The project aims to implement a new function called "pgr_dijkstraDD" that replaces the existing "pgr_drivingDistance" function. The new function will have all overloads, including single and multiple vertices as before. The function will return columns such as sequence, depth, start vertex ID, node, edge, cost, and aggregate cost for all overloads. The project will also include testing of the new function with pgTap Tests. Documentation for the new function and migration guides for users to switch to the new function will also be created.
