Determining the Relation between Fire Engine Travel Times and Travel Distances in New York City
A simple physical model of the way fire engines travel leads to the hypothesis that T, the average fire engine travel time, depends on D, the distance travelled according to T(D) = 2(D/a)'12 if D ? d and T(D)=v,/a+D/v, if D>d. The parameter a can be interpreted as an acceleration and v, as a cruising velocity. A field experiment was run, and the above model validated and the parameters estimate...
متن کاملA Random Walk with Exponential Travel Times
Consider the random walk among N places with N(N - 1)/2 transports. We attach an exponential random variable Xij to each transport between places Pi and Pj and take these random variables mutually independent. If transports are possible or impossible independently with probability p and 1-p, respectively, then we give a lower bound for the distribution function of the smallest path at point log...
متن کاملTravel Times of Longitudinal Waves From Surface Foci.
Tables and graphs for travel times of seismic waves propagated through the earth are based on earthquake records. This requires accurate knowledge of the longitude and latitude of the corresponding epicenters, focal depths, and origin times. It is highly desirable to compare the resulting travel time curves and tables with results derived from experiments in which all four fundamental quantitie...
متن کاملPKP travel times at near antipodal distances: implications for inner core anisotropy and lowermost mantle structure
Previous studies from PKP(AB^DF) differential travel times at large distances suggest that the central part of the inner core is very anisotropic. These differential times, however, can be affected greatly by strong heterogeneity in the lowermost mantle. Here we examine a unique data set of PKP travel times from global digital and analog stations at near antipodal distances, where the effects o...
متن کاملReal-time Estimation of Travel times on Arterial Roads – the Arrb Travel Time Model
Provision of travel time has been identified as a key road user support service which assists road authorities to improve network operation strategies and implement control measures. Travel times are commonly estimated for freeways where they are displayed to road users via variable message signs (VMS) but have proved far more difficult to calculate for arterial roads where traffic flow is inte...
