The section of Bandini St. between Brockton and Palm is a cleverly devised speed trap. The direct method used to create the trap is to skew the speed data collected on the section of Bandini that includes the speed trap. Bandini is a street that harkens back to the 1920's. As such it includes 3 distinct street widths and methods of speed control in its complete length. The street can be viewed as continuing through a curve of less then 90 degrees and greater than 45 degrees, that is controlled by a stop sign. At the curve in the road Bandini changes name to Grand. The entire length can be considered to be from 1 mile to more than 2 miles depending how the traffic engineer decides to divide the street. In this case the city of Riverside has chosen to mix two street types that exist on that section named Bandini. The reason for including the extention of Bandini through the curve and into Grand will be explained. The section called Bandini has 2 distinct street widths, these are:30 ft width in the older section built before WW 2; and 36+ ft width in the section built during or after WW2. The older, 30 ft wide section of Bandini also includes "speed bumps". The full extent of Bandini is approximately 1.15 mile long broken into 2 sections of the newer 36+ wide street approximately 0.55 miles long, which is divided into two smaller sections approximately 0.275 miles long divided by a traffic control light with left turn controls at a seconday north-south street named "Palm". The older section of Bandini that is 30 ft wide and has speed bumps is approximately 0.60 mile in length. It too is divided in to multiple sections by the intersection with the main 4 lane north- south thoroughfare named "Magnolia", that bisects downtown Riverside and is the old state highway that led south to Anaheim and Santa Ana in Orange County, CA. There is one other stop sign intersection on this oldest section of Bandini. These two distinct sections of Bandini are divided from one another with a third traffic light with left turn controls at a second major north-south 4- lane road called "Brockton", that runs parallel and @ 0.25 miles west of Magnolia. In order to justify setting that section of Bandini, from Palm to Brockton, as "residential/25 mph" the traffic engineer has contrived to gang that "Speed Trap" section of Bandini that is 36+ feet wide and has no speed bumps with the older section of Bandini which is 30 ft wide with speed bumps when making his "Traffic and Engineering Survey for Speed Zoning" of that @ 0.75 mile section of older and half the newer section of Bandini. There are other problems with that specific "Traffic and Engineering Survey" that I will not go into here. A significant problem exists with regard to the remaining 36+ft wide section of Bandini from the curve where Bandini turns into "Grand" to the intersection at Palm as well. In this case the speed trap is a contrivance that the City Engineer has created for the express purpose of creating a revenue generating section of Bandini for the City of Riverside.
