Evaluating Operational Performance of Intersections Using SIDRA

Evaluating the Operational Features of an Unconventional Dual-Bay U-Turn Design for Intersections

Median U-turn intersection treatment (MUTIT) has been considered an alternative measure to reduce congestion and traffic conflict at intersection areas. The MUTIT is sometimes difficult to implement in the field because it requires wide median on arterials for U-turn vehicles. The objective of this study is to introduce an unconventional U-turn treatment (UUT) for intersections which requires l...

Safety and Operational Impacts of Alternative Intersections

Evaluating and Enhancing the Operational Performance of Public Bus Systems Using GIS-based Data Envelopment Analysis

In this paper, the baseline performance level of Al Ain Public Bus Service is evaluated using Data Envelopment Analysis (DEA) based on some selected input (travel time per round trip, total number of stops, total number of operators, total number of buses) and output (daily ridership and vehicle-kilometer) variables. Two types of scenarios were developed and tested. The first set of scenarios a...

An Investigation Into Improving Runtime Performance in Evaluating a Mobile Ad- Hoc Operational Scenario Using OPNET

-Quantifying the end-to-end performance of evolving DOD communication networks is highly desired by the component and network designers during all phases of the development process. Analytical techniques, inlab testing and field demonstrations are all necessary toward this end but all have limitations in addressing this need. Simulation remains a primary method with which to generate end-toend ...

Operational macroscopic modeling of complex urban road intersections

This article describes a new approach to the macroscopic first order modeling and simulation of traffic flow in complex urban road intersections. The framework is theoretically sound, operational, and comprises a large body of models presented so far in the literature. Working within the generic node model class of Tampere et al. (forthcoming), the approach is developed in two steps. First, bui...
