Tyler was an early parliamentary candidate for the Ecology Party, in the 1976 Walsall North by-election, at a time when he was a transport lecturer at the University of Birmingham.
He became a British Rail-sponsored university lecturer and since 2000 has run a consultancy called Passenger Transport Networks.
[3] He has specialised in making the case for the importance of integrated strategic timetabling, drawing in particular on the Swiss Taktfahrplan methodology.
The Taktfahrplan is based on repeating hourly cycles where trains meet at hubs around symmetry minutes (normally xx.00 and xx.30) to optimise connections in all directions.
The 'Taktfahrplan' aims to create notions of convenience and accessibility to encourage people to use public transport.
