Abstract

Within the frame of the Metro Development Study, a comprehensive transportation planning effort being undertaken by Attiko Metro, a multimode strategic transport model has been developed. The aim of this paper is to demonstrate the feasibility of developing primary mode choice models for different travel markets using mixed RP and SP data, determine price and service elasticities of modal demand as a decision tool to increase PT market share, and forecast the modal impacts of car access restrictions within varying cordon boundaries, due to an odd/even licence plate number scheme.

Four mode choice models developed recognise three main modes (car, taxi, PT), two (non-) car owning household types, and two (off) peak dominated home-based trip purposes. Certain (among other: nested) choice structures proved to be adequate. The relative valuations ofgeneralised cost components are based on a stated choice experiment and are scaled using revealed choices.

Concerning PT demand responsiveness of differing travel markets, fare elasticities proved to be of small magnitude (due to the current low base fare), as opposed to service elasticities, indicating a higher potential to improve PT share through increased route frequencies and priority measures.

In the forecast mode, the incremental form of the logit models has been applied. Along with network improvements including new metro lines, the net modal effects of extending the area boundaries of a 15-year old car restraint scheme are assessed.
