“…Roadway surface was cast in a binary way-Surface = 0 if dry and 1 if snowy, icy, slushy, wet, debris, or muddy, representing all the remaining, compromised surface conditions. Results suggest that adverse surface conditions contributed to lower severity levels, which is consistent with previous findings, see, e.g., (17). Intuitively, drivers tend to slow down under bad weather or surface conditions, and lower speed often prevents serious crash injuries.…”

Little is known about the safety of tourist drivers in the United States. Most domestic studies focused on traffic deaths/injuries of U.S. citizens traveling abroad, citing chief factors such as left-driving, lack of seat belt use, and alcohol consumptions. For states where there are a number of tourism attractions and roadways to reach them, it is of interest to investigate whether traffic safety is an issue for tourist drivers. To that end, this research work investigated the contributing factors for crash severity and crash likelihood of park-visiting drivers in or near three national parks in rural areas. The driver-level data from the Rocky Mountain National Park (ROMO) and the Sequoia and Kings Canyon National Park (SEKI) revealed risk factors for crash severity including age, geometry, seat belt usage, among others. To anticipate crash likelihood of visiting drivers, the second data set offered a more microscopic view at the road level. It contained road geometry, traffic volume, environment, and crash counts aggregated at the segment level along a 57.8-mile tourist route of US Highway 89 (a primary route to the north gate of Yellowstone National Park). Crash risk factors (e.g., geometry and traffic intensity) affected local and nonlocal (tourist) drivers in different ways. Further exploration of crash trends in specific parks would be valuable to understand the overall trends and contributors to crashes in tourism areas and determine the effective improvement measures.

“…Serious pavement failure in the form of cracks, potholes, deformations, pushings and ruttings were observed on major highways (Aghamelu and Okogbue ). Studies have shown that poor pavement condition increases severity of crashes on high speed roads (Lee, Nam and Abdel‐Aty ; Li et al . ).…”

This study examined the spatial distribution of road traffic crashes, mortality and morbidity in Nigeria for the period 2007–2017. The influence of exposure, road network and socio‐demographic characteristics on fatalities and injuries was analysed. Data were obtained from Federal Road Safety Corps and Annual Abstract of Statistics. Spatial statistical techniques were employed to determine the pattern of crashes, mortality and morbidity. Ordinary least squares and geographically weighted regression models were used to identify significant variables. Crashes and mortality declined by 47.9 per cent and 46.3 per cent respectively, while morbidity increased by 78.6 per cent. Crashes, mortality and morbidity were significantly clustered and high in Niger, Kaduna, FCT, Kogi and Nassarawa States. FCT recorded the highest crashes and injured persons, while Kaduna recorded the highest fatalities. Variables that significantly influenced spatial variation of mortality and morbidity were length of asphaltic concrete, surfaced dressed and earth roads, unemployment and population density. This study shows that type of road is a major factor that contributes to road crash mortality and morbidity. Crash countermeasures such as implementation of safety standards during road construction, speed reduction strategies and enforcement of seat belt use and child restraint should be implemented.

“…The paper by Lee et al (2015) focuses on the development of the relationship between poor pavement conditions and crash severity levels using a series of Bayesian ordered logistic models for low/medium/high speed roads and single/multiple collision cases. Solatifar et al (2017) presents a simple method to determine dynamic modulus master curve of asphalt layers by conducting Falling Weight Deflectometer (FWD) for use in mechanisticempirical rehabilitation.…”

In Lithuania, the efforts are made to ensure the conditions of safe, comfortable and fast passenger and freight transportation on Lithuanian roads, satisfying geometric characteristics of their particular categories and the specified requirements to their pavement. The considered characteristics of pavement include its roughness, strength and the admissible rut depth and destruction level. Rest and Service Areas (RSAs) are usually set up at the roadside. The paper presents a description of the conditions specified for the movement of motor vehicles on the major Lithuanian roads in the seasons of warm weather and a Classification Model (CM) of the required conditions. It also provides the results of the evaluation of actual Travel Conditions (TCs) on the main Lithuanian roads by using the developed model. The obtained results show that in 2016 on the considered highways were good and very good, except for road A9, where the TCs were satisfactory. It is demonstrated that the distances between RSAs comply with the recommended distances. It is also shown that roughness of pavement and strength of the Structure of the Pavement (SP) depend on the destruction level of pavement. The values of such pavement parameters as roughness, rut depth and destruction level, which should not be exceeded because they help to ensure either comfortable or good TCs on Lithuanian highways, are given. The suggested model of road TCs can be used for determining the quality of TCs on highways.
