“…Vehicles are prone to lateral slip and rollover while driving on curves. In general, a slip precedes a rollover, therefore, it is vital that a vehicle does not slip to ensure that no rollover occurs ( 5 ).…”

“…Existing urban road design specifications for intersections and related provisions for curb radii are relatively standard: most focus on traffic volumes, vehicle types, and travel and pedestrian safety ( 5 ). Fei et al constructed a microscopic simulation model for intersection turning radius design with the goals of minimum pedestrian delay and maximum safety at intersections ( 6 ).…”

“…Different curb radii for a given design speed will affect road users’ perceptions, which are usually embodied by lateral force coefficients, lateral acceleration, and lateral acceleration changes ( 9 ). Yang points out that when a car is driven on a curve, the main factor causing driving discomfort is the centrifugal force generated in the horizontal vertical direction ( 10 ), which acts at the vehicle’s center of gravity, off the level of the circular direction ( 5 ).Passengers will be affected by centrifugal force in the process of turning, and with increases in the force, feelings will gradually transition from comfortable to unbearable. The lateral force coefficient is defined as the lateral force per unit of vehicle weight, representing the stability of a vehicle running into curves and the associated passenger comfort.…”

The huge waste of urban road resources caused by large turning radii of intersections has become a universal concern in traffic engineering. Here, an approach for determining curb radius at intersections is proposed using lateral acceleration to reflect ride perceptions, bringing human-oriented concepts into urban intersection design. First, we classified three kinds of ride perceptions into comfortable/uncomfortable but acceptable/unacceptable, after which the lateral acceleration and ride perceptions were obtained by ride perception experiments. The lateral acceleration critical values for each ride perception were obtained using the Raff critical gap method. Finally, we calculated the intersection curb radius based on the critical values, and verified vehicle safety under the recommended intersection curb radius. The results showed that the intersection curb radius based on the proposed approach was less than the specified value and safety was verified, indicating that enormous land resources could be saved were this methodology applied to intersection design.

A Projection Pursuit Regression method by using Hermite Polynomial is put forward to make modeling and forcasting of corrosion data, because of small sample of acumulation data of metal material corrosion in atmosphere, Multi-dimensional Properties and Non-orthogonality of influence factors. Analyses and prediction of atmospheric corrosion data of a metal are made by using this method. Compared with PCA+SVM method, this method improves significantly the accuration of prediction and correctness of corrosion vehavior trend. The result proves that the Hermite Polynomial Projection Pursuit Regression method has great huge advantage in data analysis of steel corrosion in atmosphere.
