Na podstawie badań 10-ciu stacji metra w Singapurze omówiono zagadnienie dojść pieszych do przystanków komunikacji zbiorowej. Zaprezentowano nowa metodę oceny dostępności pieszej obszaru obsługi stacji metra przy pomocy wskaźnika dostępności pieszej WAI.

The problem of walking accessibility to public transport stops is presented based on author’s study of 10 mass rapid transit (MRT) stations in Singapore. The study involved interviewing passengers and field surveys of 180 walking routes within 1.2 km radius from the stations. Walking share of MRT access trips ranged from 39% to 94%, with the mean value of 60%. The average walking distances were: 613 m to MRT stations, 227 m to LRT and 193 m to bus stops. A sub-modal split model was estimated to investigate factors affecting passenger's choice of walking or taking a feeder service to access an MRT station. Besides the actual distance, factors which significantly affected the access mode choice were: number of road crossings, traffic conflicts and number of ascending steps. Based on the model coefficients, the „equivalent walking distance" equation is proposed which reflects the relative effect of these factors on the generalized walking effort. As equivalent walking distance represents the extra effort required to overcome obstacles, it can be used as an indicator of the quality of pedestrian facilities. The following equivalency coefficients were obtained: one street crossing is equal to 43 m of walking, one ascending step corresponds to 2.7 m of level walking and one traffic conflict is 26 m of walking. A new method of assessing walking accessibility of a station catchment area is proposed: walking accessibility index WAI is defined as the ratio of the actual „walking potential” of the area to the „maximum walking potential”, obtained assuming ideal walking conditions. For the stations studied, the WAI index ranged from 44% to 65%.(original abstract)
