TransCAD continually breaks new ground as a tool for transportation planners by improving, streamlining, and accelerating the demand modeling process. TransCAD is the only package designed to facilitate the implementation of best practices for travel forecasting and to provide a mechanism for advancing the state of the art in transportation modeling.

Modeling with TransCAD is not limited to urban or regional demand forecasting, but is directly applicable for modeling passenger and freight flows at the state, national, and international level. Travel forecasting models are used to predict changes in travel patterns and the utilization of the transportation system in response to changes in regional development, demographics, and transportation supply. Modeling travel demand is a challenging task, but one that is required for rational planning and evaluation of transportation systems.

TransCAD is an extremely capable and robust GIS that includes many advanced features for transportation that are not available in other general purpose GIS software products. There are many reasons why it is valuable to have a GIS as an integral part of a travel demand forecasting package. First, GIS makes it possible for planning models to be much more accurate. For example, network distances are based on the actual shape of the road network and a correct representation of highway interchanges.

Second, the whole modeling process is more efficient. Data preparation is greatly facilitated and the database and visualization capabilities catch errors before they cause modeling problems. With TransCAD, you and others will have an easier time understanding how the model components behave.

For all of these reasons, less staff time is needed to implement and maintain travel models. In TransCAD, different modeling equations can easily be derived and applied for different geographic subareas.

Similarly, TransCAD brings new and much-needed capabilities for measuring geographic accessibility. Because they have similar architectures, TransCAD is the planning package that integrates best with other institutional GIS software systems. TransCAD software is unique among travel demand forecasting packages in many respects:.

TransCAD includes comprehensive tools for trip generation, trip distribution, mode split modeling, traffic assignment, and all related matrix and network processes. TransCAD includes all of the traditional 4-step models and significant variants, quick response models with reduced data requirements, and advanced disaggregate demand models.

Caliper continually enhances TransCAD to incorporate the most up-to-date methods for demand forecasting. The goal of trip production is to estimate the number of trips, by purpose, that are produced or originate in each zone of a study area.

Trip generation is performed by relating frequency of trips to the characteristics of the individuals, of the zone, and of the transportation network.

There are four primary tools for modeling trip production, all of which are provided in TransCAD:. The goal of Trip Attraction is to predict the number of trips attracted to each zone or to a particular land use. In many ways, estimating attractions is similar to estimating trip productions. Thus, cross-classification, regression, and discrete choice methods can be used to estimate the number of trips attracted to a zone.

In trip generation, separate models are used to predict productions and attractions. This invariably leads to a discrepancy between the number of intraregional trips produced in an area and the number of trips attracted to an area. To conserve trips, balancing methods are provided so that the number of attractions equals the number of productions. Trip generation and attraction can be balanced flexibly to productions or attractions or a linear combination thereof.

Trip distribution models are used to predict the spatial pattern of trips or other flows between origins and destinations.

Models similar to those applied for trip distribution are often used to model commodity flows, retail trade, and store patronage. TransCAD provides numerous tools with which to perform trip distribution, including procedures to implement growth factor methods, apply previously-calibrated gravity models, generate friction factors, and calibrate new model parameters.

In addition to doubly constrained trip distribution models that ensure that the output flow matrix from trip distribution matches the input productions and attractions, TransCAD includes tri-proportional models which allow for another dimension of constraints.

In tri-proportional models, groups of cells in the P-A flow matrix are required to sum to specified values. TransCAD allows the additional dimension to be applied for both growth factor and gravity models.

Mode choice models are used to analyze and predict the choices that individuals or groups of individuals make in selecting the transportation modes that are used for particular types of trips. Typically, the goal is to predict the share or absolute number of trips made by mode. An important objective in mode choice modeling is to predict the share of trips attracted to public transportation. TransCAD provides procedures for calibrating and applying mode choice models based on multinomial and nested logit models, as well as legacy methods, and may be pursued at either a disaggregate or aggregate zonal level.

Estimation of the parameters in the nested logit and multinomial logit model is performed in TransCAD by the method of maximum likelihood, which calculates the set of parameters that are "most likely" to have resulted in the choices observed in the data. There is enormous convenience in estimating and applying nested logit models in the same software environment.

A special interface lets you draw the structure of your nested logit model graphically. A companion model management window helps setup the utility functions and data sources. With this interface, estimating nested logit models has never been easier. TransCAD supports choice set variation in both estimation and model application which is important for accurate model specification.

TransCAD incorporates several breakthroughs in traffic assignment methodology that facilitate more accurate analyses of road traffic and the impacts of transportation improvements. All of the user equilibrium methods can achieve very high levels of convergence and do so with unprecedented fast computing times. Also, most of the methods take advantage of multi-threading to run much faster on multi-core and multi-CPU computers.

