Gold Thesis 2011: Transportation Engineering (TRE)

Proposed Scheduling Scheme of Jeepney Operations in Malate Area

by

Henry Ace Kang, Kevin Bryan Mascarina & Maria Jullen Padua

Adviser: Dr. Alexis Fillone

Abstract

Jeepneys in the Malate district, City of Manila, with trips to Makati, Paco, and Pasay were found to dispatch vehicles based from previous experience and perceived demand as bases.

The researchers hypothesize that due to the improper assessment of demand there is an oversupply of vehicles in all three routes. Furthermore, the inefficiency caused by this operation resulted to high fuel consumption and cost and oversupply of manpower. The main objective of the study is to propose a scheduling scheme that could improve the efficiency of the jeepney operation and service in the area of Malate, city of Manila. To accomplish this, the researchers evaluated the level of service (LOS), in terms of speed, headway and jeepney service cycle of operation; and its transport work efficiency in terms of seat-km offered and passenger-km utilized.

Based on the traffic conditions, the researchers identified the important variables to improve efficiency that would satisfy the demand at the maximum load section of each route while keeping in context the possibility of applying an occupancy load (level) that would be comfortable to the onboard passengers in most of the route length. Savings on man-hours of manpower (i.e. driver) and fuel cost were also estimated as a result of the efficiency in jeepney service operation.

9th National CE Education Convention - Cebu City

Terante, Fillone, Oreta & Belino

CE Faculty members, Dr. Danilo Terante, Dr. Alexis Fillone and Dr. Andres Oreta attended the 9th National Civil Engineering Education Convention with the theme, "Moving Towards an Outcomes-Based Education" held on July 14-16, 2011 at the University of San Jose - Recolletos (USJ-R), Cebu City. The convention was organized by the Association of Civil Engineering Educators of the Philippines (ACEEP). On the first day, Dr. Fillone presented the PhD Program in Civil Engineeering which will start in 2012. He also discussed the ERDT scholarship and proposals related to the PhD program like a research-based and special (summer) programs. Dr. Oreta, on the otherhand presented a paper about the Laboratory Course in Theory of Structures at DLSU where TecQuipment Structures Modules are used in class.

The second day highlighted the lecture-workshop on Outcomes-Based Education with DLSU ME part-time faculty Dr. Manuel Belino (now Dean of ME, Mapua Tech) and Dr. Oreta as resource speakers. Dr. Belino presented about the ABET Model for OBE. Dr. Oreta, on the otherhand, presented OBE concepts for writing course learning outcomes and converting syllabi to OBE-format. Dr. Terante was a facilitator in the OBE workshops.

Dr. Terante is the current president of the ACEEP and he announced that the 10th CE Education Convention will be hosted by DLSU-Manila sometime in September 2012. Incidentally, the DLSU CE Dept. will be 25 years in 2012.

Gold Thesis 2011: Structural Engg (STE)

"Gold Struct": Van, Erica & John

This year, Gold Thesis Awards will be given to outstanding thesis for each specialization in the present civil engineering curriculum. Last July 1, 2011, the awardees were announced and the group of Van Wesley Lim, Erica Uy and John Vincent Uy was selected as the awardee for the Structural Engineering Division. The group's adviser is Ms. Mary Ann Adajar. The abstract of their thesis is given below:

Shear Strength Determination under Isotropic Condition of Some Mine Tailings in the Philippines

by

Van Wesley Lim, Erica Uy and John Vincent Uy

This study aims to apply the cam clay model to predict the behavior and at the same time determine the shear strength parameters of some selected mine tailings in the Philippines namely Negros Oriental copper mine tailings, tailings from aggregate quarry in Cavite and Davao gold mine tailings. Tons of mine tailings are contained in dams which serve no purpose and could pose as threat if ever dam failures would occur and it is the interest of this paper to determine which among these three mine tailings possess strength parameters which may serve as construction materials. Three types of tiaxial tests, unconsolidated undrained test, consolidated undrained test and consolidated drained test, were conducted on the mine tailings in the determination of the shear strength parameters. The results of these tests classified tailings from aggregate quarry in Cavite as the mine tailing which has the greatest strength followed by the Davao gold mine tailings and lastly, the mine tailing which exhibited the least strength is the Negros Oriental copper mine tailings. Among the three mine tailings, the tailings from aggregate quarry in Cavite is considered to be the most suitable tailing which may be used as construction materials.
