Metro count results for 3400 Block of E. Broad St.
Issue: What is the extent of speeding and traffic volume on E. Broad Street in the 3400 block corridor?
Discussion: An analysis of traffic patterns on E. Broad Street was conducted over a period of time spanning 7 days from March 18, 2013 through March 25, 2013. The site is a two way, marked residential roadway geographically running East and West. Land usage is residential. The posted speed limit is 25 mph.
An extrapolated average of 2,868.6 vehicles per day (119.4 vehicles per hour) traveled through the survey site on weekdays (0000-2359 Mon-Fri). On weekends, an average of 2,277 vehicles per day (94.9 vehicles per hour) traveled through the survey site (0000-2359 Sat-Sun).
The following groups comprise the total 18,882 vehicles surveyed:
|Class||Total Number||Percentage (% Rounded)|
|Multi Axle Trucks/Buses/Other||675||3.5%|
Weekday Peak Average Traffic Volume
|AM 0800-0900||228.2 vehicles per peak hour|
|PM 1700-1800||262.4 vehicles per peak hour|
Weekend Peak Average Traffic Volume
|AM 1100-1200||161 vehicles per peak hour|
|PM 1200-1300||209.5 vehicles per peak hour|
Posted Speed Limit= 25 mph
Maximum speed= 61.7 mph
Minimum Speed= 5.1 mph
Mean Speed= 26 mph
85% Speed= 31.1 mph
95% Speed= 34 mph
Of all surveyed vehicles 3.1% or 584 vehicles were traveling between 35-40 mph, and 0.3% or 49 vehicles were in excess of 40 mph. Peak traffic volumes exceed 100 vehicles per hour, the threshold where citizens become upset at high traffic volume. Violations by time of day indicate the greatest number of violations between 0700-0800 and between 1500-1600.
Of all vehicles traveling along this road, 96.4% are within 10 mph of the posted speed limit. Statistically, an officer would have to wait just under 3 minutes to observe a violation exceeding the speed limit by 10 mph. Using the same statistical analysis; an officer would have to wait approximately 30 minutes to observe a violation exceeding the speed limit by 15 mph. Comparing traffic volume with speed violations by time of day shows that when volume is highest, violations maintain steady throughout the day. Speed violations percentages began to increase prior to daytime peak traffic from 0500-0800 compared with the traffic volume during those same times.
