What dynalogic does

Dynalogic SARL is a Paris-based mobility and traffic engineering consultancy founded in 1994 by Philippe Mattera. The firm provides traffic modeling, mobility planning, road and urban infrastructure design, intersection and roundabout engineering, parking studies, pedestrian displacement simulation, and logistics and transport studies for government entities (municipalities, departments, regions, transport authorities, urban communities) and private-sector clients (real estate developers, retail operators, highway concessionaires). Service offerings are organized around five core domains: traffic modeling (macroscopic road models and multimodal urban models, circulation plans), road and urban infrastructure (interchanges, public transport lines, activity zones), intersection and roundabout design (signalized intersections, roundabouts), parking studies (accessibility, design, CDAC/CNAC regulatory dossiers, urban parking management), and pedestrian displacement studies (multimodal hubs, stations, stadiums). The firm also serves logistics, rail, and waterway sectors and has developed a new mobility services design practice backed by its wholly-owned spin-off Dynasyndic. Named clients include RATP, Société du Grand Paris, Mairie de Paris, VINCI Autoroutes, Carrefour, Leclerc, Altarea Cogedim, and Bouygues Immobilier, with project footprint covering metropolitan France and overseas departments (Martinique, Reunion).

The firm delivers studies using a mix of proprietary and licensed modeling tools: DYNASIM for dynamic traffic simulation, GIRABASE for roundabout capacity, alongside CUBE, TRANSCAD, QGIS, AutoCAD, COVADIS, and 3DS MAX. It also operates proprietary intelligent directional counting cameras developed in-house by an R&D team member, and runs Dynasyndic as a spin-off serving as delegated mobility project owner for urban operators. Technology differentiation is grounded in multimodal expertise (combining vehicles, public transit, bicycles, and pedestrians), dynamic simulation as decision-support, and an in-house measurement stack.

The business operates as a project-based professional services firm. Engagements are quoted per scope and typically structured as multi-year contracts, won through direct business development, tender responses, and the firm's 30-year reputation and 800+ study portfolio. The current team comprises six members (founder plus project managers and study engineers, mostly graduates of French elite engineering schools including Centrale Lyon, Supméca Paris, Centrale Marseille, Institut d'Urbanisme de Paris, and École des Ponts ParisTech). The company is privately held with no external investors, no parent company, and no disclosed funding rounds.

Core offering

Dynalogic SARL is a Paris-based mobility and traffic engineering consultancy providing project-based studies in traffic modeling, road and urban infrastructure design, intersection and roundabout dimensioning, parking studies, pedestrian displacement simulation, logistics and multimodal transport, and the design of new mobility services. The firm delivers consulting engagements to government entities, transport operators, real estate developers, and commercial enterprises across France using proprietary dynamic simulation tools (DYNASIM, GIRABASE) and a portfolio of 800+ studies over nearly 30 years.

Product overview

Dynalogic is a mobility and traffic engineering consulting firm offering a portfolio of interrelated consulting services organized around five core domains: traffic modeling (macroscopic road and multimodal urban models, circulation plans), road and urban infrastructure (interchanges, public transport lines, activity zones), intersection and roundabout design (signalized intersections, roundabouts), parking studies (accessibility, design, regulatory dossiers, urban parking management), and pedestrian displacement studies (multimodal hubs, stations, stadiums). The firm also serves logistics, rail, and waterway sectors, and has developed a new mobility services design practice backed by its spin-off Dynasyndic. Specialized software tools — DYNASIM for dynamic simulation and GIRABASE for roundabout capacity — are used internally across engagements to power analysis and validation.
