Abstract

The development of procedures for analyzing the economic feasibility of constructing climbing lanes on two-lane roads in Mexico and for assessing the levels of service before and after implementing these facilities is presented. Initially, the weight-horsepower ratio that is representative of the Mexican freight vehicles is obtained. Then this ratio is compared with the value reported for this parameter in the United States. From this comparison and a data set collected in a series of grades specific to Mexico, the different operating conditions of the trucks and the vehicular flows between the two countries are shown. The foregoing also shows the need to adapt to the Mexican conditions the procedure and criteria for specific grades in the 1985 Highway Capacity Manual and to generate an economic feasibility assessment procedure for climbing lanes in Mexico. These tasks are carried out by using model calibration, simulation, and regression analysis techniques. From the procedures developed, the potential use of climbing lanes in Mexico is discussed briefly. Finally, a series of conclusions and recommendations is outlined.
