چکیده

We describe three tra c microsimulations which operate at di erent levels of delity. They are used to iteratively generate a self-consistent route-set based upon microsimulation feedback. We compare the simulation results of all three simulations to aggregated turn count data of actual eld measurements. Acknowledgments { We thank A. Bachem and R. Schrader for supporting MR's work as part of the tra c simulation e orts in Cologne (\Forschungsverbund Verkehrsimulation und Umweltwirkungen NRW" [1]). We also thank them, plus C. Barrett, P. Wagner, Ch. Gawron, S. Krau , and M. Schreckenberg for help and discussions. We thank the TRANSIMS research (M. Marathe, R. Jacob, and others) and software (M. Stein, P. Stretz, D. Roberts, B. Bush, K. Bergbigler, and others) teams for discussions and the processing of the data which served as input for the micro simulation. The North Central Texas Council of Government (NCTCOG/Ken Cervenka) provided road network and origin-destination data on which the simulations were based. Use of computer facilities at the Center of Parallel Computing (Cologne) and computing time on the workstation cluster at TSA-DO/SA is gratefully acknowledged. We further thank all people in charge of maintaining the above mentioned clusters. The work of MR was supported in part by the \Graduiertenkolleg Scienti c Computing Koln". This work was performed in part at Los Alamos National Laboratory, which is operated by the University of California for the U.S. Department of Energy under contract W-7405-ENG-36 (LA-UR 98-2944).

Experiences with a Simpliied Microsimulation for the Dallas/fort worth Area

We describe a simple framework for micro simulation of city traac. A medium sized excerpt of Dallas was used to examine diierent levels of simulation delity of a cellular automaton method for the traac ow simulation and a simple intersection model. We point out problems arising with the granular structure of the underlying rules of motion.

Investigation on Forming of Titanium Bipolar Plates Using Micro-stamping Process

Micro-stamping process is one of the most cost-effective methods to manufacture metallic bipolar plates (BPPs). This research investigates the forming of titanium thin sheet as a potential candidate for BPPs in proton exchange membrane fuel cell (PEMFC). In this regard, the process was first simulated using finite element (FE) code Abaqus. Afterward, experimental tests were implemented and the ...

Eeect of Non-uniform Traac on the Performance of Multistage Interconnection Networks

Multistage interconnection networks are used to connect processors to memories in shared memory multiprocessor systems. The performance evaluation of such networks is usually based on the assumption of uniform memory reference pattern. Hot spots in such networks give rise to non-uniform memory reference pattern and result in a degradation in performance. A comparison of performance between unbu...

The Primacy of Teacher Imperative Commentaries in the Improvement of Iranian English Majors’ Writing Ability

In this study, the researchers investigated a critical aspect of EFL/ESL writing pedagogy-the impact of teacher written commentary on student writer’s earlier drafts. Compositions of 80 Iranian undergraduate English majors were commented on using a trio of imperatives, statements, and questions on both content and form. Overall, the results indicated that the comments in the imperative form hel...
