1. Discipline among drivers
2. Poor road condition
3. Improper road assignment (gaya ng bus stops, u-turn slots)
4. Establishments that cause heavy traffic
5. Too much vehicles on the road

These problems should be addressed. Giving criminal charges sa mga nagca-cause ng traffic, for me, is a corrective action lang, and I agree with this. Pero what we need ay yun long term solution to solve the heavy traffic.
