2 OUTLINE Urbanisation / Intercity Passenger Travel Significance of Intercity Terminal Access Intercity Access Mode Choice Modeling Framework Study Area / Data Collection Access Mode Choice Models Conclusions 8 December 2010 NIT Warangal 2

3 Urbanisation Trends in India Urban Population % of the total population % of the 100 crores population % of the 140 crores population 70% of Urban Population in Class I cities 38% of Urban Population in 35 Metropolitan cities

4 Urbanisation Intercity Travel This steadily increasing urbanisation of towns has led to heavy movement of persons and materials not only within urban limits but also among the cities and towns at regional level. The expanding cities and the growing mobility of the population and goods have created greater demand for transportation between cities. 8 December 2010 NIT Warangal 4

7 Importance of Terminal Access The characteristics of the intercity transportation system and access/egress service directly affect mode choice decisions. The persons residing nearer to an intercity transport terminal are more likely to choose those modes operating from the terminal and persons located far away from the terminal may use other modes. The nature of the local access characteristics may be such that, for short intercity trips, the most efficient area of improvement would be local access conditions rather than intercity mode characteristics. It is also observed that the traveller is concerned with the door to door service provided by the transportation system and not just with the service on one segment of his trip. 8 December 2010 NIT Warangal 7

18 MODEL CALIBRATION Segmentation Vehicle Ownership VO=0; VO 1. Explanatory Variables Fare, Time, Waiting Time, Party Size, Vown. 8 December 2010 NIT Warangal 18

19 UTILITY EXPRESSIONS VEHICLE OWNERSHIP 1 V(City Bus) = fare coeff * city bus fare + time coeff * city bus time + waiting time coeff * city bus waiting time + party size coeff * party size + vehicle ownership coeff * vehicle ownership. V(Auto) = fare coeff * auto fare + time coeff * auto time + auto constant. V(Own Vehicle) = fare coeff * own vehicle fare + time coeff * own vehicle time + own vehicle constant. VEHICLE OWNERSHIP 0 V(City Bus) = fare coeff * city bus fare + time coeff * city bus time + waiting time coeff * city bus waiting time + party size coeff * party size V(Auto) = fare coeff * auto fare + time coeff * auto time + auto constant. 8 December 2010 NIT Warangal 19
