A method for constructing a traffic intersection is disclosed. One version of the intersection includes a protected turn-around lane that allows traffic to turn around and proceed in the opposite direction. The protected turn-around lane provides for a protected turn without having a traffic indicator phase dedicated to protecting such a turn. Another version of the intersection includes an overpass and a protected path through the overpass allowing traffic to turn around and travel in substantially the opposite direction. Another version of the intersection includes an overpass and a protected turn-around lane.

A mixed-signal system for performing Taylor series function approximations is disclosed. The mixed-signal system includes a digital-to-analog converter (DAC), multiple resistor-to-resistor (R2R) ladders, various digital registers, a digital processor and an analog integrator. The digital processor calculates coefficients F, F, F, F, F, Fof a Taylor series equation and calculates distance functions. The digital processor also includes a digital register for storing a magnitude scaling factor &#x3c6;(x,y) of the Taylor series equation. The DAC control register uploads a lead term F(x,y) of the Taylor series equation from the digital processor to the DAC. The first-order digital registers controls resistances of the R2R ladders. The second-order digital registers uploads coefficients F, F, F, F, Fof the Taylor series equation from the digital processor to the DAC. The analog integrator adds outputs from the DAC and the R2R ladder to generate approximation results for the Taylor series equation.
