They view speeding vehicles, cut-through traffic and associated noise and litter as detrimental to their security, property values, and the livability many have worked so hard to achieve. City staff members from Public Works, Police, and Administration work with residents to find potential answers.
At times, the answer has been "traffic calming. However, the use of traffic calming devices is used only rarely under a defined set of circumstances. Definitions "Traffic calming is the combination of mainly physical measures that reduce the negative effects of motor vehicle use, alter driver behavior and improve conditions for non-motorized street users.
Roadway or lane narrowing. Changes of roadway surface texture or color. Aesthetic improvements using landscape materials for enhanced streetscapes. Goals and Objectives The goals of traffic calming are to: Improve the quality of life within neighborhoods. Increase safety and convenience for pedestrians and bicyclists, as long as such changes do not interfere with the safe operation of intended users of the roadways. Reduce negative effects of automobile travel.
Reduce the number and severity of automobile collisions. Specific objectives of traffic calming include: Reduction in the volume of traffic traveling through residential areas.
Causing unnecessary cut-through traffic to instead use streets designated as collector or arterial streets. Promote other modes of travel walking, cycling, mass transit. That procedure is set forth below. Submitting Requests and Complaints Requests for traffic evaluation and traffic related complaints may be initiated by individual citizens, neighborhood associations, City government officials, or other groups.
Requests for traffic evaluations or complaints of chronic speeding, cut-through traffic, parking, signage, or other traffic-related problems occurring on Bloomington streets should be submitted in writing to the City of Bloomington Public Works Engineering Division using the City's form. Preliminary Review Working as a committee, city staff members review each request or complaint to determine the appropriate response. Some complaints may not rise to a level warranting remedial action. In such cases the complaining party will be notified and advised that the issue may be resubmitted in one year for further consideration.
Significant traffic issues may be resolved through increased enforcement efforts, traffic control improvements, traffic calming improvements, or a combination thereof. The person or group making the original request or complaint will be notified in writing of the action the City intends to take regarding the request.
Requests for traffic calming improvements will proceed to the evaluation phase to determine if all qualifying criteria are met. Traffic Calming Criteria Traffic calming criteria have been established by the City Administration and may be revised from time to time by City Administration. Streets that usually do not qualify for calming Physical traffic calming improvements will not be considered for any street if any of the following conditions exist: If the average violation rate VR of the statutory or posted speed limit is less than or equal to 25 percent.
If the 85th Percentile speed for the study segment is less than 5 MPH over the posted or statutory speed limit. Any of the above defined conditions can be waived by a reviewing group of staff members, and waivers will be included in documentation. Evaluation of Traffic Conditions Traffic calming requests which pass preliminary review will proceed to the evaluation phase. If the criteria are not met, these locations may be reevaluated upon request one year following the date of the data collection upon which the most recent request or complaint was rejected for traffic calming.
The evaluation phase involves the collection of data including street classification, volume, speed, traffic crash history, and other relevant information. Engineering recommends a specific traffic calming device, and a staff committee reviews the findings. Diversion Analysis If significant traffic diversion is anticipated, the staff prepares a diversion analysis. Other residents and business owners in areas adjacent to the study area may also be specifically invited.
However, voting on the proposal is limited. Traffic Calming Vote A supermajority of affected property owners is required for traffic calming installation to proceed. To be counted, mailed ballots must be returned within 14 days of the postmarked mailing date.
Device Construction When a traffic calming initiative passes, the construction phase begins. Engineering staff in the Public Works Department will finalize the design approved by the eligible voters, and add the project to the list of existing traffic calming projects Construction of traffic calming improvements will ordinarily be done in the order they are approved, absent extenuating circumstances.
The number of traffic calming projects installed each year depends on the availability of City resources. Device Maintenance and Replacement Traffic calming devices such as speed humps and traffic circles, like any other part of the road require maintenance and eventual replacement. The City has been installing and maintaining traffic calming devices since Time has shown that some traffic calming devices are easier and more cost effective to install and maintain.
Some types of traffic calming devices remain effective as a traffic calming tool while other types deteriorate, become an eye sore, and in general lose their ability to command respect and be an effective traffic calming device. The humps last as long as the wearing surface of the street they are on and have been easily replaced when the streets are resurfaced.
For this reason, the City of Bloomington reserves the right to replace other types of traffic calming devices with a speed hump when that device has completed its useful life or needs to be removed as a part of another project or for utility maintenance. Changing to a different type of Traffic Calming Device shall require the following: Written notice to affected residents living within, at most, feet of the calming device in question.
Staff will consider written responses from residents prior to making a final decision. A recommended change from the staff committee. Device Removal Process Traffic calming improvements may be removed from a street segment through a successful neighborhood petition.
The removal process may not be started until the improvements have been in place for at least a one year day period.
