Security through mobility, not just in mobility

Link: https://safe-yelli.github.io/security-through-mobility/

Context

• Women face a lot of issues with accessibility through the lens of safety on roads. ¹
  • SafeYelli ² has been documenting it for over a year. So have SafeCity ³, SafetyPin ⁴ and other solutions
• Safety and access to public spaces in the city are negotiated for accessibility to the self by women ⁵

Motivations to design with

• Crime Prevention Through Environment Design (CPTED) is something that can be used to redesign bustands as safety islands as opposed to the City's initative to build safety islands ⁶
• Constant life and movement should be encouraged by mixed activites. Bus Stands in India are already full of mixed activites, but can it be formally encouraged? ⁷
• Feeder busses would encourage constant activity. [Need Citation]
• A data visualisation to realise the areas that are not covered by existing bus routes and would be helped by feeder busses. A system? could be created.
• What new methods exist to understanding a complex routing system? Through SFNetworks and STPlanner packages for R.

Problem statement

• Smaller or no Bus travel roads need to have busses running through them. Like on the inner roads of Ylk New Town.
• What are these roads that the BMTC needs to run new routes on?
  • Are they based on population density?
  • Are they based on the number of workplaces nearby?
  • Are there a lot of long distance travellers? Do migrants stay in housing that is far away?
  • Are these roads deserted after a certain time?

Avant-garde routing

• What if i ignore residential zoning and route public transport through them.
• Would this not reduce private vehicle traffic possibly?

Analysing the network

Algorithm as i see it

• Load both layers (Bus routes and existing network)
• Find intersecting roads or roads that satisfy a filter within a radius
  • Filter out roads that do not have a bus route
    • Filter/Weight based on population, school density, work-place density, etc

Learning history

• Multiple CRS issues the busRoutes and RoadNetwork data come from different sources
• Both networks are not fully alike and hence the network cannot be analysed without fully snapping both networks together.
  • I attempted to round the data to achieve this, but this does not fully work.
  • I need to snap with the sf library's method, did not work and could not fully implement in the given time
  • The edge query functions need to be fully explored

To be done

• Implement multiple other filters as suggested previously
• Simplify and round both networks
• Verify idea with professionals
