Area-based Models of New Highway Route Growth
Empirical data and statistical models are used to answer the question of where the new highway routes are most likely to be located. High-quality land-use, population distribution and highway network GIS data for the Twin Cities Metropolitan Area from 1958 to 1990 are developed for this study. The highway system is classified into three levels, Interstate highways, divided highways, and seconda...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولA Stable Route and the Remaining Time Prediction to Send a Data Packet in Highway Environment
There are numerous research challenges to develop safety or non-safety applications in vehicular ad hoc networks (VANETs). One of the critical issues consists in designing a scheme that solves the local maximum problem, reduces contention phase, increases the route lifetime and reduces the frequent path disruptions caused by high mobility of vehicles. Existing schemes do not take into considera...
متن کاملA New Route to Increasing Economic Growth: Reducing Highway Congestion with Autonomous Vehicles
This paper argues that California’s self-help county tax legislation, which funds additional highway spending, amounts to a natural experiment that can be used to construct a valid instrument to determine highway congestion’s causal effect on the growth rates of GDP, employment, wages, and commodity freight flows for California counties. Our estimation results indicate that highway congestion h...
متن کاملLUNT AND WILSON: NEW DATA SETS AND HIGHWAY TRAFFIC MODELS New Data Sets and Improved Models of Highway Traffic
In this paper we report progress on the use of novel data sets to calibrate and improve car-following models of highway traffic. These models describe vehicles as discrete entities moving in continuous time and space, and use plausible behavioural assumptions to derive systems of differential equations which must be solved for vehicles’ trajectories. To date, there has been little or no systema...
