Abstract

Highlights: Traffic corridor (highway vs. transit) for travelers with/without cars is studied. Critical values of transit capacity are derived for a bi-modal traffic corridor. Highway and transit mode can be both complementary and substituting. Jevon's paradox exists when transport technology improvement is considered. Abstract: This paper considers a bi-modal traffic corridor with a highway and a transit line where car-available-travelers tend to be more sensitive to crowding than car-unavailable-travelers in transit vehicles. Modal spilt and departure time choices of heterogeneous travelers (car-available- and car-unavailable-travelers) are considered. Two capacity design problems, namely total travel cost minimization with budget constraint and total system cost minimization with budget and equity constraints, are studied. It was found that when there is a construction/operational technology improvement for one traffic mode, the cost for its unit capacity reduces and its optimal total investment may increase (i.e. Jevons paradox).
