a 1-to-1 junction with buffer. We present an existence result in the free flow
case as well as a numerical method to approximate weak solutions in the general
case. In addition, we show a maximum principle which is uniform in the
non-local interaction range. Further, we exploit the limit models as the
support of the kernel tends to zero and to infinity. We compare them with other
already existing models for traffic and production flow and present numerical
examples.
