Computational design workflows for mobility networks and paths generation – propagation graphs/diagrams and generative design parameters

As a continuation of the series of studies on algorithmic and generative thinking in urban design and problem-solving, while narrowing down the scope of research to transportation networks as an exemplary urban system and research subject, this paper addresses the issues of computational design workflows for the defined problems of mobility networks and movement path generation, including various subcategories of operations related to them. Putting at the forefront smart and intelligent computational design methods in terms of design process organisation and guidance considering the stated problems, the paper is situated within the field of computational design process and methodology with a particular focus on propagation graphs construction and improvement of the system of computational problem-solving set of methods between the workflows input data and solution outputs. While it has been argued that tests in different software environments enable the best comparison of all outcomes and results, as well as proper tools assessment in terms of innovation and efficiency that each software brings to the design and research process, this study targets design possibilities offered by Grasshopper for Rhinoceros in order to obtain specific software-related overview and assessment before triangulating these findings with other available or conducted research results, including application of software interoperability and artificial intelligence. Both, already existing and new approaches to solutions to the defined mobility design and analysis tasks are rethought in the light of systematically ordered and explained use of available Grasshopper operations, design results emerging from the propagation of the designed workflows, and improvements of the presented workflows as original and unique imprints of the activity of designing a design process. Besides the theoretical, methodological, technical, and educational contributions, the paper pursues the transition from the theoretical and experimental environment to ...
