“…The first-order constructs (dimensions) associated to second-order constructs that are reflective had loadings that were beyond 0.7 thresholds, which is the acceptable measurement. The observation of the composite reliability was done by assessing the construct reliability [19]. The constructs that are related to all the second order had the required construct reliability which were greater than 0.7 [20] suggested (Table 1).…”

Many previously conducted empirical studies have displayed mixed findings about the influence of internal factors within an organization on the management of risk among construction companies. Hence, there is a need for introducing a moderating variable to this field of study. The aim of this research was to confirm whether coercive pressure plays a significant role in the relationship between the management of risk in construction and factors within the organization. Therefore, this study examined the influence that internal organizational factors and coercive pressure have on the management of construction risk through the lens of discouragement and organizational control theory, and institutional theory. Data were collected through the distribution of questionnaires involving 165 workers working in the Malaysian Peninsular construction companies, and the analysis was performed by means of partial least squares structural equation modelling. Results revealed a positively significant connection between internal organizational factors and the management of construction risk. Also, coercive pressure and the management of construction risk has a positively significant relationship. Coercive pressure mediated the connection that organizational internal factors had with the management of construction risk. A discussion of the research implications was done from the point of view of Malaysia. In conclusion, the reduction of risk incidents in the process of carrying out construction activities is being facilitated by active leadership and organizational culture. In addition, the rate and period at which accidents occur during and after the completion of construction activities are reduced by coercive pressure. In the same way, some influential internal factors of organizations as well as the introduced coercive pressure in the process of managing construction risk have established that many construction companies that apply the necessary internal factors as well as the coercive pressure introduced by the government are able to make delivery of their construction task at the specified cost, time, and qualities, thus establishing them as the correct standard for measuring a well-constructed project.

“…Wolshon [19,20] introduced the application of variable lane technology in the USA and pointed out that there is also a lack of operational variable lane design standards in the USA. Bade [21] designed a 3 km long variable guidance lane system in the Salt Lake City area. It was coordinated and controlled by traffic signals.…”

The purpose of setting up variable guidance lanes is to ease the traffic pressure on lanes with more traffic under the condition of ensuring the traffic capacity of the intersection. This study proposes a bi-level model-interactive relationship between variable guidance lane design and signal control and carry out a case study for a road in Wuhan, China. The design plan for the goal, combined with the design plan of the variable guidance lane, optimizes the signal timing plan of the intersection. A real case is modeled in VISSIM to simulate the design scheme of variable guidance lanes to verify the reliability and effectiveness of the bi-level model. The results showed that the average vehicle delay at the intersection was reduced by 20.65% after the bi-level model was optimized. The average error between model calculation results and simulation results is 9.88%. Moreover, the influencing factors of the proposed model are also carried out. The results show that when the traffic flow is greater than 1,000 pcu/h, the optimization effect of the model is more significant. When the traffic capacity gradually increases, the average vehicle delay calculated by the model is smaller. The design scheme and signal timing scheme proposed by the bi-level model can ensure the overall traffic efficiency of the intersection, improve the traffic efficiency of the traffic-stressed lanes, and further promote the space-time resource utilization of the intersection, optimize the space-time resources of the road network, and provide a scientific basis and new ideas and methods.

“…For a practical interpretation and implementation of the safety requirements for self-driving vehicles, it is necessary to understand what reliable and safe behavior really means (Bede and Péter, 2011). For example, a HAD car must be able to handle traffic rules, the geometry and topology of its surroundings, and must be able to interpret the meteorological system, but also rare, difficult-to-predict road hazards (Kiss, 2022).…”

The main task of the article is to define the critical minimum number of tests for the dynamics of a traffic node in autonomous driving based on critical phenomena, i.e. the percolation theory. The critical (minimum) number of tests of a node means how we can represent the traffic dynamics of a node with critical, percolating path using a "state-following state" system on the graph. The test cases along the percolation path, i.e., those involved in the formation of the new phase, represent the entire test system and are minimal. In the article we show that only less than 10 of the 640 tests to be performed have to be realized and are representative for release processes.
