Cube Avenue

Dynamic Traffic Assignment

Schedule a demo


Cube Avenue, an extension to Cube Voyager, offers transportation professionals an innovative tool for analyzing traffic.

Dynamic Traffic Assignment (DTA) models offer a more detailed representation of the impact of travel choices and their corresponding travel flows than static models by modelling the buildup of congestion and variable departure times. By explicitly modeling time, Cube Avenue offers the ideal environment for many studies, such as comparing policies for alleviating peak period congestion or examining the effectiveness of emergency evacuation plans. Pioneering transportation professionals can use Cube Avenue to meld planning with real-time operations, examining likely impacts of operational responses before implementation.

Cube Avenue Overview

Cube Avenue blends macroscopic traffic assignment methods with traffic progression and time periods which approach those more typical of microscopic models. This mesoscopic scale makes Cube Avenue a useful tool in evaluating many common traffic problems, and can be tailored to fit the scale of each problem.

You specify the level of detail, for vehicle, time, and network inputs:

  • You can examine traffic as individual vehicles or as platoons of multiple vehicles
  • You can specify time increments in terms of minutes or hours
  • You can specify intersection characteristics, if desired

Using your inputs, Cube Avenue computes the lowest-cost path for each vehicle unit, based on its departure time, and computes interactions among vehicle units as they travel through the network.

Cube Avenue estimates travel speeds considering vehicle density on road segments during each time increment. The total journey time consists then of:

  • Link travel time
  • Junction delay
  • Queue time

Cube Avenue produces details useful for many studies and requires less-detailed inputs than Cube Dynasim, requiring data inputs comparable to a macroscopic model.

Cube Avenue Applications

Because Cube Avenue models time explicitly, you can study time-specific policies, such as variable road pricing or lane closures.

By considering new levels of detail, Cube Avenue allows you to complete new types of analyses. With Cube Avenue, you can:

  • Quantify impacts of upstream traffic congestion
  • Measure queuing at intersections and merge points in a network
  • Isolate secondary impacts from one intersection through another
  • Evaluate the benefits of ITS (intelligent transportation system) projects
  • Simulate alternative infrastructure, operational, and policy  changes to optimize emergency evacuation plans and strategies
  • Test strategies to improve arrival and departure from stadiums and other special event facilities, etc…
Cube Avenue Applications


Cube Avenue is a dynamic equilibrium assignment model, loading and tracking the movement of vehicle packets throughout the highway network. Vehicle packets can be any size - from an individual vehicle up to platoons of 20 or more vehicles.

Cube Avenue explicitly simulates traffic flow and traffic control systems, modelling traffic signals, roundabouts, stop-controlled intersections, and ramp merges. Vehicle packets move, stop, and queue through upstream roads and intersections.

Through an iterative process, Cube Avenue calculates optimal network conditions.

Typically, the model converges in several iterations, with an extremely fast process for smaller systems and quite feasible for large urban areas. Indeed, modelers have successfully applied Cube Avenue on areas with 3,000 zones and 25,000 links.

Numeric Results

Cube Avenue Max Queue by Time Slice

Cube Avenue produces performance measures for every specified time segment.

Output performance indicators include:

  • Traffic volumes on a road link
  • Total traffic in queue
  • Link operating speed and travel time
  • Link occupancy/utilization
  • Intersection LOS and operating conditions

When combined with Cube Base, Cube Avenue can help you analyze and visualize future operating conditions under various demands and road management strategies.

Outputs & Animations

Cube Avenue Animations

You can view and animate the data files creating:

  • Node/link posting
  • Multi-bandwidth display
  • Bandwidth animation
  • Packet-log animation

Moreover, you can summarize the data with the charting and table functions in Cube Reports.

Using standard Cube functions, various project analysis can be easily compared.
