Scheduling Recovery — High-Frequency Urban Route
Timetable revision and schedule recovery for a high-frequency urban route where running time drift had rendered the timetable inoperable — running time surveys, timetable rebuild, and vehicle schedule restructure.

Engagement Detail
In detail.
A high-frequency urban bus route had been operating against a timetable that was three years out of date. Running times set at launch had never been revised despite significant changes to traffic patterns along the corridor. By the time E2Gx Mobility was engaged, the achievable running time exceeded the scheduled running time by an average of 14 minutes in the peak period — meaning every departure was structurally late by design.
The intervention began with a six-week running time survey programme covering all time periods in both directions. Survey data confirmed running time variance of up to 22 minutes between off-peak and peak periods — variance the existing timetable had not accounted for at all. The timetable rebuild stratified the route into four time bands with distinct running times, layover allocations, and departure headways.
The vehicle schedule was rebuilt from the revised timetable, reducing the fleet requirement by three vehicles while maintaining the same scheduled frequency. At 60 days post-implementation, on-time performance had recovered from 38% to 79% — and the route's operating cost per kilometre had fallen due to the fleet reduction.
