Abstract:
... A number of traffic crash databases at present contain the precise positions and dates of these events. This feature allows for detailed spatiotemporal analysis of traffic crash patterns.We applied a clustering method for identification of traffic crash hotspots to the rural parts of primary roads in the Czech road network (3,933 km) where 55,296 traffic crashes occurred over 2010 – 2018. The data ...

Abstract:
... Increasing and projected shortages in non-renewable energy sources have directed attention toward the potential for using regenerated energy from road traffic. There are currently three primary techniques for harvesting energy from roadways—piezoelectricity, thermoelectricity and photoelectricity—although, to date very few studies have focussed on the potential for integrating two or more of these ...

Abstract:
... In this study, a method for the determination of tire and road wear particle (TRWP) contents in particulate samples from road environment was developed. Zn was identified as the most suitable elemental marker for TRWP, due to its high concentration in tire tread and the possibility of separation from other Zn sources. The mean concentration of 21 tire samples was 8.7 ± 2.0 mg Zn/g. Before quantifi ...

Abstract:
... This paper seeks to shed light on how ports spread their influence through propagatory activation of other ports in the global oil traffic network from 2009 to 2016. Using a modified linear threshold model, the paper does not attempt to identify a few fixed ports that served as “seeds” for propagation and influence maximization. Instead it identifies active seed port hubs via their diffusion patte ...
