An android application navigation system which finds the safest route based on past vehicle collision data from Seattle GIS open data
Team Members
- Vehicle collisions
- Potential result of injury or death
- Many high-risk intersections with flawed designs
- Factor out of the traveler’s control
- Mistakes by pedestrian or driver has a higher chance of being fatal in these intersections
- Areas where flawed design could occur:
- Road width
- Speed limit
- Markings and signs
- Intersection infrastructure such as dividers and shoulders
- Navigation system which focuses on safety
- Mobile (Android) application
- Finds safest route rather than fastest
- Assigns safety weight for each route and intersection based on past collision data and factors
- Routes outputted based on travel conditions and method (e.g. vehicle, foot, bicycle)
- "Collisions" from Seattle GIS Open Data
- Dataset of collisions at each intersection in Seattle (2004-2018)
- Factors obtained from dataset
- Number of Collisions
- Weather, road, and daylight conditions – Type of collision (pedestrian/vehicle)
- Collision details (left/right turn, etc.)
- Severity of collision
- Severity code from 0-2
- Injury/death
- Data will be needed to assign safety weight to each intersection and route
- Searching and sorting algorithms for extracting data from dataset
- Searching and sorting algorithms for finding and calculating safest route
- Algorithm for calculating the weight of each intersection and route
- Balance of safety and efficiency
- Graph to produce route
- Intersections are vertex, and the roads are edges
- The safest and shortest route will plotted as polyline and polygons graph
