“…While authors explain the calibration procedure, their own experience in demonstrating the effects of speed harmonization is strongly dependent on drivers' compliance [16] and the results cannot be compared to real-world studies (as presented in this paper). Similar results were also discussed in literature [17][18][19].…”

Road construction and maintenance activities cause traffic congestions and delays and present challenges for ensuring the safety of both motorists and road workers. While urban areas are well-equipped with traffic devices, in the case of highways our chances to collect traffic data and control traffic flows may be limited. Then the use of a temporary Highway Traffic Management System seems to be a suitable solution. Although the impacts of its deployment are addressed by many theoretical studies and demonstrated on traffic simulation models, there are not many references dealing with field tests. We provide results of the practical evaluation of the temporary Highway Management System installed and tested on the main highway in the Czech Republic during the road works period. Before-after analysis of collected traffic data was performed to prove the importance and positive impact of the proposed solution. We demonstrate an over 20% increase in the capacity of the roadwork zone and an almost 30 seconds decrease in average delay for one vehicle Highway administrators can use the results to justify investments into the temporary deployment of mobile traffic management systems.

“…This clearly shows that the main proportional reduction happened only in the property damage only (PDO) crashes, which commonly occur during traffic congestion periods. The steep increase in the rates of injuries could be due to the fact that roads experienced significantly low traffic volumes during the peak restrictions period, which resulted in increased aggressive and speeding behaviour (Bényei & Golarits, 2002;Doucette et al, 2021;Oskarbski et al, 2020). Therefore, increased speeding behaviour could have triggered more severe outcomes from crashes.…”

the main objective of this study is to investigate the status of traffic safety and the public perception of traffic safety during the during cOViD-19 pandemic. three different data sets are used in this study: road crash and traffic violation data from Qatar, and two separate questionnaire surveys (from general public and road safety experts). Results showed that during cOViD-19 period, the total number of crashes in Qatar significantly reduced during the pandemic compared with the previous 5 years. however, the rates of serious and fatal injuries significantly increased. Regarding the general public perceptions, more than 80% reported that roads became safer while driving behaviours improved during the pandemic. On the other hand, more than 50% of the experts disagreed that roads became safer, 55% disagreed that driving behaviours improved and 70% agreed that less attention from governments was directed toward road safety during the pandemic. the findings from this study could help policy makers to understand the road safety status during the pandemic to make appropriate adjustments in the traffic laws and regulations on a temporary basis. this could help in reducing crash-related injuries and as a result reduce pressure on health and other emergency services.

“…Reference [ 3 ] addressed the issues associated with expert assessments and statistical studies commonly used to evaluate the impact of intelligent transport system (ITS) services on road safety. The work built upon an approach based on surrogate safety measures calculated and calibrated with the use of simulation techniques and a driving simulator to achieve traffic efficiency and road safety.…”
