ROAD SAFETY BARRIER

Resumen de: EP4553228A1

The road safety barrier is intended to enhance the security and safety of means of transport moving on the roadway side of public roads.It consists of a set of supporting posts (1), constructed from metal pipes filled with an appropriate amount of concrete (6) up to the free end and anchored by a base plate (2) in the road shoulder, a rail (4) for each pair of posts, and a collar-damper-spacer assembly composed of two cylinders (7) and (8), one placed inside the other and positioned in an eccentric manner to the maximum, in contact, tangent, and welded together by an internal weld seam. An additional cylinder (12) is welded to the outer cylinder (7) by another weld seam, with the wall cut along the generatrices and two flanges forming a collar that attaches to the supporting post (1) of the barrier using bolt and nut assemblies (13). The outer cylinder (7) also features holes through which additional bolt and nut assemblies (14) pass, securing one end of each rail (4) to the collar- damper-spacer assembly fixed to each supporting post (1) of the road safety barrier.

EXPRESSWAY HOLIDAY TRAVEL TRAFFIC VOLUME PREDICTION METHOD BASED ON INFLUENCE OF WEATHER FACTOR

Resumen de: WO2025092100A1

An expressway holiday travel traffic volume prediction method based on the influence of a weather factor, said method belonging to the technical field of road traffic flow prediction. In order to solve the problem of accurate holiday expressway travel traffic volume prediction based on the influence of a weather factor, the method of the present application comprises: establishing a relative influence coefficient between historical weather and travel traffic volume; constructing a travel traffic volume transfer model based on weather data; selecting basic travel traffic volume features, constructing derived travel traffic volume features by means of a cross operation between the basic travel traffic volume features, and then constructing a multiple linear regression model based on historical travel traffic volume features; correcting a predicted travel traffic volume obtained by the multiple linear regression model; correcting a predicted travel traffic volume of the remaining days of a holiday; constructing a layered flow road network travel traffic volume model; and constructing an objective function, and using a reverse gradient propagation method to optimize and solve the layered flow road network travel traffic volume model, so as to obtain an expressway holiday travel traffic volume prediction result based on the influence of a weather factor.

INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD, AND RECORDING MEDIUM

Resumen de: WO2025094872A1

This information processing device is provided with a first acquisition unit, a second acquisition unit, and a generation unit. The first acquisition unit acquires first data regarding vibrations on a road as observed by distributed acoustic sensing using an optical fiber installed along the road. The second acquisition unit acquires second data including at least one of an attribute and a moving state of a vehicle. The generation unit uses the first data and the second data corresponding to the same observation time and observation point to generate road condition data in which the second data of a vehicle is associated with a travel trajectory of the vehicle on the road.
