“…In particular, workers per residents (WKGD) is associated with C car , C truck , C seg , C peaknight and C day . These results confirm earlier research by Lovegrove et al [15] and Kim et al [39,94]. The difference between C peaknight and C peakday is related to the different activities carried out during the hours of the day.…”

This paper presents macro-level safety performance functions and aims to provide empirical tools for planners and engineers to conduct proactive analyses, promote more sustainable development patterns, and reduce road crashes. In the past decade, several studies have been conducted for crash modeling at a macro-level, yet in Italy, macro-level safety performance functions have neither been calibrated nor used, until now. Therefore, for Italy to be able to fully benefit from applying these models, it is necessary to calibrate the models to local conditions. Generalized linear modelling techniques were used to fit the models, and a negative binomial distribution error structure was assumed. The study used a sample of 15,254 crashes which occurred in the period of 2009–2011 in Naples, Italy. Four traffic analysis zones (TAZ) levels were used, as one of the aims of this paper is to check the extent to which these zoning levels help in addressing the issue. The models were developed by the stepwise forward procedure using explanatory Socio-Demographic (S-D), Transportation Demand Management (TDM), and Exposure variables. The most significant variables were: children and young people placed in re-education projects, population, population aged 65 and above, population aged 25 to 44, male population, total vehicle kilometers traveled, average congestion level, average speed, number of trips originating in the TAZ, number of trips ending in the TAZ, number of total trips and, number of bus stops served per hour. An important result of the study is that children and young people placed in re-education projects negatively affects the frequency of crashes, i.e., it has a positive safety effect. This demonstrates the effectiveness of education projects, especially on children from disadvantaged neighbourhoods.

“…Hbus is a proxy for pedestrian traffic, so the positive sign indicates a growing correlation with crashes. The association between increased collisions and increased bus stops (BS) is consistent with researches of Kim et al [39,94], Wei et al [88] and Rhee et al [98]. A larger number of subway stations were found to increase traffic crashes.…”

“…As the fundamental landscape component that shapes diversified regional forms and functions, the roles of individual land use classes, including commercial (Kim, Pant, & Yamashita, 2010), industrial (Priyantha Wedagama, Bird, & Metcalfe, 2006), residential (Kim & Yamashita, 2002), educational (Sebos, Progiou, Symeonidis, & Ziomas, 2010), and official land uses (Narayanamoorthy, Paleti, & Bhat, 2013), in explaining SCs have been continually investigated. Several recent studies have also emphasized the effects of land use structures on SCs.…”

“…Compared with residential areas, the likelihood of crashes occurring in commercial areas [ [16] and OUYANG and BEJLERI [17], we find that the presence of additional overpasses may account for the crash frequency reductions in commercial and mixed-land areas of Hong Kong. As shown in Fig.…”

Although extensive analyses of road segments and intersections located in urban road networks have examined the role of many factors that contribute to the frequency and severity of crashes, the explicit relationship between street pattern characteristics and traffic safety remains underexplored. Based on a zone-based Hong Kong database, the Space Syntax was used to quantify the topological characteristics of street patterns and investigate the role of street patterns and zone-related factors in zone-based traffic safety analysis. A joint probability model was adopted to analyze crash frequency and severity in an integrated modeling framework and the maximum likelihood estimation method was used to estimate the parameters. In addition to the characteristics of street patterns, speed, road geometry, land-use patterns, and temporal factors were considered. The vehicle hours was also included as an exposure proxy in the model to make crash frequency predictions. The results indicate that the joint probability model can reveal the relationship between zone-based traffic safety and various other factors, and that street pattern characteristics play an important role in crash frequency prediction.
