principles of implementation 1
Principles of Implementation-1

Construction of street improvements should be historically appropriate; while actual historic construction materials are not required, designs and methods should replicate as closely as possible the historic nature of streets in which improvements are made.

Strategies should be undertaken to encourage through-traffic to utilize perimeter routes rather than entering neighborhoods. The neighborhoods are defined as Italian Village, Victorian Village, Harrison West, Dennison Place, and Goodale Park.

Improvements and strategies for streets within the neighborhoods should reduce the combined effects of excessive speeds and <volumes of> cut-through traffic by reinforcing posted speed limits (temporary and permanent) and reinforce the usage of collector and arterial streets rather than local streets.

The OTMP should be applied uniformly throughout the neighborhoods, avoiding unintentional shifting of traffic patterns from one neighborhood to another.

Improvements and strategies should be consistently applied to give the neighborhoods a strong, collective identity. Such improvements should promote continuity between neighborhoods.

principles of implementation 2
Principles of Implementation-2

Improvements should be made to streets at key intersections and other key points of decision for motorists entering and traveling through the neighborhoods.

Improvements and strategies should have a high rate of return on investment.

Full-time, on-street parking should generally be increased and encouraged.

The OTMP should be fiscally responsible by utilizing phased implementation.

Responsibility for maintenance of improvements should be clearly defined.

The City of Columbus will construct basic improvements to the roadways that address the function of the street improvement. The neighborhoods will be responsible for providing enhanced landscaping, signage, or other architectural elements (see Exhibit 9, Steve Shinn).

Signage will be installed to discourage truck traffic cutting through the neighborhoods. This should reduce the number of trucks on neighborhood street and reduce the noise and congestion cuased by them.

task force recommendations
Task Force Recommendations

The MOA defines five recommendations the Traffic Task Force is to provide:

A list of priority streets needing immediate mitigation as a result of ongoing SSI construction activities;

A list of street intersections and methodology to evaluate traffic impacts as a result of the completion of SSI;

A plan to monitor traffic conditions and truck usage for at least five years following the opening of SSI;

A method to identify and prioritize traffic problems that are linked to SSI and

An overall traffic management plan (OTMP) using various tools and strategies.

4/22

recommendation 1 a list of priority streets needing immediate mitigation
Recommendation 1: A list of priority streets needing immediate mitigation

Refer to Exhibits 1-7, which show the overall layout and location of improvements to be made to provide immediate mitigation of traffic impacts. The exhibits are organized by anticipated year of implementation starting with 2003, with a summary of all implementation plans (as shown on Exhibit 7). A tabular listing of improvements by year is provided below. Furthermore, general commitments not specific to any year are defined below.

5/22

overall implementation commitments
Overall Implementation Commitments

The City of Columbus will provide measures to calm traffic and reduce speed limits on framework and local streets as allowed and prescribed by state and local regulations.

The City of Columbus will avoid infrastructure improvements or operational changes to traffic control devices and systems that may conflict with traffic calming and speed limit reduction goals as long as safe vehicular and pedestrian operations are maintained.

Following the completion of construction each year, the City of Columbus will monitor and conduct studies of speed, volume, and truck utilization within the neighborhoods to measure the effect of each phase of implementation.

Where feasible and following determination by a properly conducted traffic study that the posted traffic speed limit must remain higher than 25 mph and traffic volumes exceed acceptable levels (as defined in Recommendation 4), construct up to 10 medians along Neil Ave between Goodale and Eighth Ave.

Construction will proceed until all 10 medians are constructed or when the posted speed limit on Neil Avenue can be legally reduced from 35 mph permanently, and when traffic volumes are less than or equal to the acceptable levels (defined in Recommendation 4), whichever comes first.

Where feasible and following determination by a properly conducted traffic study that there is a speeding problem or that volumes exceed an acceptable level (as defined in Recommendation 4), construct up to 10 medians along Neil Ave between Goodale and Eighth Ave.

Construction will proceed until all 10 medians are constructed or when speeding problems and excessive volumes are alleviated, (defined in Recommendation 4), whichever comes first.

Re-mark and change signage on Fifth Ave. between Forsythe and the alley west of High to accommodate two through lanes and left turn storage at signalized intersections. On-street, 24 hour parking will be provided along WB Fifth Ave in this area.

Construct a median and one WB bump-out on Fifth Ave at the alley west of High St.

Construction may be divided up into seasons ending in 2009

Construction of medians will proceed until all seven medians are constructed or when the posted speed limit on Fifth Ave can be legally reduced from 35 mph permanently, and when traffic volumes are less than or equal to the acceptable levels (as defined in Recommendation 4), whichever comes first.

recommendation 4 a method to identify and prioritize traffic problems that are linked to ssi
Recommendation 4: A method to identify and prioritize traffic problems that are linked to SSI

Following completion of a scheduled traffic measurement conducted according to Recommendations 2 and 3, the City of Columbus will analyze the data for tends in traffic volumes, speed, accidents, and truck usage. If increases in these measurements from prior years are encountered, the locations will be further analyzed for possible problems and solutions. Reduction in the same measurements will also be noted.

Factors affecting the priority of any problem or its proposed solution include, but are not limited to accident frequency and type; percentage increases in speed, volume, and truck usage; classification of street; width of street; complexity of the solution; and cost of the solution. The City Engineer will prepare a report summarizing the analyses and possible solutions and provide it to the SSI Traffic Task Force by March 31 each year beginning in 2004.
