Effective transport service scheduling involves minimization of transit operating cost and maximization of generated revenue while meeting the demand for such service. This paper investigates the application of Genetic Algorithm in the optimization of Jeepney services along a busy section of their transit service routes. The main objective of this study is to improve transit service operations by...
Constant increase in urban road traffic is forcing traffic authorities to confront unavoidable congestion problems these days. This creates new challenges for city planners to generate traffic routes with better designs and improve the existing roads. In order to analyze and improve traffic routes, there is a need to understand movement patterns of major vehicular traffic inside the city. Origin Destination(OD)...
Currently, traffic signals in most countries have preset time periods for the red/yellow/green signals. Different roads in a city are configured with different time periods based on type and location of roads and the peak or off-peak hours. Such preset timings are inadequate in coping with unexpected situations such as a traffic accident or other natural disasters or specific unplanned events. Because...
In this paper we present a mathematical model of a quadrocopter, together with a complete supervisor solution for path planning to cover a designated area with a quadrocopter type UAV. The supervisor is also able to optimize and recalibrate its route in the case of unexpected events during flight, such as sudden changes in wind, or someone physically altering its position in the path. Simulations...
The role of travel behavior of private cars in the vehicle routing schemes in city logistics distribution is investigated in this paper. A mixed logit model has been established to account for the influence of travel behavior to logistics distribution. A numerical study is conducted to understand the influence of the vehicle routing schemes in city logistics distribution.
The single vehicle pickup and delivery problem with time window (1-PDPTW) is an important class of vehicle routing problem. This problem aims to find a shortest route for a single vehicle to deliver objects from origin to destination, subject to load limit and time window of delivery. This study develops an ant colony optimization (ACO) method for the 1-PDPTW. Specifically, the constraints of time...
Heavily congested roads in city areas are a common problem today. Several attempts to solve this problem by improving road infrastructure or imposing restrictions on motor vehicles entering city areas are not feasible, especially in developing countries like Sri Lanka. This may be due to lack of funds to improve the infrastructure, the objections of the general public on applying restrictions on the...
This paper presents a traffic signal control method based on ??large phase?? to solve the problem of traffic signal control. And a traffic signal control method using fuzzy system and genetic algorithm (GA) for city single-intersection is studied. The results of simulation indicate that the method can improve control effect and reduce computational cost.
The optimal allocation of emergency power supplies should consider the distribution of existing distributed generators, capacity of existing emergency power suppliers in each local district utility and important customers' needs for emergency power supplies. Based on the relationship between power supply reliability and economy, the optimum model of emergency power supplies has been proposed in this...
Without persons specially assigned to manage pedestrians, pedestrians almost are reluctant to wait in developing cities, such as Xipsilaan during green phases for vehicles. Thus, some vehicles may conflict with pedestrianspsila noncompliance, and be delayed. To solve the signal optimization problem of urban traffic with pedestrianspsila noncompliance, a hybrid optimization algorithm is developed....
Through the investigation and analysis of the actual driving cycles in Changchun, Jilin Province, the design method for transient driving cycles is introduced. The consistency of two-dimension distribution of velocity and acceleration between designed driving cycles and referenced driving cycles is applied as the design objective. The satisfaction criterion model for the design of transient driving...
In urban traffic signal optimization, the length of vehicle queue, waiting for green signal, is regarded as a performance index (PI). However, pedestrians are reluctant to waiting for green signal without person specially assigned to manage pedestrians in developing city, such as Xi'an. To the signal optimization problem of domestic urban traffic with pedestrians' noncompliance, a hybrid optimization...
