Abstract Road traffic system is a complex system in which human participate directly. In this system, human factors play a very important role. In this paper, a kind of control signal has been designated at a given site (i.e., signal point) of the road. Under the effect of control signal, the drivers will decrease their velocities when their vehicles pass the signal point. Our aim is to transit the traffic flow states from disorder to order, and then improve the traffic safety. We have tested this technique for the two-lane traffic model that is based on the deterministic NaSch traffic model. The simulation results indicate that the traffic flow states can be transited from disorder to order. Different order states can be observed in the system, and these states are safer.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
