Abstract: Pore-measuring method and mercury intrusion method based on digital technology can detect the hole structure of cement concrete with the aim to ascertain the relationship between frost durability degradation of cement concrete and pore structure. Meanwhile the influence of pore structure on the anti-frost performance is analyzed. The results show that additive like excellent air-entraining agent can obviously perfect the pore structure of cement concrete so that the anti-frost performance is heightened.

TL;DR: Through the traffic investigation and data analysis of an intersection in Harbin, an intersection optimization plan is proposed from the aspect of the space and time transportation design optimization and the conclusion that the new plan can improve the traffic efficiency of intersections is deduced.
Abstract: Through the traffic investigation and data analysis of an intersection in Harbin,an intersection optimization plan is proposed from the aspect of the space and time transportation design optimization,as well as the intersection′s present situation and the optimization plan are studied with VISSIM transportation simulation software. By comparing old and new plans,the conclusion that the new plan can improve the traffic efficiency of intersections is deduced.

TL;DR: It studies the relationship between speed difference and crash rate, using speed and accident data of nine freeway in China to show that the accident rate has obvious correlation with the dispersion of speed.
Abstract: It studies the relationship between speed difference and crash rate,using speed and accident data of nine freeway in China. Research shows that the accident rate has obvious correlation with the dispersion of speed. According to the accident rate and speed scatter distribution,several kinds of model are fitted,The significant level of F as well as R2 are analyzed arriving at the index distribution model of accident rate and speed standard deviation. It is significant to guaranteeing the traffic safety on expressway.

TL;DR: The fuzzy control model for urban traffic lights at single intersection is built from the perspective of cybernetics and has better control effect which reduces vehicle average delay at the single intersection.
Abstract: The fuzzy control model for urban traffic lights at single intersection is built from the perspective of cybernetics The modeling is designed by imitating the decision-making process of traffic policemen leading and unblocking traffic flow The specific control algorithm and fuzzy controller are introduced in detail afterward By using the Simulink tool in Matlab, the fuzzy control model is simulated and analyzed Comparing with the timed traffic lights control solution, the fuzzy control model has better control effect which reduces vehicle average delay at the single intersection
