What can you do with Emme? Here are some common applications:

Travel demand forecasting. Implement virtually any zonal-aggregate travel demand model with any feedback structure, trip generation and distribution choice models. Apply trip chaining, capture multimodal accessibility and power leading activity-based and land-use models.

Transit planning. Evaluate changes to transit routes, frequency, quality of service, transit service competition or fare integration, crowding on transit vehicles and at stations, walkability/accessibility, park-and-ride, kiss-and-ride, and transit system design.

Traffic planning. Evaluate road network expansion and management schemes, toll schemes and toll revenue forecasts, accessibility studies, junction delay, traffic demand management, critical infrastructure, freight and good movements, and bicycle traffic.

Economic, emissions and environmental analyses. Analyze vehicle cold starts, operating conditions, and other key data for emissions. Evaluate transit service quality by demographics, compare demand management techniques, perform investment-grade infrastructure and toll evaluation or forecast benefits to support cost/benefit or other project-ranking schemes.

Transportation data science.  New data sets in transportation are changing the way we develop models, interpret results and evaluate alternatives. From activity-based and other predictive models, mobility analyses or data wrangling, Emme includes some of the best data tools available and a unique environment for integrated transport modelling and Python data science.

Key benefits of Emme 4

A better way to model

A true component-based application framework for travel demand modelling and transportation forecasting. Rapidly build and deploy complete models. Refreshing new user interfaces provide excellent usability, and transition to modern Python scripting for maximum productivity.

Smart analysis and great visuals

The quickest, most complete scenario comparisons. Compare anything, including network topologies and values, matrices or charts. Over 100 maps, charts and tables. Rich GIS Basemaps from included online services, or any existing ArcGIS raster, vector or server content.

Tech support

The industry’s best software support services—plain and simple. Talk to our users and see. Unlimited telephone hotline and email contact included.

Credibility and trust

The world’s most trusted algorithms and procedures, designed to work rigorously and on large models. Emme powers some of the world’s most complex transport models. Published, peer reviewed and highly regarded procedures tempered by hands-on application and modern computing.


Uncompromised access to network topologies, delay functions, transit services and access connectors means there is nothing to get between the analyst and clear interpretations of model details. Full network editing on native model representations.


Think outside the box with model procedures that are always easy to adapt to local needs. Avoid lock-in with data that can be easily exported to open formats. Play nice with Windows or Linux OS, and share licences on local networks with floating licencing.

Updating to Emme 4?

Moving to Emme 4 couldn't be easier. Whether you are updating from Emme 3, or from an older version of EMME/2, your database, worksheets, models and macros will all work. You won't need to port your model, and you can continue working like before. And when you are ready to explore new features, take a look at our highly-regarded training courses.
