Homework 13, Street Functions and Design Targets

1. (To be typed) Melnea Cass Blvd has many ideal features as an urban through-traffic street. List 4 of those features along with a one-sentence description of what’s special or critical about that feature.

2. (To be typed) For a street type called crossable collector or mixed function neighborhood street:

What is the target number of lanes, and why

What special feature should there be at unsignalized crossings and why

What is the target speed, and why

What roadway features will help it achieve its target speed?

Bikes could be served with either bike lanes or cycle tracks. Why are cycle tracks better for speed control?

3.(To be typed) For your assigned street (see below), copy / paste the 12-point outline (6 points on function, 6 points on design targets) found below and complete it. Then, for a typical section (a part of a block between intersections), sketch its current cross section, and sketch a new proposed cross section that aims to achieve your design targets. Measurements of the current situation may be approximate. Sketches may be drawn by hand or using CAD. They should be roughly to scale and should note dimensions (widths) for each cross-sectional element. Describe any traffic management, parking management, or environmental management practices that are also important to achieving your design targets.

Assigned Streets.

Last name starts A-H: Newbury Street, Back Bay (Arlington St to Mass Ave).

K-O: Mass. Ave. between Washington Street and Columbus Ave.

P-Z: Tremont Street between Melnea Cass Blvd and Mass Ave.

12-point outline for you to copy/paste:

Functions

Traffic: What is (or should be) the street’s role in the traffic circulation network? Does the street have traffic that doesn’t belong there, or is traffic growth anticipated? If so, describe it.

Parking: What is (or should be) the street’s role in serving the various parking markets (residential primary, residential secondary, commercial, or commuter)? How could parking demand be better managed?

Pedestrians crossing: should the street be pedestrian dominated, or allow crossing anywhere, or have closely spaced crossings, or have infrequent crossings?

Serving bikes: should this be a main bike route with priority to the bike function, or simply meet the general need for bike use and safety?

Does the street host a transit route? Should high quality transit service, including congestion protection, be a high priority?

What “place” functions should the street have (shopping walkway, outdoor seating, play, urban park, etc.) apply?

Design targets

Describe the desired overall street character

Traffic volume target (same as existing, or reduced to xxx vehicles/day by traffic diversions)

Target number of lanes for through traffic

Target speed

Desired level of separation for bicycles (mixed traffic, bike lane, cycle track)

Green space targets and other esthetic targets.

Solution

Answer:- features of Melnea Cass Blvd (Boston) :-

(i) Creating a pedestrian-friendly environment with new sidewalks that are generally 8\' wide:- Side walk is very necessary for street.

(ii) Bike lanes that are separated from vehicles and sidewalks:- It reduces accidents.

(iii) Efficient traffic flow with all-new signal equipment and updated timing:- By help of it , we can save time.

(iv) Better bus stops with space to comfortably wait:- This is very useful for people. They can use bus stop easily.

Design of   street to follow \"Complete Streets\" principles: safe, comfortable design for people of all ages and abilities to walk, bike, take a bus, or drive. The project will support economic development along the corridor.
