Safety aspects of freeway weaving sections
One source of vehicle conflict is the freeway weaving section, where a merge and diverge in close proximity require vehicles either entering or exiting the freeway to execute one or more lane changes. Using accident data for a portion of Southern California, we examined accidents that occurred on three types of weaving sections defined in traffic engineering: Type A, where every merging or dive...

متن کاملGeometric Approach to Modeling Vehicular Speeds through Simple Freeway Weaving Sections
1 a typical simple one-side weaving section, as shown in Figure 1, the geometric variables of the weaving section are the length of the weaving section, L, and the number of lanes within the weaving section, N. Length of the weaving section is measured from a point where the entrance gore is 2 feet wide to a point where the exit gore is 12 feet wide. Vehicular flow is categorized into four gene...
متن کاملMonitoring Weaving Sections
Executive Summary Traffic control in highway weaving sections is complicated since vehicles are crossing paths, changing lanes, or merging with through traffic as they enter or exit an expressway. There are two types of weaving sections: (a) single weaving sections which have one point of entry upstream and one point of exit downstream; and (b) multiple weaving sections which have more than one...
متن کاملImplementing Estimation of Capacity for Freeway Sections
Based on the stochastic concept for freeway capacity, the procedure of capacity estimation is developed. Due to the fact that it is impossible to observe the value of the capacity and to obtain the probability distribution of the capacity, the product-limit method is used in this paper to estimate the capacity. In order to implement estimation of capacity using this technology, the lifetime tab...
