Traffic engineering studies such as validating Highway Capacity Manual (HCM) models require complete and reliable field data. However, the wealth of Intelligent Transportation Systems (ITS) data is sometimes rendered useless for these purposes because of missing values in the data. Many imputation techniques have been developed in the past with virtually all of them imputing a single value for ...

Vehicle delay at a signalized intersection is among the widely used performance measures of efficiency at a signalized intersection. The Highway Capacity Manual (HCM) uses this performance measure to report the level of service at a signalized intersection. This performance measure is also used to estimate travel time along the arterials. With the advent of technological advances in the field o...

KREISIG is a computer simulation program, firstly developed by Munawar (1994) in Germany to optimize signalized roundabout. The traffic movement is based on the car following theory. Turbine method has been implemented for signal setting. The program has then been further developed in Indonesia to meet the traffic characteristics in Indonesia by adjusting the sensitivity of the drivers. Trial a...

This paper considers the welfare impacts of a range of franchising regimes for congestible highways. For a single road in isolation, it is shown that a competitive auction with the level of road use as the decision criterion produces the socially optimal road (in terms of capacity and toll level) as the equilibrium outcome, provided constant returns to scale characterize highway operations. The...

F the past 20 years weaving segments have been analyzed and designed using the methodologies and procedures provided in the 1965 Highway Capacity Manual (HCM).’ With the increase in urban growth in the mid-1960s, it was quickly realized that the procedures provided in the 1965 HCM for the analysis and design of weaving segments were in need of a critical review. In 1969 the National Cooperative...

recent years have brought a great deal of expansion to the economic systems of developing countries. although they serve as vital link of economic activities, the transportation network of these countries have not grown proportionally. since transportation investments is a a substantial portion of the national budget, a good knowledge of each mode's various characteristics is essential, wh...

Abstract The majority of roads in most countries are two-lane highways. These lanes quickly reach their capacity and must be upgraded on a regular basis. To do so, we first determine the street. primary objective this study was to effect carriageway width, radius horizontal curve, gradients Passenger Car Unit (PCU) values as well undivided Highways, more importantly, develop multiple linear reg...
