The main purpose of the research is to evaluate the crest vertical curves radii Rv, not considering a conventional value of the opposing vehicle height h2, but the average vehicle heights h2(m) and the value of the 15th percentile of the height distribution h2(15) of the passenger car population. The study only considered car models with more than 20,000 registered vehicles in Italy. One hundred and fifteen car models belonging to different brands were taken into consideration, for a total of over 9 million vehicles. For the statistical sample analyzed, the following vehicle heights were estimated: h2(m) = 1.48 m and h2(15) = 1.39 m. The deviations between the crest radii calculated with the Italian standard (h2 = 1.10 m), and those obtained for h2(m) = 1.48 m and h2(15) = 1.39 m are up to 12%. The differences ΔHv between the values of the visible vehicle body height Hv = Hv(t) calculated using, respectively, h2(15) = 1.39 m and h2(m) = 1.48 m are modest. The value h2(m) = 1.48 m could be adopted in order to reduce the highways construction costs. In fact, the research shows that the value h2 = 1.10 m is too conservative and leads to oversizing of the crest vertical curves. Therefore, it would be necessary to make an appropriate choice of h2 value in order to take into account the current heights of passenger cars.

“…1 The key problem for multiple targets tracking is distinguishing between measured values resulted from a specific target and measured values caused by other radar target echoes or inference. 2 The Doppler measurements are employed in couple with the target range information as supplementary state information, which is used to overcome this problem of recognizing rangeoverlapped targets. Literature 3 puts forward an advanced joint probabilistic data association ( JPDA) scheme, which utilizes Doppler measurements along with range measurements through a nonlinear programming method.…”

Extended binary phase shift keying (EBPSK) transmit-receive system is considered as a high-resolution radar tracking system. The target kinematic states can be estimated from a time series of target range and velocity measurements. The measurements usually have a huge amount of data. In this article, we present a big databased tracking strategy comprising Doppler measurements as part of the data association procedure and evaluate the advantages of the proposed scheme. First, the principle of EBPSK transceiver is introduced. In the proposed system, range spread target can be denoted by the target impulse response. Second, we proposed an efficient big data association scheme that utilizes both target range and target velocity measurements for linear multitarget (LMs) tracking. When the target velocity measurements are not incorporated into target kinematic state estimation, the nonlinear filter bank for the combination of the component of target velocity measurements is not necessary. Finally, a great enhancement in the tracking performance of the big Doppler data association method with the LMs combined probabilistic data association scheme is demonstrated by simulation experiment.
