This paper gives the definition of one parameter stopping time σ field F T+ and discusses some features of F T+ only under the condition of leaving out one parameter σ fied (F t) t∈R+ right continuity.

This paper studies the properties of some generalized capacities and proves (a) any convex pre-capacity is a convex capacity if it has the C-right continuity, i.

Aiming at the problem of traffic capacity in the signalized intersection of city,this article puts forward a traffic organized method on which the left-turn vehicle in the intersection making continuous right-turn to realize leftturn is based, providing a new way of thinking for increasing the traffic capacity of the signalized intersection.
