  1. 1. Estimation of severe crash frequency using two surrogates

    University essay from Lunds universitet/Matematisk statistik

    Author : Zhankun Chen; [2022]
    Keywords : Multivariate Extreme Value distributions; Copula; Extreme Value Theory; Crash frequency; Surrogate Meausre of Safety; Road safety; Mathematics and Statistics;

    Abstract : This thesis is concerned with the estimation of crash frequency based on the bivariate modeling of surrogate measures of safety (SMoS), which serve as indicators for traffic risk. Using the SMoS, any traffic conflict between two road users can be described by their proximity together with their hypothetical consequence. READ MORE

  3. 2. Market Microstructure Invariance, Bid-Ask Spreads and Impact Costs in the Swedish Stock Market : A Transaction Cost Analysis for Intraday Trading in Swedish Stocks
