VICE RELIABILITY has improved on London sport's E3 route in Ealing result of a bus demonion project carried out by )epartment of the Environ:. After the implementation the team's recommendis there was an appreciable ction in the number of s that took longer than 65 ites (ie eight minutes er than scheduled) to )lete the full journey. The anger waiting time how was not significantly red.
le project is descri')ed in Tort Bus Demonstration ,?et; Summary Report No 7, E3 Route, just published he DoE.
le purpose of the scheme to find what improvement aus operation could be .ved by introducing parkrestrictions along the E3 route where congestion causing delays and fatigue us drivers.
: points where parking rols already existed rcement was increased. roadway at two junctions was widened so that buses could turn more easily. The project was designed also to test whether it was possible to predict the improvement in service using computer simulation.
In order to achieve the improved reliability of the bus service parking restrictions were applied along about half of the 91/2-mile route. The cost of this enforcement was about C15,500 per annum, but much of this would have been required anyway.
Bus " cages " at bus stops, ie, marking out a rectangular stopping space, were very effective in preventing parking at bus stops. The report also states that it was possible to improve bus reliability significantly by tackling the problem of delays on the approach to junctions with major roads.
The experience gained in using the computer simulation model of the bus route found that the present programme could only predict the effect of major changes, such as the withdrawal or breakdown of a bus.
