Timetable and Headway Adherence Assessment using the Gini Coefficient and the Lorenz Curve

Adherence to the schedule is of prime importance in public transport. This paper presents a specific application Gini coefficient, well known indicator economics, for headway adherence assessment. The shows that Lorenz curve, which usually used define mathematically good users' waiting time when it based on bus schedule. When computed basis ratio observed schedule, powerful visual tool can be by operators detect existence irregularities line at glance. An equation gives, an idealistic case, impact any single traffic disturbance making this coefficient comprehensive. A detailed analysis developed, proportions according level. These are obtained from new indices coming derivative curve. values these indexes alert operator disturbance. examination curve takes more time, but worthwhile, giving types indicators carried real-time data New Delhi network.
