Un sistema anticaduta è allo studio a Basilea. La soluzione sembra semplice. I binari vengono riempiti di caocciù. La gomma è fissata alla scanalatura della rotaia e al passaggio del tram si comprime per poi riprendere volume. Altre città hanno cercato soluzioni a questo problema. Il materiale sperimentato a Zurigo nel 2013 non ha però superato i test.
A Basilea la mobilità lenta è una priorità. Se questo test sarà proficuo si proseguirà nel 2021 con la seconda fase. Il sistema verrà sottoposto alle sollecitazioni del traffico urbano. E se supererà anche questa ultima prova, toccherà poi alla politica decidere quanto investire per la sicurezza dei ciclisti.
