Assalamualaikum Warahmatullahi Wabarakatuh
Haarrrooww Mhissiers :)
Good morning and best wishes for you all
Ok, we meet again. In this chance we will
talk about one of major problem in Indonesia, are you can guess what is that ?
… is not exploitation of natural resources, guess it again …. Surrender, ok I
will tell what It is, its traffic jam. Who does not know traffic jam, I think
almost all of you know what is traffic jam and have experience about it,
especially for people who live in city, such as Jakarta and samarinda. In this
video we will not talk about traffic jam in Indonesia but “how to reduce
traffic jam” yes that is our topic for this week video. Talk about traffic jam,
I have three techniques can decrease traffic jam, curious about that three
techniques, ok lets just talk about it.
1. Provide Exclusive Lanes for Public
Transport
Exclusive
public transport lanes means the lane on which the bus or streetcar runs is not
open to private vehicle traffic. Exclusive lanes enable buses and trams to
avoid congestion helping increase their speed, reliability and attractiveness.
Unfortunately, exclusive lanes are often controversial since they ‘take’ space
that could otherwise be used by private vehicles.
Exclusive lanes come in many shapes and
sizes, for example:
·
Taxicabs are allowed to
use exclusive lanes in some cities (e.g. Vienna, San Francisco. Paris).
·
Bicycles are often
allowed to use exclusive lanes.
·
Exclusive lanes can be
time-based, in other words exclusive during certain times (peak periods) and
reverting to mixed-flow or parking lanes at other times.
The
method of separating exclusive lanes from other traffic is an important factor
in determining their effectiveness. Simply put, the better the separation – the
more effective. Painted lanes are least effective and lanes separated by
barriers or on their own right of way are best.
Transit
malls are a type of exclusive public transport lane. They are sections of
street, generally located in a city centre, where several transit lines operate
with little or very limited private traffic. Transit malls can increase urban
livability while making public transport more efficient and attractive to
customers. Well-designed transit malls, including those in San Jose, Portland,
and Denver, are good examples of high-quality urban design and transportation
planning.
Building
a separate right of way (for example, a bus way) is a costly improvement but
can be worthwhile especially if it serves as the catalyst for implementing
other transit priority improvements. Furthermore, even given their high cost,
these improvements can be less expensive than building new heavy rail public
transport systems. The most effective
purpose built exclusive guideways are designed to serve several different
public transport routes (for example, a bus tunnel in a downtown area).
2. Use Regulations and Traffic Engineering
to Control Traffic
Traffic
regulations can be used to reduce congestion impacts on public transport. This
means adding traffic restrictions that help public transport and removing
traffic restrictions that hurt public transport. Examples of traffic
regulations include:
Parking
Restrictions – one main cause of delays to transit vehicles is waiting while
private vehicles maneuver in and out of parking spaces. Parking restrictions
and controls can be implemented to reduce the impact of parking movements on
transit vehicles and to provide space needed for exclusive transit lanes.
Turn
Restrictions – turning vehicles are another significant source of delay for
transit vehicles. Implementing turn restrictions carefully can significantly
reduce these delays.
Transit
Exemption from Turning Requirements – in some cases, restrictions to turning
movements can lengthen and delay transit routes. In these cases, it can be
beneficial to exempt transit from the turning movement restriction.
Loading
Restrictions – historically, vehicle loading on public streets has been a
problem in cities throughout history. In ancient Rome, goods delivery was
banned during the day because of congestion. Careful design of loading areas
can improve transit priority by reducing interference with transit vehicles.
It’s
important to note that traffic regulations (e.g. removing parking) can be
controversial. This means that they should be developed and implemented with
public input, and that they need to be designed to minimize unnecessary
negative impacts. One effective method is including traffic regulations as part
of a comprehensive program designed to improve neighborhood livability.
3. Use Innovative Ideas to Reduce Traffic
Impacts on Public Transport
In
this section we’ll look at two ways of being innovative in reducing the impact
of traffic congestion on public transport:
clever application of exclusive guideway
measures;
New technology.
3.1
Clever Application of Existing Technology
There
are many opportunities to use clever traffic engineering to reduce the impacts
of traffic on public transportation.
Often these combine traffic signals with short sections of exclusive
public transport lanes. Two common
examples are:
·
Queue bypasses are short
sections of exclusive roadway located near an intersection that enable transit
vehicles to bypass congestion at the intersection.
·
Queue jumps are queue
bypass physical improvements with the addition of change in traffic signal
timing that enables transit vehicles to start ahead of private
vehicles—essentially jumping ahead of them.
Implementing
these types of measures involves careful analysis of specific local conditions.
Again the best way to do this is as part of developing a comprehensive plan for
making a street more livable.
An
excellent reference for both specific measures and the process for analyzing
and planning them is the City of Portland’s Transit Preferential Streets
Program Sourcebook (pdf).
3.2 New Technology
New
technologies are being developed that could reduce the impact of traffic
congestion on public transport. Some specific examples include:
Real
time public transport lanes are lanes that use real time traffic control
devices (for example, changeable message signs) to clear street lanes for
public transport vehicles exactly when the PT vehicles are present; when PT
vehicles are not present the lanes are free for use by any traffic. This
concept has been evaluated in research (Eichler, M. “Bus lanes with
intermittent priority: assessment and design.” Master’s Thesis, Dept. of City
and Regional Planning, University of California, Berkeley; 2006) but there are
no actual examples of it in operation yet.
Ok,
that’s all my techniques about how to reduce traffic jam. I hope my knowledge
can be useful for you all. Im sorry if I had a mistakes and thank you. See you next week with
a new topic. Good bye
