The problem of computing the intersection of parametric and algebraic curves arises in many applications of computer graphics, geometric and solid modeling. Previous algorithms are based on techniques from elimination theory or subdivision and iteration and are typically limited to simple intersections of curves. Furthermore, algorithms based on elimination theory are restricted to low degree c...

Leveraging the accuracy and consistency of vehicle motion control enabled by connected automated technology, we propose rhythmic (RC) scheme that allows vehicles to pass through an intersection in a conflict-free manner with preset rhythm. The rhythm enables proceed at constant speed without any stop. RC is capable breaking limitation right-of-way can only be allocated nonconflicting movements ...

Uncontrolled intersections are the intersections where there are no external signs or signals to control the movement of vehicles. In mixed traffic conditions priority rules are often violated by the road users. In All-way-stop-controlled intersections (AWSC), the vehicle should stop themselves before they enter the intersection and should check whether any vehicles are present in the other app...

Accurate estimation of saturation flow rate is a prerequisite for accurate estimation of level of service and delays of signalized intersections. Saturation flow rate of intersections depends on many factors, including traffic behavior and culture. One of the important problems of traffic behavior in Iran is the violation of law at the physical region of intersections. The main purpose of this ...

Suppose that closed subschemes X ⊂ Y ⊂ P differ at finitely many points: when is Y a flat specialization of X union isolated points? Our main result says that this holds if X is a local complete intersection of codimension two and the multiplicity of each embedded point of Y is at most three. We show by example that no hypothesis can be weakened: the conclusion fails for (a) embedded points of ...
