Disclosed herein are an apparatus and method for controlling traffic at an autonomous intersection. A monitoring unit monitoring vehicles located within a predetermined service radius of an intersection. A collision zone information management unit classifies the service radius into a plurality of zones based on the results from the monitoring unit, and manages information about collision zones. A collision prediction unit predicts the possibility of collision of a target vehicle in the zone in which the target vehicle is located, based on vehicle information transmitted from the target vehicle, and calculates an estimated time of collision. A priority determination unit predetermines a priority of the target vehicle based on the estimated time of collision and calculates an expected entering time corresponding to the priority. A communication unit transmits control information about the target vehicle to the corresponding vehicles to control respective vehicles.

A platoon model allows improved prediction of preceding vehicle future state. In this context, the preceding vehicle is a vehicle immediately ahead of the host vehicle, and the dynamic state of the preceding vehicle was predicted based on data received from one or more vehicles in the platoon. The intelligent driver model (IDM) was extended to model car-following dynamics within a platoon. A parameter estimation approach may be used to estimate the model parameters, for example to adapt to different driver types. An integrated approach including both state prediction and parameter estimation was highly effective.

The invention describes a flow control method to control HS-DSCH data streams over UTRAN Iub and Iur interfaces. Two credit assignment schemes are also described. A radio network node at which the flow control method executes is proposed. Finally a computer program product for execution of the flow control method and the credit assignment schemes is described. The control of separate user data flows is coordinated by Node-B and data transport over the Iub and Iur interfaces is adapted to data transfer over the Uu interface. The main advantage is that buffering can be primarily maintained in SRNC. It is shown that the proposed flow control method can significantly reduce Node-B's buffer level when compared to a scheme where the control of individual data flows is performed independently of each other. It is also shown that the negative impact on the quantity of flowing data is generally minor.

PCT No. PCT/JP98/05062 Sec. 371 Date Sep. 8, 1999 Sec. 102(e) Date Sep. 8, 1999 PCT Filed Nov. 10, 1998 PCT Pub. No. WO99/24148 PCT Pub. Date May 20, 1999This invention is related to a wet gas process which would not require a spray pump, and which would allow the absorption liquid to be recovered smoothly even if the flow velocity of the gases entrained to the liquid should decrease. A wet gas processing apparatus in which the absorption liquid collected in the first liquid storage tank is sprayed in a specified direction (which may be upward, horizontal or downward) by a discharge unit consisting of spray nozzles (14) or the like in the absorption tower. The sprayed liquid is brought into contact with the exhaust gases which are conducted into the tower, and the targeted components of the gases are absorbed and removed. This processing apparatus is distinguished by the following. The first liquid storage tank for the absorption liquid comprises a pressure tank (11) which generates a pressurized gas in the space above the surface of the collected liquid (11a). The increased pressure of the pressurized gas is employed to spray the liquid collected in the pressurized tank from the spray nozzle unit in the absorption tower. This apparatus is further distinguished as the following. This invention has overflow ports which generate a virtually horizontal overflow or source flow. The absorption liquid propelled by the overflow ports makes orthogonal contact with the flow of exhaust gases, which results in both atomization of the liquid and liquid-vapor contact.
