Cengiz & Keçecioğlu Dağlı, 2017;Çalışkan, 2011;Kızıloğlu & Polat, 2020;Özkaynak & Korkmaz, 2019;Resuloğlu, 2020;Saylan & Erdönmez Dinçer, 2017;Şenkaynak, 2010;Topçu, 2011;Uzgören & Erdönmez, 2017).…”

Pedestrian spaces are important public spaces that promote, support, and improve urban public life. Generally, these spaces are created by pedestrianizing existing streets, squares, plazas, and so forth as part of overall planning. Today, such an approach is considered an important urban strategy. One of the aims of pedestrianization is to clear certain areas from vehicular traffic in order to transform them into unconstrained and safe environments. Another purpose of pedestrianization is to improve mixed-use areas to ensure better performance of their functions. This study aims to determine the quality criteria that one should take into account while creating and managing pedestrian spaces and to measure the quality level of downtown Ankara's oldest and most used nine streets. For this purpose, a two-stage questionnaire, consisting of 22 questions, was conducted. The questions were collected from related literature and similar research. The data obtained in the first stage were evaluated by factor analysis, which is a quantitative method. The findings showed that the quality criteria were grouped into five main factors: design, maintenance, activities, accessibility, and safety. The data obtained in the second stage revealed the extent that the streets in the study area met these criteria. The study's findings revealed that the streets with the highest quality level were İzmir and Yüksel streets, and the street with the lowest quality level was Bayındır Street. The research determined the pedestrian space quality criteria in general and the strengths and weaknesses of the study area in particular. The results are a guide for planners, designers, managers, and policymakers who are engaged in developing existing spaces and creating new ones.

“…Infrastructure improvements are an important part of road safety enhancements that increase the walking and cycling safety and decrease fatalities [14]. Zegeer [15] and Davies [16] proposed that street facilities, such as adequate pedestrian crossing facilities, pedestrian refuges, curb build-outs, standard footways, tactile paving surfaces and traffic calming, could enhance pedestrian safety.…”
