Abstract
The Value of Travel Time (VoT) refers to the cost of time spent on transport and forms the basis of performance evaluation of different policies and scenarios in transportation planning and engineering. It takes into account various factors like trip information, traveller information and household information. This study develops mode choice models to further estimate the value of travel time in context of Land Use (LU) pattern for different zones of National Capital Territory (NCT) of Delhi, the capital of India. The entire region of Delhi was sub-divided into 17 land-use based zones and LU data, demographic data and trip data were collected through a Revealed Preference (RP) survey. The LU intensity parameters used for study are population-density and employment density of the zones. To account for the LU diversity of each zone, mix area index was calculated to balance different complementary LUs as well as the functional relationship between trip origin zone and destination zone. Discrete mode-choice model based on mixed logistic regression were developed for zones to account for the effects of LU pattern on VoT. The VoT so estimated from the study depict fluctuating values for different travel modes in different zones with varying LU patterns. The study showed that larger tracts of land dedicated to residential LU leads to lowering value of estimated VoT. This effect is more pronounced in regions with higher population densities.