Multi-Modal, Multi Class Assignment Among the advanced methods is a very flexible, master multi-modal, multi-class equilibrium or stochastic equilibrium assignment model that accommodates realistic multi-class entrance to exit tolls in addition to traditional link tolls.

This is a generalized cost assignment that uses class specific values of time and network use restrictions. A wide array of volume-delay functions have been pre-programmed and there is provision for user written functions as well. These are very convenient to use as no data transfer is required. Origin User Equilibrium Origin user equilibrium OUE can achieve much higher levels of convergence in less computing time than traditional assignment algorithms.

Also select link analysis can be performed without having to rerun the assignment. OUE supports all of the features of the multi-modal, class toll road assignment method.

Equilibrium Assignment with Volume Dependent Turning Delays For more realistic treatment of networks with traffic signals, TransCAD has a traffic assignment with HCM delay models for both signalized and unsignalized intersections so that mixed networks can be modeled. Dynamic Equilibrium Traffic Assignment Standard traffic assignment models treat both the O-D demand and network capacity as fixed and unvarying over a given time period.

These models also assume that all trips in the O-D matrix are completed within the same time period. In reality, the temporal distribution of demand over the period can vary greatly, leading to various levels of flow and congestion. In addition, some O-D trips are longer than the assignment time period, leading to potentially misleading results.

The TransCAD Dynamic Traffic Assignment DTA model addresses these problems by dividing up O-D departures by time period, assigning O-D trips by time period, and effectively managing the interaction of trips introduced to the network at differing time periods.

The flow and congestion results are often more realistic than the standard traffic assignment models, and capture the temporal distribution of congestion on the network more effectively. There is also an option to modify the capacity of one or more links to capture the effects of incidents and work zones. This DTA for planners can run on very large networks, includes calculation of spillback queue delay, and can generated congested skims that vary by departure time for time of day and activity models.

It has important applications in evacuation planning and in preparing trip tables for traffic simulation.

Screenline Analysis: Screenline analysis compares the results of trip assignment with the traffic counts on roads. More precisely, it is a process of comparing the directional sum of ground count traffic volumes across a screenline or a cordon line with the directional sum of the assigned traffic volumes across the same screenline or cordon line.

Screenline analysis is a useful tool for the calibration of trip assignment models, and it can also be used for more general purposes of calculating flows that cross a screenline. Subarea Focusing: While forecasting transportation demand for a region, you may be interested in performing a more detailed investigation of traffic patterns within a subarea, such as the downtown area.

The reduced O-D table may be used for performing a traffic assignment on a subarea network which may be more detailed than the regional network, or used in a traffic simulation for the subarea.

Assignment Differences: You can compare two flow tables to find assignment differences. The assignment differences utility creates a theme that graphically illustrates the locations and magnitudes of differences.

This tool is particularly useful for analyzing the effects of changing network attributes, such as capacity or VDF parameters, or employing different assignment techniques. You can also create an assignment table that contains the component of flow on links that pass through a specified set of links or zones.

Public transit is a specialty of TransCAD, with capabilities that greatly exceed those of other planning packages. TransCAD has special data structures for handling transit routes in all their natural complexity. Routes may be stored, displayed, edited, and analyzed.

An important feature is that transit routes can be directly placed on the streets so that interactions between autos and transit can be treated explicitly.

Moreover, stops need not be located at street intersections, but instead can be located where they really are and on the correct side of the street. Special visualization capabilities for transit make it easy to display and label overlapping routes. There is an effective interactive route editor that makes it straightforward to enter new routes and modify existing ones. TransCAD has the broadest set of transit pathfinding routines of any package and includes the methods found in other packages.

The latest version has a new, generalized pathfinder that computes composite characteristics for overlapping transit routes. There is also the broadest set of transit assignment methods including some innovative methods not found in other packages. TransCAD has special tools and procedures for creating and working with transit networks. Transit fares can be specified as flat, zonal, or mixed.

Using transit networks and fare structures, you can solve shortest path problems, calculate transit path attributes i. TransCAD can process schedules and assist in developing network attributes such as route headways. TransCAD includes the most realistic and flexible transit pathfinding and skimming methods. The key methods provide the multiple paths that travelers will use and give the analyst fine control over access, egress, and transfer properties. Transit assignment models are used to estimate the number of passengers that utilize segments in a transit network as a function of transit level of service.

These models take as input a matrix of passenger flows between origins and destinations and a transit network, and produce link level and aggregate ridership statistics. TransCAD includes an array of sophisticated transit network assignment procedures. These procedures include methods that are sensitive to fares and park and ride access, as well as equilibrium assignments, which take account of the capacity of transit service and the effect of ridership on crowding, comfort, and, optionally through dwell time effects, on the travel time on the route.

These methods distribute the flow between a particular origin and destination to multiple paths, based on their relative attractiveness. The transit assignment procedures produce a table of ridership at every stop along each route in the transit network.
