Tenders Are Invited For Engineering Services – Traffic Modeling Expert Services

Engineering Services – Traffic Modeling Expert Services. The Object Of The Acquisition Includes The Study Of The Traffic System, Traffic And Traffic Flow By Modeling. Different Modes Of Transport (Car Traffic, Public Transport, Bicycle Traffic, Pedestrians And Other Modes Of Movement) Are Discussed Both Separately And As A Whole. The Scope Of The Procurement Includes The Following Tasks: • Preparation Of Traffic Forecasts • Preparation Of Functionality Reviews The Scope Of The Procurement May Include Traffic And Traffic System Impact Assessment, Traffic System Level Planning, Public Transport Route Planning, Project Evaluation, Functionality Reviews, Planning And Optimization Of Traffic Light Programming For The Models, And Accessibility Assessment. The Review Area Of ​​The Assignment Can Be An Overall Review Of A City-Level Area Or A Review Of A Narrower, Limited Area. The Assignment May Include Modeling, Evaluation And Analysis Of Different Years And Alternatives. It May Also Include Developing And Calibrating The Models Used. Assignments May Involve Interaction With Participants, Workshops Or The Use Of Other Interaction Methods And Reporting Of Results. The Supplier Must Use A Traffic Modeling And/Or Functionality Review Program That Is Compatible With The Programs Used By The City Of Helsinki, Which Are: Traffic Modeling Software Emme And Functionality Review Software Vissim. The Modeling Work Is Documented With Sufficient Accuracy So That The Modeling Is Repeatable And Usable For Further Reviews. At The End Of Each Job, The Prepared Models, Their Initial Data, Results And Documentation Are Handed Over To The Customer In Their Original File Formats. Any Reviews Performed With The Helmet Model Maintained By Hsl Are Documented In Accordance With The Applicable Hsl Guidelines (Https://Hsldevcom.Github.Io/Helmet-Docs/Hsl-Toiden_Dokumentointi.Html). A Document Is Produced From The Simulation Models Made, Which Records At Least: The Name Of The Simulation Model, The Version Number Of The Software With Which The Simulation Was Made (In Practice, The Version With Which The Model Was Last Saved), The Time, An Overview Of How The Model Was Built And The Modifications And Scenarios Contained In The Model, Expanded With Short Descriptions Of What Each One Mainly Contains. Matters Related To The Traffic Light Controls Presented In The Simulation (E.G. Changes Made To Existing Ones Or Completely New Ones) Are Basically Documented In Connection With The Documentation Produced From The Review (Report, Etc./Its Appendix). The Vissim Software For Functionality Checks Used By The City Of Helsinki Is Updated Several Times A Year. Basically, All New Projects Are Done With The Latest Version Of The Software. Efforts Are Made To Update Possible Old Functionality Review Models To The Latest Version Of The Software. If Updating To The Latest Version Is Not Possible, Further Processing Of The Model With An Older Version Of The Software Or A Completely New Model Produced
