In weaving section due to a strong need for lane changing, a type of turbulence is created in traffic flow; so, the speedand the capacity of the weaving section decreases. Therefore, investigation of the weaving section is very important.However, due to shortage of the manual for urban principal arterials (highways), calibration of these models is necessary.One of these models...

The core methodology of the Highway Capacity Manual (HCM) 2010 for freeway analyses is based on Free-Flow Speed (FFS). Moreover, weaving segments are major elements of freeway facilities that form where two one-way traffic streams intersect by merging and diverging maneuvers. Hence, this study used three different methods to compute FFS of a ramp-weaving segment, and then employed the proposed ...

Calibration is a conventional method which is utilized to adapt traffic models based on local situations in order to achieve best results. One of the issues regarding the efficiency of this method is whether traffic models should be calibrated only in one or two major cities of a country or calibrated based upon a comprehensive selection of cities. Therefore, this study, which has used the actu...

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...

ct such as color or width inconsistencies, slubs, broken ends, etc. The tests on the quality of yarns are usually performed at the output of spinning-mills. Quality test runs for looms and knitting machines require interruption of the weaving process. This interruption is not practically feasible for the machines that are intended for large production runs of fabric rolls. The quality test is c...

1 Weaving is defined as the crossing of two streams travelling in the same direction along a 2 significant section of the road without the assistance of traffic control devices. Merging and 3 diverging vehicles need to make one or more lane-changes in a limited space and time, 4 determined by the weaving section length. This situation creates intensive lane-change 5 maneuvers, combined with hea...

In order to ensure an acceptable quality even at the highest spinning or weaving speeds, tensile instruments and testing conditions have to be improved. Therefore, a new high-speed dynamometer and a new method to subject yarns at strain rates similar to those found in current textile operations have been developed. This high-speed dynamometer has then been used to investigate the influence of h...

purpose : to determine the effect of carpet weaving on refractive errors methods : in this cross sectional study, carpet weavers and non-weavers in the normal population of mashhad were regarded as exposed and non-exposed groups, respectively. a carpet weaver was a person who wove carpets 7 hours a day for at least 2 years. the non-weavers group was selected from the population of mashhad throu...

When late-binding of advice is used for incremental development or configuration, implementing advice weaving using code rewriting external to the VM can cause performance problems during application startup. We present an interpreter-based (non-rewriting) weaver that uses a simple table and cache structure for matching pointcuts against dynamic join points together with a simple mechanism for ...
