DYNASMART-P version 1.3.0 Dynamic
Network Assignment-Simulation Model for Advanced Roadway Telematics
(Planning
version)
DYNASMART-P 1.3.0 now
comes with a powerful GIS
data import and network editing tool - DSPEd
1.3.0. DSPEd facilitates the
deployment of DYNASMART-P via click-and-drag graphical
user interface as well as GIS import capability. DYNASMART-P (#DYNA) is
priced at $1750, with a
limited-support version (#DYNA.UN) available for $1000.
DYNASMART-P was previously
developed and maintained by researchers at the University of Maryland
(UMD),
and is now supported by the FHWA DYNASMART-P support team. The
fully
supported version includes full technical assistance and response to
specific
issues. The limited support version allows access to McTrans
only,
for responses to frequently asked questions. Hardcopy help
documents are
not available, but electronic help documents are included within the
software
at no extra charge. A single license allows the end user to
install the
software on any number of computers within the immediate office
location. Click here to

Windows. DYNASMART-P supports
transportation network planning and traffic operations decisions,
including
evaluation of ITS deployment options, through the use of
simulation-based
dynamic traffic assignment. This tool combines (1) dynamic network
assignment
models, used primarily in conjunction with demand forecasting
procedures
for planning applications, and (2) traffic simulation models, used
primarily
for traffic operational studies. DYNASMART-P provides the capability to
model
the evolution of traffic flows in a traffic network, which result from
the
decisions of individual travelers seeking for the best paths en-route
over
a given planning horizon. It overcomes many of the known limitations of
static
tools used in current planning practice. These limitations pertain to
the
types of alternative measures that may be represented and evaluated,
and
the policy questions that planning agencies are increasingly asked to
address. DYNASMART-P defines a
new generation of transportation planning
methodologies, which can interface readily with existing four step
procedures,
yet provides a meaningful jump in the range and type of measures that
can
be evaluated. Because it considers the time-varying nature of traffic
flows,
it is expected to produce more useful estimates of state variables such
as
speeds, queue lengths, delays, and congestion effects to better assess
the
functional and environmental impacts of a variety of traditional and
emerging
transportation planning measures, including the deployment of ITS and
non-ITS
technologies.
DYNASMART-P requires input data commonly used by the traditional traffic assignment and simulation models, particularly with regard to network representation and spatial demand loading patterns. The input data vary with the network being analyzed and the level of detail required by the user. Complexity of the network could range from a linear freeway network to an integrated network with High-Occupancy Vehicle (HOV) lanes, High-Occupancy Toll (HOT) lanes, ramp metering, transit services, possibly incidents and signal controlled intersections on surface streets. Applications to date have included metropolitan and regional networks with up to 35,000 nodes and 100,000 links, with nearly one million vehicles simulated over horizons of several hours. DYNASMART-P produces a wide array of output information to assist users in performing detailed traffic analysis. The output report contains Measures of Effectiveness (MoEs) commonly used by traffic engineers, such as volumes, speeds, travel times, delays, etc. DYNASMART-P also produces an individual vehicle trajectory file, which is very useful for research purposes. In addition, through its intuitive graphical user interface (GUI), DYNASMART-P provides the user with the means to view simulation results and other characteristics through various graphical formats, both static and animated. With rich built-in features, DYNASMART-P can be used to evaluate complex strategic and operational network planning decisions and to produce policy-relevant traffic assignment results for planning analyses. The potential applications include:
