Model Selection After determining the possible variables and its relation to speed, we select MODEL 1 as our final model. Ws = *Lc *ki *kj This model has the highest value of F. Even if MODEL 3 obtained the highest value of R 2, the researchers would like to emphasize that in multiple regression, the high value of F rather than R 2.

Conclusion and Recommendations

Findings There are a significant number of pedestrians who do not clearly understand the meaning conveyed by the pedestrian signalization. About 60% or 6 out of 10 pedestrians do not follow the pedestrian signals. The pedestrian speed profile in all four crosswalk is slightly lower than the recommended speed profile. The signal timing allocation in these crosswalks is not based the length of the crosswalk. Even if the crosswalk length is increased, the signal timing does not necessarily be increased. (Existing Case)

Conclusions To enumerate and identify the different variables that may affect pedestrian speed. Several factors may affect the speed of the pedestrians and the researchers came to conclusion that it is not merely by density. The dimension of the crosswalk affect the speed in terms that when the length of the crosswalk is lengthen, the tendency is to increase their speed as not to be caught up by the movement of traffic. In the course of our research, we conclude that the presented variables are not enough to explain the variation on speed.

Conclusions To formulate a model to predict the pedestrian speed in a crosswalk for any given cycle. The researchers had formulated a model to predict the pedestrian signal but due to its low coefficient of determination, the researchers conclude that the model may not predict the correct pedestrian speed located outside the study area.

Conclusions To establish an algorithm for an alternative computation of pedestrian speed. Due to the low coefficient of determination of the model, the researchers failed to present an alternative computation of pedestrian speed.

Recommendations Additional model for obstructions and wall avoidance of the microscopic pedestrian simulation model is suggested to perform a better capacity analysis. Integration of pedestrian flow in planning and design. Inclusion of pedestrians to the education system. Use of fully actuated signals for pedestrians and of countdown pedestrian timers to minimize vehicular conflicts and non compliancy.

Improvement of the automatic video data collection toward the occlusion problem is highly recommended to enhance the performance of the system for higher pedestrian traffic density. Further studies on pedestrian flow which can include: –Larger study area that can include all metro manila. –Analysis of both signalized and unsignalized crosswalks. –Analysis for both one-way and two-way pedestrian lane.

Inclusion of model variables such as: delay pedestrian generators (schools, offices, railway station, malls) pavement markings dissipation time vehicular movement and speed pedestrian interaction queuing time Pedestrian analysis using: Benefit cost cellular model Cellular automata model Magnetic force model Social Force model Queuing network model
