Myway or the Highway!

We aim to facilitate the interaction between different scales of movement (walkers / drivers) in proximity to causes of environmental destruction within the city. By using I 690 as a focus, interventions will counteract and increase awareness of these environmental factors.

GIS has become a way for us to identify both location and potential program for interventions along I 690. These interventions could take many forms relating to car users, walkers, or both simultaneously. By taking a series of TINs from multiple features (streets crossing I 690, vacancies, parks, and recreation within 500 feet of pollution sources), we are employing previous techniques of surface and solid analysis to apply these abstract TINs back to the city.

Surface analysis extracts high points of car users and walkers as well as mid ranges where there are more even distributions; these will be future sites of intervention which either cater to walkers, drivers, or establish points of interaction between the two scales of movement.

Solid analysis extablishes areas of difference or similarity between the two user groups by extruding a solid between TINs of different heights. This will also identify areas of either autonomy or interaction between the walkers and drivers. By also splitting this solid according to parcels and overlaying with vacancy data, we can narrow our focus back to the original source features.
