Delivery Service Management System Using Google Maps for SMEs in Emerging Countries

This paper proposes a Delivery Service Management(DSM)system for Small and Medium Enterprises(SMEs)that own a delivery fleet of pickup trucks to manage Business-to-Business(B2B)delivery services.The proposed DSM system integrates four systems:Delivery Location Positioning(DLP),Delivery Route Planning(DRP),Arrival Time Prediction(ATP),and Communication and Data Sharing(CDS)systems.These systems are used to pinpoint the delivery locations of customers,plan the delivery route of each truck,predict arrival time(with an interval)at each delivery location,and communicate and share information among stakeholders,respectively.The DSM system deploys Google applications,a GPS tracking system,Google Map APIs,ATP algorithms(embedded in Excel Macros),Line,and Telegram as supporting tools.To improve the accuracy of the ATP system,three tech-niques are applied considering driver behaviors.The proposed DSM system has been implemented in a Thai SME.From the process perspective,the DSM system is a systematic procedure for end-to-end delivery services.It allows the interactions between planner-driver decisions and supporting tools.The supporting tools are simple,can be easily used with little training,and require low capital expenditure.The statistical analysis shows that the ATP algorithm with the three techniques provides high accuracy.Thus,the proposed DSM system is beneficial for practitioners to manage delivery services,especially for SMEs in emerging countries.

Traffic Speed Interface Development in Route Choice Decision

In this paper,a method has been developed based on historic traffic data(speed),which helps the commuters to choose routes by their intelligence knowing the traffic conditions in Google maps.Data has been collected on basis of video analysis from several segments between Tuker Bazar and Bandar Bazar route.For each of the video footage,a reference length has been recorded with measurement tape for use in video analysis.A software has been also developed based on Java language to get the traffic information from historic data,which shows the output as images consisting of traffic speed details on the available routes by giving day and time limit as inputs.The developed models provide useful insights and helpful for the policy makers that can lead to the reduction of traffic congestion and increase the scope of intelligence of the road users,at least for the underdeveloped or developing country where navigation is still unavailable.

飞行仿真系统中三维地形的仿真实现

三维地形是飞行仿真系统中的重要组成部分,机场跑道作为飞机起飞降落过程中不可或缺的部分,其真实感直接影响着飞行仿真系统中地形的真实感。为了创建包含高真实感机场跑道的三维地形,在Unity下利用FlightGear中的地形数据、机场纹理数据及Google Maps纹理数据,通过动态创建地形网格和材质的方法,结合多线程技术,实现了三维地形的并行创建。实验结果表明,提出的方法可以快速创建包含高真实感机场跑道的三维地形,可用于飞行仿真系统中三维地形的仿真实现。

基于Krpano的全景校园漫游的设计与实现

在数字校园建设和发展中,以虚拟全景校园漫游为基础的校园信息化平台能够为师生提供全新的沉浸式浏览体验,并提供更集中的信息交互功能。虚拟现实技术能够真实地再现现实环境,通过交互式操作,用户可以获得与真实环境相似的感受和体验,其中全景漫游是虚拟现实技术的一种典型应用。该文以南开大学滨海学院为实践区域,基于Krpano平台,利用Google Maps地图服务,采用全景图制作技术、SQL数据库技术和计算机网络技术搭建了一个虚拟全景校园漫游系统,并可跨系统、跨设备使用。系统实现了2D校园全景和谷歌地图信息服务功能,并提供了搭载陀螺仪传感器的可穿戴式VR设备使用的WebVR全景显示,满足了数字校园分布式、便于使用的需求。实践证明了基于Krpano框架设计能深度定制虚拟全景校园漫游系统的相关功能,能有效开发并拓展系统,并具有重要的实践意义。

Design and implementation of user information sharing system using location-based services for social network services

Internet takes a role as a place for communication between people beyond a space simply for the acquisition of information.Recently,social network service(SNS)reflecting human’s basic desire for talking and communicating with others is focused on around the world.And location-based service(LBS)is a service that provides various life conveniences like improving productivity through location information,such as GPS and WiFi.This paper suggests an application combining LBS and SNS based on Android OS.By using smart phone which is personal mobile information equipment,it combines location information with user information and SNS so that the service can be developed.It also maximizes sharing and use of information via twit based on locations of friends.This proposed system is aims for users to show online identity more actively and more conveniently.

How fast is it to city centers?The average travel speed as an indicator of road traffic accessibility potential

Transportation is the lifeblood of a modern metropolis.Accessibility generally refers to the interconnection between nodes in a regional traffic network.The purpose of the paper is to obtain more realistic and accurate measures of travel speed and to study the road traffic accessibility potential in cities.This study proposes a method for analyzing road traffic accessibility potential which is based on the average travel speed to city centers in off-peak times and which ranks 80 cities around the world.Based on the Suomi National Polar-Orbiting Partnership satellite’s visible-infrared imaging radiometer suite(NPP-VIIRS)night-time light data,urban built-up areas and city centers were extracted.Further,with the aid of the Google Maps application programming interface(API)network crawling technique,travel times and travel distances for several optimal routes to city centers by car were obtained.Feasible proposals for improving road traffic accessibility and planning urban transportation in different cities are presented.The proposed method offers a new possibility of analyzing traffic accessibility using internet data and geo-spatial methods.
