5 Predictor and LimA join Forces The market s most powerful and intuitive software for environmental noise calculation The Predictor-LimA Software Suite, Type 7810, is an efficient software package for environmental noise projects The suite bundles the intuitive Predictor and the powerful LimA in one, integrated, state-of-the-art package, providing the best solution for every project Together, the functionality of Predictor and the flexibility of LimA allow quick and easy environmental noise calculation and analysis» Predictor makes real-life modelling in accordance with standards quick and accurate» LimA provides the tools to do in-depth specialist work and fully integrate environmental noise calculations in other systems 5

6 Suite Overview Predictor software Fast learning curve, even for infrequent use Accurate and straightforward modeling, also for complex situations Fast calculations use of LimA calculation cores. Among the fastest on the market ( CRTN calculation core independently confirmed as the fastest) Time-saving integrated bookkeeping for model data and results Powerful result analysis and what-if scenarios LimA-link (menu option in Predictor) Predictor LimA-link LimA For advanced geometrical data manipulation using LimA macros LimA software Modular components, flexible, accurate, macro ability, workflows Integration in environmental management, traffic management and Geographical Information Systems (GIS) as noise calculation core Automated Reverse Engineering and Instant Noise Maps using measurements 6

7 Calculation Speed Comparison Independent test report (Euronoise 2006 papers) to compare software on same PC with same model for CRTN method: Up to 200 times difference in calculation speed 10 times faster than next best with same result quality Only 2 software could cope with 1km 2 model in time limit Lima and Predictor are the best (the same CRTN cores are used in both):» i.e. calculation software is not a commodity there are great differences Software A(*) B C(*) D E Calculation time/point (full calculation): s 11,2 518,4 13,3 2393,3 68,3 Optimisation time-saving: % 88% 99% 0% 94% 54% Optimsation quality reduction: db 0,35 1,09 0 0,45 1,49 Calculation time/point (optimised calculation): s 1,3 5,2 13,3 143,6 31,4 7

8 20 CNOSSOS-EU Calculation Method Matures the Harmonoise/Imagine as the Common EU Method for use as from 2017? Aims to give good results in acceptable calculation times for large models with: 1/3-octave calculations Meteorological influence Ground impedance 3 source heights for roads, 5 for rail 3D directivity source models Fresnel zones Gives more accurate results than existing methods Useful sites Imagine ( CIRCA website ( home) Hans van Leeuwen,

9 Experiences of use of New Methods Longer calculation times: à In theory, ca. 10,000 times increase à In practice today, times achieved Demands efficient calculation software Similar results can be expected when going from NMPB to CNOSSOS- EU Using annual average L den rather than a worst case L eq greatly reduces the effect of noise barriers Meteorological effects Can affect noise reduction activities Based on Nord2000 (Harmonoise equivalent) with 3 (preferably 5) reflections (required in Denmark) compared to Nordic Road 96 method Can be further optimised in software 9

10 Conclusions CNOSSOS-EU will come Strategic Mapping will become more calculation heavy Action Planning will become more useful enabling you to model the results of the desired/necessary actions but will require even bigger calculation load Predictor-LimA Type 7810 provides fast and accurate results and reduces size of the calculation centre/network, saving time and money 10
