Great to hear about your interest in pgRouting. You are most welcome to share and discuss your idea with us. It would be nice if you can document your work on "Fastest-cum-shortest route between two nodes" in a google doc and share it with us. This way we all can understand your idea and also give a feedback collectively.
I am a fourth year integrated dual degree(BTech+MTech) student from IIT(BHU) pursuing Mathematics and Computing. I am quite interested in working with the pgRouting organization(OSGeo).
Earlier I had been doing my Btech project on graph theory titled "Graph theoretical modeling of Institution campus". Under one subtopic of this project, I worked on "Fastest-cum-shortest route between two nodes" which involves relative travel time at road segments as well as turns(junctions). I find it as a more generalized version of one of last year's GSoC project "Turn Restricted Shortest path algorithm" mentored by you.
I would like to share my idea over it and your guidance would be very helpful for me. I look forward to hearing from you.
