Benefits of coding on-ramps instead of normal links in Paramics

The ramp feature versus standard link  will depend on the situation and volumes.  If two highways merge but both have equal priority then doing it as a normal link is better.  If one is merging onto the other then the ramp feature will generally work better.

Ramps have special behavior of Reduced headways and friendly gaps.

With Standard links the cars will be more likely to force their way over (because they are already on the link and simply changing lanes). If volumes are VERY high and your ramps refuse to force merge then standard links might work better but will generally be less realist under normal flows.
