If the authentic body does not define such methodology the final decision score in 100-score will be converted as follows [29]. Firstly, the performance indicator is measured in different appropriate unit.…”

The paper reviews several strategies of restricting or separating trucks from the regular traffic stream. Typical truck restriction policies focus on leftmost lanes restriction, which has been shown by several studies to have some advantages. However, those studies clearly show that vehicle queue lengths in the vicinity of critical merging areas increase significantly as the percentage of trucks increases. Therefore, this study examines a different policy—one which investigates traffic efficiency gained by restricting heavy truck traffic in one direction—in this case, westbound on Highway 1 in Israel—during afternoon peak hours. Similar policies of utilizing a specific vehicle category (e.g. passenger cars or trucks) in different daily time periods or physical separation of homogenous traffic of passenger cars in the inner lanes and mixed traffic in the outer lanes, were recommended in Italian motorways and in New Jersey Turnpike dual-dual freeways respectively.Highway 1 is a freeway connecting Jerusalem and Tel Aviv that passes by Ben-Gurion International Airport. The major objective of this study is to estimate the benefit of restricting truck traffic in the traffic stream according to three traffic-flow parameters: average travel time, total travel time, and average traffic speed. Analysis of the results, which consider the significant differences of 30-minute time period samples (“before-after” truck restriction), shows that prohibiting trucks in all lanes in one direction during the peak afternoon period of 16:00-18:00 improved all three traffic flow parameters by 8%-12%. Generally a steep grade from which truck traffic is banned is correlated with an improvement in traffic flow. In our case, Highway 1 road segments 1 and 2 and 4, which have steep grades (longitudinal grades), incorporated the most significant improvements in the traffic stream parameters examined.

“…Because the eigenvalues of some matrices are sensitive to perturbations, an inverse square law analysis was employed here to test the sensitivity of the estimated weights for levels 1 and 2. Although this law generally says that a specified physical strength ( p ) is inversely proportional to the square of the distance ( 2 / 1 r ) from the source, it is believed to apply well to other areas of perception or thought (Saaty 1990;Yang and Regan 2012). Table 6 shows the results of an inverse square law analysis.…”

“…They point out that their earlier prioritization approach which was used by the Indiana Department of Transportation in the U.S has several deficiencies, but that the proposed AHP method, based on a series of sensitivity analyses, appeared to be sound. The AHP method improves the ability to analyze multiple and conflicting priorities and allows decisionmakers to integrate qualitative and quantitative aspects simultaneously (Kirkwood 1996;Bhushan and Rai 2004;Sohn 2008;Tanadtang et al 2005;Yang and Regan 2012). Figure 2 shows the overall methodology used to evaluate the adequacy of road management equipment operations in regional offices.…”

This paper presents a methodology for effective operation of road management equipment. The primary goal of this research is to aid public agencies with day-to-day road management within limited financial resources. In order to demonstrate the value of this approach, we present a case study using data collected for eighteen regional offices of the South Korean Ministry of Land, Transport and Maritime Affairs. Road agencies want to know whether they currently have sufficient equipment to handle work demands, but this is difficult to predict. Thus, a methodology was developed to employ historical data on road management equipment, and two evaluation indicators were identified. Using our method, equipment can be classified into four groups: 1) frequently used and important, 2) relatively less used and important, 3) barely used and low importance, and 4) frequently used and low importance. In our case study we show that these can be used by regional offices to determine either to lend or borrow among offices or to consider purchase for both long and short term use.While our study focuses on a specific case study, the overall methodology can easily be applied by similar decision makers in other countries.
