A method for forecasting owner monthly construction project expenditure flow

Skitmore, Martin - 1998

Under the normal conditions of construction contracts, the client is obliged to pay the contractor in monthly instalments. The amount of each instalment is based on the value of construction work actually produced in the previous month and forecasts are needed in advance of the likely value of...

Models of vehicular traffic: An engineering perspective

Chakroborty, Partha - In: Physica A: Statistical Mechanics and its Applications 372 (2006) 1, pp. 151-161

The aim of the paper is to present an engineer's viewpoint of traffic streams and their models both at the macroscopic and microscopic levels. The paper concentrates on two classes of macroscopic models (namely, stream description models and travel time estimation models). At the microscopic...

Local cluster effect in different traffic flow models

Herrmann, Matthias; Kerner, Boris S - In: Physica A: Statistical Mechanics and its Applications 255 (1998) 1, pp. 163-188

A comparison of diverse effects of self-organization in traffic flow in microscopic and macroscopic traffic flow models … is made. It is shown that traffic flow models which are mathematically different, belong to the same universality class … of traffic flow models in the sense of their possibility to reproduce properties of real traffic jams, if they show the …
