Optimal Operation Solution for Public Bicycles Based on Genetic Algorithm

Aiming at the various problems with the scheduling of urban public bicycles, this paper conducted a research on the shortest path between rental points and employed the Floyd algorithm to find the optimal route. Based on the conditions of limited number of bicycle transportation vehicles and in different time slots the bicycle rental points were required to restore to the original number of bicycles, a constraint scheduling model was established according to the bicycle supply-demand relationships of the rental points, and the Genetic Algorithm (GA) was used to solve the model to find the shortest path. In terms of balancing the bicycles at each rental point, this paper re-distributed the initial bicycles according to the different demands of each rental point in different time slots, and solved the problem using the solution of the first problem to obtain the optimal vehicle route. This research is a useful reference for solving difficulties in public bicycle scheduling.

Quality of the bicycle transportation service in small and intermediate cities in Colombia

Nowadays, the bicycle, as a means of mobility, is the most eco-friendly vehicle; however, and despite its many benefits, its use at a global scale is quite low. This study aimed to discover the reasons for the low use of bicycles as means of transportation in Colombian, by formulating a method to analyze the service quality of the Bicycle Transportation System (BTS) in small and intermediate cities of the country. Measurement techniques used in the Social Sciences allowed us to study the perception that the user has of the BTS, to identify the most representative attributes of the system and their respective variables, as well as to qualify and quantify them. Applying the method to a case city allowed elucidating the deficiencies perceived by the BTS users, as well as evaluating variables quantitative and qualitatively to obtain a level of service that measures the user acceptance rate of the BTS. The results derived from this method make possible to manage operational actions that improve efficiency in bicycle mobility, with its corresponding economic, environmental and social benefits, to ultimately improve the quality of life of its users. The method and the recommended techniques can be applied to small and intermediate cities, allowing the necessary adjustments for any other type of city.
