Transportation Planning and TRANSIMS Microsimulation Model: Preparing for the Transition

Transportation Research Record: Journal of the Transportation Research Board, 2001
The Transportation Analysis and Simulation System (TRANSIMS) was developed as a replacement for the four-step travel demand model. The goal was to provide a simulation system that could analyze issues facing transportation planners such as sustainable development, environmental impacts of proposed projects, and intelligent transportation systems ...

Calibration for TRANSIMS model considering mean and standard deviation value of data

2015 34th Chinese Control Conference (CCC), 2015
Microscopic traffic flow models have been widely used in decision making and evaluation of real transportation systems and the models must be calibrated before use in order to content the credibility of decision and evaluation. For a kind of microscopic traffic flow model (Transportation analysis and simulation system model, TRANSIMS), a new optimal ...

Classical and Contemporary Shortest Path Problems in Road Networks: Implementation and Experimental Analysis of the TRANSIMS Router

Lecture Notes in Computer Science, 2002
We describe and analyze empirically an implementation of some generalizations of Dijkstra's algorithm for shortest paths in graphs. The implementation formed a part of the TRANSIMS project at the Los Alamos National Laboratory. Besides offering the first implementation of the shortest path algorithm with regular language constraints, our code also ...

Development of a Microscopic Traffic Simulation Model Using TRANSIMS: A Case Study in the Southeast Michigan Area

ICCTP 2010, 2010
Bridge and highway construction is a main cause of congestion due to traffic disruption or reduction of traffic capacity from partial or complete lane closure. Currently its mobility impacts and travel pattern changes are analyzed mostly by microscopic traffic simulation models to develop appropriate mitigation measures.

TRANSIM‐A GENERAL PURPOSE PROBLEM SOLVING TOOL

Naval Engineers Journal, 1973
ABSTRACTThis paper describes TRANSIM simulation a a method for solving problems. There is a brief discussion of modeling and its importance. TRANSIM is compared with other general purpose simulators, special purpose simulation, and network analysis techniques such as PERT/CPM. Data requirements for TRANSIM applications are discussed, and a few examples

TranSim: A Simulation Framework for Cache-Enabled Transparent Computing Systems

IEEE Transactions on Computers, 2016
The growing demand on the performance of transparent computing systems requires good cache schemes in order to overcome the prolonged network latency. However, evaluating cache schemes, especially measuring the performance of a transparent computing system with particular cache scheme remains challenging.

What makes a simulation useful? [TRANSIMS]

IEEE SMC'99 Conference Proceedings. 1999 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.99CH37028), 2003
Modern computers make possible a new blending of systems, man, and cybernetics in the detailed simulation of large sociotechnical systems. Several such simulations are currently under development at Los Alamos National Laboratory and elsewhere. When deployed, they will affect the daily lives of hundreds of millions of people and the allocation of ...

Application of Dynamic Value Pricing through Enhancements to TRANSIMS

Transportation Research Record: Journal of the Transportation Research Board, 2007
In the past decade, transportation agencies have become increasingly interested in a high-occupancy toll (HOT) lane value pricing system, especially one with a dynamically varying toll system that depends on the congestion levels in the HOT lanes. HOT lane users are influenced by many factors, including toll prices, savings in time, and purpose of the ...
