you can have traffic warning systems like TCAS or less expensive alternatives, but in non-automated flight, they are going to be the last tool in the flight safety box. Well thought through and observed procedures go a looong way to minimizing risk. Consider also that there are still numpties flying around with their transponders switched off if there is no flight environment or regulatory requirement. Agree with earlier posters that such warning systems or lack of is not likely to be a significant contributor to this event.
