Case Studies

Toronto: the Simulation Framework

The pioneering SimFrame is a multipurpose, multilayer traffic simulation framework for the freeway and major arterial road network in the Greater Toronto Area (GTA). The model is to become MTO Central Region’s primary tool for future traffic analysis as part of planning and design, operational reviews and traffic management strategy decision-making.

Hong Kong: Vehicle and pedestrian integration in the Admiralty model

In preparation for major new infrastructure developments in Hong Kong's CBD, the Transport Department of the Government of the Hong Kong Special Administrative Region commissioned Arup to conduct a large-scale assessment of the the impact of the revamp on the local traffic. Arup's proposed layout aims to reduce congestion by diverting road-based traffic to rail-based public transport.

Rio de Janeiro: Olympic Family Project

Modelle (TECTRAN Group) is using Aimsun software in a series of ongoing deployment studies as part of the Transport Strategic Plan for the 2016 Olympic and Paralympic Games in Rio de Janeiro. The plan includes a special lane network dedicated to the Olympic Family, prioritising participants' circulation during the event, either through segregated tracks or priority shift.

New York City: Manhattan Traffic Model

The Manhattan Traffic Model (MTM) is one of the most complex large-scale simulation models currently in existence. The MTM will permit the consistent assessment of the network-wide cumulative impact of current and future traffic management projects and provide a platform for future analyses and expansion to other boroughs and, where possible, the region.

Montreal: expand and integrate the city model

The City of Montreal wants to make a move towards a reusable, super large-scale simulation base model. The first step was to find an all-in-one, extensible modelling environment that would not only allow it to streamline its simulation platform but also vastly expand the Montreal model....

Saint Petersburg: integration of Aimsun microsimulation and SPEKTR controllers

The Program Interface Controller (PIC) exemplifies what Aimsun is all about: openness and accessibility. Developed by Russian company RIPAS, the PIC is a kind of visionary tool that links Aimsun modelling software with the SPEKTR road traffic controller and the ITS SPEKTR (the control centre). This integration clearly demonstrates future possibilities to traffic engineers and potential investors and developers.

Sheffield: city centre model

Arup have been developing the Aimsun Next model of Sheffield city centre for Sheffield City Council over a number of years. It was originally intended to test the impact of a major development proposal but has subsequently been greatly expanded and developed in order to model the effects of public transport proposals and develop new transport models.

Paris: east extension of the Tramway des Maréchaux

La Marie de Paris (Paris city council) commissioned Aimsun to assess the impact of different designs for the new segregated tramway. Urban planners submitted four different scenarios: one axial tramway and three lateral tramways in different configurations.

Zaragoza: Mobility Plan

Evaluation of the short and long-term impact of a new tramway on the city's road network. The Aimsun team used an iterative macro/micro approach to study the future effects of the tramway and the results were central in Zaragoza's decision to give the project the green light.
