Microsimulation
Microsimulation (from microanalytic simulation or microscopic simulation) is a category of computerized analytical tools that perform highly detailed analysis of activities such as highway traffic flowing through an intersection, financial transactions, or pathogens spreading disease through a population. Microsimulation is often used to evaluate the effects of proposed interventions before they are implemented in the real world. For example, a traffic microsimulation model could be used to evaluate the effectiveness of lengthening a turn lane at an intersection, and thus help decide whether it is worth spending money on actually lengthening the lane. Introduction Microsimulation can be distinguished from other types of computer modeling in looking at the interaction of individual ''units'' such as people or vehicles. Each unit is treated as an autonomous entity and the interaction of the units is allowed vary depending on stochastic (randomized) parameters. These parameters are ...

Quadstone Paramics
Paramics is traffic microsimulation software, originally developed by Quadstone Ltd. There is a related pedestrian microsimulation product called the Urban Analytics Framework. Background The Paramics project was originally established in the early 1990s by the UK Department for Transport and was further developed as a project by the Edinburgh Parallel Computing Centre, based at the University of Edinburgh. By the mid 1990s, some of the project staff left to form Quadstone Limited. A partnership was formed between Quadstone Limited and SIAS but was quickly dissolved in 1998 as both parties could not agree on the direction of the partnership. In 2005, Quadstone was acquired by Portrait Software. Today, Quadstone Paramics operates as an autonomous division within Pitney Bowes Business Insight. The software evolved into Paramics Discovery which is now managed by Systra. Concept Paramics was created from scratch based on several models and mainly on the paper “A model for t ...

Euromod
EUROMOD is an EU-wide tax-benefit model originally maintained, developed and managed by the Institute for Social and Economic Research at the University of Essex. Since 2021 EUROMOD is maintained, developed and managed by the Joint Research Centre of the European Commission, in collaboration with Eurostat and national teams from the EU countries. It belongs to the class of static microsimulation models and has modules for all 27 EU member states (and the UK until 2021). What is EUROMOD EUROMOD allows researchers and analysts to simulate, evaluate and compare the impact of tax-benefit policies in terms of households' disposable, as well as computing poverty, inequality and budgetary indicators. The model can be used for analysing the effects of already existing policies and to evaluate tax-benefit policy reforms. The model also offers extended functionalities that allow the user, among other features, to compute marginal tax rates and net replacement rates (as indicators of wo ...

Dynamic Microsimulation Pension Model
A dynamic microsimulation pension model is a type of a pension model projecting a pension system by means of a microsimulation and generating the complete history of each individual in a data set. The results of such model offer both the aggregate (e.g. total replacement ratio, implicit debt) and individual indicators (e.g. individual cash-flows) of the pension system. Thanks to complexity of results, there is a possibility to investigate the distribution of pensions, poverty of pensioners, impact of the changes of the pension formula, for more examples see e.g. (Deloitte, 2011). Detailed individual set of (administrative) data should serve as a model input. Dynamic Microsimulation Pension Models A dynamic microsimulation pension models (or a dynamic model with dynamic ageing) is a type of a pension model – see its taxonomy and also (Gál, Horváth, Orbán, & Dekkers, 2009) . There are two basic types of this kind of model - (i) deterministic, which is based on best estimat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TransModeler
TransModeler is the name of a based traffic simulation platform for doing wide-area traffic planning, traffic management, and emergency evacuation studies that is developed by Caliper Corporation. It can animate the behavior of multi-modal traffic systems to show the flow of vehicles, the operation of traffic signals, and the overall performance of the transportation network. About TransModeler TransModeler is a traffic simulation package applicable to a wide array of traffic planning and modeling tasks. TransModeler can simulate many kinds of road networks, including freeways and downtown areas, and can analyze wide-area multimodal networks. It can be used to model and visualize the behavior of traffic systems in a 2-dimensional or 3-dimensional GIS environment to illustrate and evaluate traffic flow dynamics, traffic signal and ITS operations, connected and automated vehicles (CAVs), and overall network performance. Like other Caliper Corporation products, TransModeler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PTV VISSIM
PTV Vissim is a microscopic multi-modal traffic flow simulation software package developed by PTV Planung Transport Verkehr AG in Karlsruhe, Germany. The name is derived from "Verkehr In Städten - SIMulationsmodell" (German for "Traffic in cities - simulation model"). PTV Vissim was first developed in 1992 and is today a global market leader. Scope of application The scope of application ranges from various issues of traffic engineering (transport engineering, transportation planning, signal timing), public transport, urban planning over fire protection (evacuation simulation) to 3d visualization (computer animation, architectural animation) for illustrative purpose and communication to the general public. PTV Vissim is part of the PTV Vision Traffic Suite which also includes PTV Visum (traffic analysis and forecasting) and PTV Vistro (signal optimisation and traffic impact).

Pensim2
Pensim2 is a dynamic microsimulation model to simulate the income of pensioners, owned by the British Department for Work and Pensions. Pensim2 is the second version of Pensim which was developed by Institute for Fiscal Studies in the 1990s. The time horizon of the model is 100 years, by which time today's school leavers will retire. Pensim2 uses a lot of external alignment figures. Overview Pensim2 uses aggregate and micro-level data from different data sources, e.g. BHPS, LLMDB and the Family Resources Survey. It simulate a very wide range of economic processes: earnings, housing, savings, pensions A pension (, from Latin ''pensiō'', "payment") is a fund into which a sum of money is added during an employee's employment years and from which payments are drawn to support the person's retirement from work in the form of periodic payments ..., taxes. It has the useful feature of allowing the user to specify certain parameters (for example the rate of return t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Traffic Flow
In mathematics and transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems. History Attempts to produce a mathematical theory of traffic flow date back to the 1920s, when Frank Knight first produced an analysis of traffic equilibrium, which was refined into Wardrop's first and second principles of equilibrium in 1952. Nonetheless, even with the advent of significant computer processing power, to date there has been no satisfactory general theory that can be consistently applied to real flow conditions. Current traffic models use a mixture of empirical and theoretical techniques. These models are then developed into traffic forecasts, and take account of ...
