The user interface is clunky. Like its competitors, Traffic is hindered with legacy code, features and interfaces. It often feels like they're running out of space for buttons! That being said, I think it's the best of a bad bunch! And it works!
The support portal and documentation need a complete overhaul. The Traffic support portal declined when it migrated into Deltek's portal. It now feels like you've stepped back in time!
Content needs restructuring and rewriting. It's a mess and it's hard to find what you are looking for. PDF downloads are a nightmare. Needs clean html pages.
The UI screens for resource planning (the 10,000ft view screens) are cumbersome and in need of a design overhaul. We don't use them at all, they're pretty useless. The new Work Planner looks promising, but overly complicated and hindered by the general UI weaknesses of their legacy Adobe Air App platform.
Projecting agency capacity is something we do outside of TrafficLIVE. Because we're often trying to predict against things that aren't yet jobs in the system, alongside jobs that ARE in the system. For this kind of flexible/lightweight capacity planning, we end up using another third party application. TrafficLIVE is best used when you have definitive estimates/bookings.
Integration with Merlin Project is non-existent. Mac users don't generally use MS Project, so this is a bit of a failure on Deltek's part.
Being able to assign multiple resources to one task would be a better way of structuring quotes and jobs in Traffic. It would save time. It would reduce the number of tasks needing to be created for every job. Project plans have been created this way for years, why doesn't Traffic allow this?
