Angled parking in that area with the large amount of traffic seems dangerous.
Traffic counts are currently under 40% (37.45%) of the roadway's capacity according to the latest COJ data and vehicle to vehicle accidents are not high (although vehicle to bicylce crashes are high, particularly where Prudential turns into Hendricks). There is ample evidence that supports the structural capactiy for a road diet.
That said, there are positives and negatives. Angled parking generally increases parking capacity and puts drivers exiting vehicles out of harms way of oncoming traffic.
There was a study done in Lincoln, NE which concluded that when compensatig for an increase in parking volume (meaning more cars parked on the thoroughfare... and an increase in supply will have an effect on the raw number of accidents)... there was little statistical difference between the rate of crashes for paralell versus angled parking.
The newest 'innovation' in street parking is the back in angled parking... which has shown to decrease auto accidents when compared to front in angled parking in the dozen communities that implemented this style of parking (granted, the overall sample size in the data set is still relatively low).
