Le Four Power Agreement on Berlin -LRB- September 1971 -RRB- and the Transit Agreement -LRB- May 1972 -RRB- helped to slightly ease tensions over the status of West Berlin. While many restrictions remained in place, it also made it easier for West Berliners to travel to East Germany and it simplified the regulations for Germans traveling along the autobahn transit routes.
