Traffic incident analysis on urban arterials using ESE: A method for moderate length of time windowJul 03 2015Moderate length of time window can get the best accurate result in detecting the key incident time using extended spectral envelope. This paper presents a method to calculate the moderate length of time window. Two factors are mainly considered: (1) The ... More
