    Urban mobility is directly linked to the demand for communication resources and, clearly, its understanding is useful for better planning of urban and communication systems. However, getting data about urban mobility is still a challenge. In many cases, only a few companies have access to accurate and updated data. In most cases, these data are also privacy sensitive. It is thus important to generate models that can help to understand mobility patterns. We here characterize the demands of a two-way car-sharing system. We explore data of the public API of Modo, a car-sharing system that operates in Vancouver (Canada) and nearby regions. Our study uncovers patterns of users’ habits and demands in the service, which can be explored for urban and communication planning

    Usage Trend Analysis and Forecasting for Ride Sharing: A case of Bildeleringen : An empirical approach using the car-specific data

    Car-sharing is gaining a lot of popularity amongst users, as more people are finding various instances and benefits to use this service. With this development, there is increasing number of companies setting up car-sharing platforms to satisfy this growing demand. As is characteristic of highly competitive industries, the players win market share by effective planning and efficient operations. One aspect of effective planning is ensuring that the carsharing fleet of cars is suitable to the needs of the target customers. The goal of this paper is to use past data to analyse the car features that are affecting the demand of cars and propose a model to predict the future demand of cars using these features. To achieve this, we obtained the ride data from Bildeleringen, the leading car sharing operator in Bergen (Norway). We analysed all of the data tables and picked the variables that were essential to our study. After cleaning up the data, we created a new dataset that gave car level information on the car type, car features, the availability period, and the usage variable. We obtained two measures of usage from the data – time driven and kilometres driven. Based on the business model of Bildeleringen where more of the cost of usage is attributed to the driven time, we chose the time driven as the more appropriate usage measure. Also, we noticed that some cars were available on the platform for way longer than others, hence we went a step further to define the measure of usage as the kilometre driven as a ratio of the time available on the platform. Using charts, histograms, and box plots, we investigated the possible relation in the car features and the usage of these cars on first glance. We then proceeded to run a multiple linear regression on our data set. We then used 10 data prediction methods to model the car usage and tested the predictive performance of the models using cross validation. The models used belonged to the Linear regression, Ensembles, Decision tree, Bagging and Boosting. The results of the show that are the car level features that affect the demand are transmission type, wheel drive system, baby pillow availability, child seat installed, and roof box installed. Based on the Mean Squared Error comparison, we also found that the Decision tree is the best model to use for the prediction.nhhma
